Overview: Health and performance monitoring statistics

When statistics data collection is enabled, Enterprise Manager stores the following information in its statistics database for each managed device on which the Data Collection Agent is installed:

  • Specifics about the managed devices, such as host name, IP address, and software version
  • Details, such as object type and name, about any enabled network objects associated with a managed device
  • Performance and health data for managed devices and associated network objects

You can use collected statistics to display standardized reports about the health and performance of managed devices in your network. This helps you identify any systems that are not performing at full capacity and assists you in determining when you should add new devices.

Important: Enterprise Manager collects statistics only from devices that have BIG-IP Local Traffic Manager licensed and provisioned. Starting with Enterprise Manager version 2.3, Enterprise Manager can also collect statistics from devices licensed and provisioned for BIG-IP Global Traffic Manager.

To start collecting statistics, you must enable the collect statistics data feature and install the Data Collection Agent.

Enabling statistics data collection

To collect statistics you must enable data collection, which is disabled by default.
Important: Due to the processing power required to collect and store statistics data, only Enterprise Manager 4000 platform and Enterprise Manager Virtual Edition (VE) support statistics data collection. If you are upgrading from a version of Enterprise Manager that is earlier than 1.7, you must re-license the system before enabling data collection.  
Tip: If Enterprise Manager is managing devices that are part of a BIG-IP Global Traffic Manager (GTM) synchronization group, Enterprise Manager temporarily disrupts communication between GTM and remote BIG-IP objects while it verifies the version of the big3d agent on GTM. To reduce the impact to production traffic relying on the BIG-IP GTM infrastructure, we recommend that you enable statistics data collection during a maintenance window. Alternatively, you can configure the BIG-IP GTM system to maintain an available status for the virtual servers on each managed device while communication is briefly disrupted.
  1. On the Main tab, click Statistics > Options > Data Collection.
  2. For the Collect Statistics Data setting, select Enabled.
  3. Click the Save Changes button.
When you enable statistics collection, Enterprise Manager verifies that each managed device has a compatible version of the Data Collection Agent installed.

Installing the Data Collection Agent

When data collection is enabled, Enterprise Manager collects health and performance monitoring statistics data for each managed device in your network on which the most current version of the Data Collection Agent is installed. If a device on which statistics is enabled requires a more recent version of the Data Collection Agent, Enterprise Manager displays that device as Impaired in the device list, and indicates that an upgrade is required.
You can use the Data Collection Agent Installation wizard to update and install the Data Collection Agent.
  1. On the Main tab, click Enterprise Management > Tasks > Task List.
  2. Click the New Task button.
  3. For the Software Installation setting, click Install Data Collection Agent, and then click Next. The Data Collection Agent Installation screen opens.
  4. For the Device Filter setting, click the Devices with data collection enabled requiring update option. The screen refreshes to display the devices that require an update.
  5. Select the check box next to each device on which you want to install the most recent version of the Data Collection Agent, and click Next. The Task Options screen opens.
  6. From the Configuration Archive list, select an option to include or exclude private SSL keys in the configuration archive.
  7. From the Device Error Behavior list, select an option to specify how you want the system to proceed if an error occurs during the Data Collection Agent installation task.
  8. Click Next. The Task Review screen opens.
  9. In the Task Name field, you can type a new name to customize the name that displays in the task list.
  10. Click the Start Task button. The Task Properties screen opens, displaying the progress of the task. The task progress displays as Finished when the Data Collection Agent is installed.
Enterprise Manager starts collecting and storing health and performance monitoring statistics for the devices on which data collection is enabled and the Data Collection Agent is installed.

About statistics profiles

A statistics profile defines the specific performance monitoring statistics information that you want Enterprise Manager to collect, such as bytes and packets, connections, CPU utilization, memory, and disk usage. The statistics profile types correspond to the type of object that you want to monitor.

To collect performance monitoring statistics, assign one or both of these profile types, to the managed objects in your network.

Standard statistics profiles
A standard statistics profile contains all the required metrics that Enterprise Manager must collect for a specific network object type, to successfully create standard reports.
Custom statistics profiles
A custom statistics profile allows you to define your own metrics and optional threshold values for an object. By enabling or disabling data collection for certain metrics, you can prioritize the information you are collecting, ensuring that system resources are allocated appropriately.

Statistics data collected for the standard statistics profiles

When statistics collection is enabled, Enterprise Manager collects the following statistics data to create standard reports.

Creating a custom statistics profile

Before Enterprise Manager can monitor a device, you must enable statistics collection for that device.
In most cases, a standard statistics profile is best for monitoring objects in your network. With a custom statistics profile, however, you can specify your own minimum and maximum thresholds for a number of object-specific options, providing the flexibility to specify fewer or more metrics to monitor.
  1. On the Main tab, click Statistics > Managed Devices > View.
  2. From the menu bar, select a profile type based on the type of network object for which you are creating a statistics profile.
    • Device Profiles
    • Global Traffic Profiles
    • Local Traffic Profiles
    The Profiles screen specific to that network object type opens.
  3. Click the Create button. The New Profile screen opens.
  4. From the Profile Source list, select an option.
    Option Description
    Standard Profile Select this option if you want to base the custom statistics profile on the metrics currently assigned to the standard profile for this network object type.
    None Select this option if you want to choose from all metrics available for this network object type.
    The Profile Metrics table refreshes to display the metrics associated with the source profile you selected.
  5. In the Name field, type a name for this customized profile.
  6. In the Description field, type details to help you identify this customized profile.
  7. From the Collection Interval list, select the number of seconds that you want Enterprise Manager to collect metrics.
  8. In the Profile Metrics table, select the Collect Data check box next to each metric that you want to collect.
    Important: If you selected the Standard Profile on which to base the custom statistics profile you are creating, you can select additional metrics to collect, but you must retain the current metrics for standard reports to run successfully. If you disable metrics required for standard reports, the report results will be invalid.
  9. In the metric's associated Minimum Threshold and Maximum Threshold fields, type the values the metric must reach for it to display as red in the graph. These values are optional. You are not required to specify a minimum or maximum threshold value to collect statistics for any metric.
  10. Click Save Changes.
To start using this customized statistics profile, you must assign it to specific network objects, or set it as the default for newly discovered devices.

Assigning a statistics profile to a specific device or network object

Before Enterprise Manager can monitor a device, you must enable statistics collection for that device.
Assigning a statistics profile specific to objects in your network makes it easy for you to monitor performance based on standardized settings for that object, or customized settings that you specify.
  1. On the Main tab, click Statistics > Managed Devices > View.
  2. Click the name of the device for which you want to assign a statistics profile.
  3. On the menu bar, click Statistics > Configure.
  4. Verify that the Collect Statistics Data option is set to Enabled.
  5. From the Object Type list, select the object to which you want to assign a statistics profile. The screen refreshes to display the objects for the selected object type.
  6. From the Associated Filter list, select an option to further filter the objects that you want displayed.
  7. Next to the object for which you want to assign a statistics profile, from the Associated Profile list, select a standard statistics profile or custom statistics profile for that object type.
  8. Click Save Changes.
Enterprise Manager begins to collect statistics and report performance based on the selected profile.

Specifying a default statistics profile for newly discovered devices

Before Enterprise Manager can monitor a device, the device must be enabled for statistics collection.
You can assign a default profile (either a standard statistics profile or a custom statistics profile) to start monitoring devices as soon as Enterprise Manager discovers them in your network.
  1. On the Main tab, click Statistics > Managed Devices > Device Profiles.
  2. From the Profile Name list, select the profile that you want to use as the default for any newly discovered devices.
  3. Click Save Changes.
Enterprise Manager applies the profile you selected to any newly discovered devices.

About network object statistics

With Enterprise Manager, you can easily monitor the health and activity of managed objects in your network through collected statistics. You can view activity in a summary and detailed graph format. This information ensures that your network is performing efficiently and helps you to troubleshoot potential issues. Viewing statistics provides you with an overview and details about the health and activity of the objects in your network. You can customize the information displayed in the graphics on this screen by using rule classes. This flexibility provides you the at-a-glance view, while highlighting the statistics you are most interested in.

Displaying network object statistics and customizing view

You must have statistics collection enabled for a network object for Enterprise Manager to collect and display statistics.
You can view network activity based on collected statistics in a standardized or customized format.
  1. On the Main tab, click Statistics > Managed Devices > View.
  2. From the Object Type list, select the object type for the statistics that you want to view. The screen refreshes to display the related statistics in a summary graph. If no statistics exist for the object type you selected, the Data column displays No Data.
  3. From the Rule list, select a rule class to specify the particular statistics displayed. The screen refreshes to display the associated statistics details in the summary graph.
  4. From the Time Span list, select a range of time for which to display data.
  5. Move the cursor over a graph to display a summary, or click the graph to view a detailed graph.

Modifying the number of records per screen to display

By default, Enterprise Manager displays up to 10 records per screen. If there are more than 10 graphs, the screen displays a link where you can view additional graphs. If you want to view more than 10 records per screen, you can increase the number displayed. This global setting affects all list screens on the Enterprise Manager system. Performance can be affected the large number of items to display on a screen.
  1. On the Main tab, click System > Preferences. The Preferences screen opens.
  2. In the Records Per Screen field, type a new value. This is a global setting and that affects all screens that lists records.
  3. Click the Update button.

About statistics storage

Enterprise Manager stores statistical data until the system reaches the storage capacity, which is by default, 1 GB stored locally. When this capacity is met, the oldest data in the system is replaced with new data, up to the storage limit. This default amount is intentionally low because when you enable statistics collection it affects the overall performance of the system. Therefore, it is important to plan for your database storage needs by understanding your system's capacity and personalize your storage requirements so you can maximize the value of the statistics features. Once you have estimated the availability of storage on your system, you can change the default database storage capacity setting. Increasing the default setting is essential to monitoring statistics data over time.

To help you plan for statistics storage, you can view the system's hard drive allocation by file type to remove any unnecessary files and calculate statistics data storage.

Viewing hard drive storage allocation

The Enterprise Manager system hard drive contains all locally-stored statistical data as well as software images, attack signature files, system logs, archives, and so forth. It is important to note that if you are collecting statistics for a large number of devices and objects, the size of the statistics database can be limited by how many other parts of the Enterprise Manager system are using the shared file system. You can view file allocation to determine if storage is maximized for your needs.
  1. In the navigation pane, click System > File System Management > File System Information.
  2. Review the storage allocation to identify any outdated or unnecessary file storage.
You can remove any superfluous files to free storage space to increase statistics data storage.

Calculating and modifying statistics storage allocation

When Enterprise Manager is configured to collect statistical data, the Data Storage screen displays a system-generated estimate of the number of days until the system reaches capacity for statistical data storage.

This number is calculated based on the current rate of data collection and the amount of disk space you specified for the storage space allocation. To retain more or less historical data, you can change the storage allocation space. To help you determine how much disk space you want to allocate to statistics storage, you can recalculate the estimated number of storage days by modifying the storage space. When you have determined that you are satisfied with the storage space value, you can then opt to save the changes.

  1. On the Main tab, click Statistics > Managed Devices > Options > Data Storage.
  2. From the Allocated Statistic Storage Space list, select a value for the number of gigabytes on the external database hard drive.
  3. Click Recalculate.
  4. Review the value displayed for the Estimated Statistics Storage Capacity With Current Settings setting.
  5. Continue to change the Allocated Statistic Storage Space value until you are satisfied with the number of days for the estimated statistics storage.
    Important: If you change the Allocated Statistic Storage Space setting to a value less than the current value, Enterprise Manager removes statistics data from the database, starting with the oldest, until it reaches the new lowered storage limit. For external databases, this value cannot exceed the available amount of disk space of the system on which you set up the external database. Enterprise Manager does not monitor the amount of disk space on the external database.
  6. Once you are satisfied with the number of days statistics are stored, click Save Changes.
Enterprise Manager allocates the specified hard drive space to statistics storage.

About statistics database backup and restoration

You can backup and restore the statistics database from the command line, or you can create a task to backup the statistics database on a regular schedule.

Scheduling statistics database backups

You must enable statistics collection and have content saved to the statistics database, before a scheduled backup can occur.
Scheduling a regular backup for you statistics database ensures you have a the option to restore it in the event of a system failure.
  1. On the Main tab, click Enterprise Manager > Tasks > Schedules > Statistics Database Backup.
  2. From the Backup Data list, select the frequency that you want Enterprise Manager to back up the statistics database. Depending on your selection, the screen refreshes to display associated options.
  3. Specify the day of the week or month, and the time of day that you want Enterprise Manager to review the device's configuration for any changes.
  4. In the Username field, type the user ID that you use to log in to the remote system.
  5. In the Hostname field, type the FQDN of the remote system.
  6. In the Path field, type the file path of the remote system.
  7. Click Save Changes.
If any changes occur during the specified time frame, Enterprise Manager backs up the statistics database.

About external storage for health and performance monitoring statistics

By default, Enterprise Manager stores health and performance monitoring statistics data in the database located on its hard drive. You have the option of configuring Enterprise Manager to store these statistics on a hard drive that is separate (external) from the Enterprise Manager system. Storing statistics on an external database clears space on Enterprise Manager for more storage of archives, images, configuration files, and so forth. A space dedicated only to health and performance monitoring statistic data can also provide you with more historical data storage.

To use an external database for health and performance monitoring statistics storage, you must create the external database and then configure Enterprise Manager to store data on that database.

If you previously collected data locally on the Enterprise Manager system, you have the option to back up and restore the data to the external database.

Task summary

Creating an external database for health and performance monitoring statistics

Storing statistics on an external database clears space on Enterprise Manager for more storage of archives, images, configuration files, and so forth. A space dedicated only to health and performance monitoring statistics can also provide you with more historical data.

You create an external database for statistics storage by issuing SQL commands on a system that is running Oracle MySQLversion 5.1 with patch 52 or later.

Important: To avoid potential time-out issues, start the MySQL instance using the --skip-name-resolve option.
  1. Access the command line of a system that is running Oracle MySQL version 5.1 with patch 52 or later. For specific information about the following commands, refer to your MySQL Reference Manual.
  2. Type: create database <database> , where <database> is the name of the external database.
  3. Type: grant all privileges on <database>.* to <username>@<host> identified by <password> , where <host> includes the IP address of the Enterprise Manager system that is storing data on the external database and <password> is the password for the user name specified.
  4. Type: grant select on mysql.proc to <username>@<host>. This command sets privileges so that the specified user can initiate the required procedures for Enterprise Manager to store and access data on the external database.
  5. Type: set global log_bin_trust_function_creators = 1. This command relaxes the privilege conditions so that Enterprise Manager can create necessary functions and procedures that enable you to store and access statistics data.
You should now edit the MySQL configuration file to optimize the database and avoid potential memory issues.

Backing up a local statistics database to an external statistics database

If you previously collected data locally on the Enterprise Manager system, you can back up and restore the local data to the external database that you created.

  1. On the Main tab, click Statistics > Managed Devices > Options > Data Collection.
  2. From the Collect Statistics Data list, select Disabled.
  3. Click the Save Changes button.
  4. On the system on which the local database is located, create a back up of the data by running the following command: mysqldump -u <user> -p -R f5em_extern> dump.sql, where <user> is the user name assigned to the database.
  5. On the system on which you created the external database, restore the data by running the following command: mysql -u <user> -p -D remotedb < dump.sql, where <user> is the user name assigned to the database.
  6. On the Main tab, click Statistics > Managed Devices > Options > Data Collection.
  7. From the Collect Statistics Data list, select Enabled.
  8. Click the Save Changes button.
You can now configure Enterprise Manager to store health and performance monitoring statistics on the external database.

Configuring Enterprise Manager to store statistics to an external database

After you have created the external database on the remote system, you can configure Enterprise Manager to store data there.

Configuring Enterprise Manager to store health and performance monitoring statistics on an external database frees system resources, and provides you with space to store statistics that is limited only by the system's hard drive on which you configure the external database.

Important: When configured to use an external database for statistics storage, Enterprise Manager no longer monitors, reports, nor sends alerts regarding storage capacity and usage, and you cannot schedule or perform statistics database backups and restorations from Enterprise Manager. When statistics are stored in an external database, the administrator of the remote system on which the statistics are stored must perform capacity management, and backup and restoration tasks independently of Enterprise Manager.

If you have two Enterprise Manager systems configured as a high availability system, configure the external database the same way on each system.

  1. On the Main tab, click Statistics > Managed Devices > Options > Data Storage.
  2. For the Statistics Data Location setting, select External. The screen refreshes to display additional fields specific to the external database option.
  3. In the External Database Address field, type the IP address of the system on which you configured the external database.
  4. In the External Database Port field, leave 3306 for the MySQL default port, or type a new port number in the field.
  5. In the External Database Name field, type a name for the external database.
  6. In the External Database User and External Database Password fields, type the credentials required to access the database.
  7. In the Allocated Statistic Storage Space field, type a value for the number of gigabytes (GB) that you want to dedicate to storing statistics. This value cannot exceed the available amount of disk space of the system on which you set up the external database. Enterprise Manager does not monitor the amount of disk space on the external database.
  8. Click Save Changes. The screen displays a summary of the configuration.
  9. If the summary details are correct, click Confirm to initialize the configuration.
When the configuration changes are fully initialized, Enterprise Manager begins to store health and performance monitoring statistics data in the external database. (This transition may take a few minutes.) Content currently stored in the local database remains there until you remove it.
Removing local statistics data storage
After you configure Enterprise Manager to store health and performance monitoring statistics on an external database location, you can remove the data stored locally to free more disk space. Before removing the local statistics, first verify that external statistics storage, data retrieval, and reporting functionality are working as expected, and that the locally-stored data is no longer useful or relevant. Or, if you want to retain the local data, back up the local data to store elsewhere, prior to deleting it.
Removing the locally-stored statistics increases the amount of storage that Enterprise Manager can use for archives, images, configuration files, and so forth.
  1. On the Main tab, click Statistics > Managed Devices > Options > Data Storage.
  2. Click the Delete Local Statistics Data button.
  3. Click Confirm.
Enterprise Manager frees the local disk space that was previously dedicated to storing statistics data.

Backing up and restoring an external statistics database

Enterprise Manager cannot run scheduled backups and restoration for statistics stored on an external database. When statistics are stored on a remote system, the administrator of must perform backup and restoration tasks independently of Enterprise Manager.

Backing up an external statistics database
You must enable statistics collection and have content saved to the configured external statistics database, before you can create a backup.
If you created an external database for health and performance monitoring statistics storage, you must manually back up that database for archive and restoration purposes.
  1. Log in to the Enterprise Manager command line as root.
  2. Type the em-backup-extern <user@host.com>:/>full_file_path_for_backup_file> command. The default file name is f5em_extern-<date stamp>.
Enterprise Manager saves the stored contents of the external statistics database to the specified file.
Restoring the external statistics database
You must backup the external statistics database before you can restore it.
If you have configured an external database on which to store statistics, and you want to restore data that you have backed up, you must do that from the command line.
  1. Log in to the Enterprise Manager command line as root.
  2. Type the em-restore-extern <user@host.com>:/>full_file_path_for_backup_file> command. For example: em-restore-extern <user@host.com>f5em_extern-<date stamp>.
Enterprise Manager restores the backed-up content of the external statistics database to the specified location.

About reports

You can use Enterprise Manager reports to retrieve and view information about the devices and BIG-IP Local Traffic Manager (LTM) and BIG-IP Global Traffic Manager (GTM) objects in your network. To create a report, you define parameters, the devices from which to collect the data, and the object types you want to include. You can collect data and view the report immediately, or you can schedule the report to run in the future either once, or at regular intervals. Depending on the report type, completed reports are presented in Adobe portable document format (PDF) or comma-separated value (CSV) text, which you can export to a spreadsheet, such as Microsoft Excel. The Capacity Planning report also supports an interactive HTML format.

Important: Before you can use the reports feature, you must enable data collection. You have the opportunity to enable data collection when you create a report. However, if you upgraded to the current version of Enterprise Manager from a version prior to 1.7, you must re-license the system before you can enable data collection. Due to the processing power required to collect and store statistical information, data collection is available only for the Enterprise Manager 4000 platform.

About custom health and activity statistics queries and reports

With Enterprise Manager you can collect statistics and view details about the health and activity of the managed devices in your network. You also have the option use this collected data to create your own queries and customized graphs and reports using the details provided in the following sections in conjunction with any MySQL Connector, (available at http://dev.mysql.com/downloads/connector).

Overview of statistics types

Enterprise Manager stores in its health and performance monitoring database three types of statistics: counter statistics, gauge statistics, and threshold state statistics.

Counter statistics increment periodically to indicate a rate of change. To report the rate of change for a statistic during a specific period of time, the system performs a query for the counter statistics values and the timestamps for the beginning and end of the specified time period. Once the system receives the query response, it calculates and reports the rate of change.

Gauge statistics are absolute values for certain components, such as temperature, fan speed, and current connections. The system does not have to perform a calculation to report the absolute value of a gauge statistic.

A threshold state statistic is the current state of a specific statistic value as it relates to its threshold. That is, the threshold state indicates if the statistic value is above, below, or within a specified threshold.

Counter statistic query sample

The following SQL query example retrieves the counter statistic values for the server_pkts_in field for a node on the host device, bigip-central.

To calculate the rate of change for this example, the system compares the previous value (perfmon_node_stat p) and the current value (perfmon_node_stat c) in the perfmon_node_stat table. With this data, the system calculates the rate of change for the counter statistic using the calculation (V1-V0) / (T1-T0), where V1 is the value of the server_pkts_in field at time c.t, and V0 is the value of the server_pkts_in field at time p.t. (The insert_order field indicates the previous timestamp and value for that particular node.)

SELECT c.t, IFNULL(ABS(ROUND((p.server_pkts_in - c.server_pkts_in) / TIMESTAMPDIFF(SECOND, p.t, c.t))), 0) AS server_pkts_in_per_sec FROM perfmon_device d, perfmon_device_object o, perfmon_node_stat c, perfmon_node_stat p WHERE d.host_name = 'bigip-central' AND o.perfmon_device_uid = d.uid AND c.perfmon_device_object_uid = o.uid AND (p.insert_order = (c.insert_order – 1) AND p.perfmon_device_object_uid = c.perfmon_device_object_uid) AND c.t BETWEEN TIMESTAMPADD(MINUTE, -60, NOW()) AND NOW() AND p.t BETWEEN TIMESTAMPADD(MINUTE, -60, NOW()) AND NOW();

Gauge statistic query sample

The following example shows a gauge statistic SQL query that retrieves all values over the past hour for the chassis temperature on the host device, bigip-central.

SELECT s.t, s.temperature FROM perfmon_device d, perfmon_device_object o, perfmon_chassis_stat s WHERE d.host_name = 'bigip-central' AND o.perfmon_device_uid = d.uid AND s.perfmon_device_object_uid = o.uid AND s.t BETWEEN TIMESTAMPADD(MINUTE, -60, NOW()) AND NOW();

Threshold state statistic query sample

The following SQL query retrieves the current threshold state values for the perfmon_vip_stat.client_pkts_in field for all virtual servers associated with managed devices.

SELECT d.host_name, do.name, t.min_threshold, t.max_threshold FROM perfmon_threshold_state t, perfmon_device_object do, perfmon_device d WHERE t.perfmon_device_object_uid = do.uid AND t.stat_column_name = 'client_pkts_in' AND d.uid = do.perfmon_device_uid
