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.
- On the Main tab, click .
- For the Collect Statistics Data setting, select Enabled.
- 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.
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.
Specifying defaults for alert options
Setting the default behavior for alerts ensures consistent alert actions and the
ability to quickly add new alerts based on these standardized options. It is important
to specify default behavior for alerts before you enable the alert options.
- On the Main tab, click .
- If you want Enterprise Manager to send emails when an alert is triggered, in the Email Recipient field, type the email address of the user, or the alias, that you want as the default receiver for alerts.
-
If you want to log alert events to a syslog file:
- Click Save Changes.
