BIG-IP device configuration requirements for viewing statistics in BIG-IQ
How do I start viewing BIG-IP device
statistics from BIG-IQ?
Enabling statistics collection during device discovery
- There must be a BIG-IQ data collection device (DCD) configured for the BIG-IQ device.
- The BIG-IP device must be located in your network and running a compatible software version. Refer to K34133507#cm6.0.1 for more information.
- For BIG-IP devices running version 22.214.171.124 or later, you must have AVR provisioned.
- For BIG-IP devices running versions prior to 126.96.36.199, configure Ports 22 and 443 must be open to traffic from the BIG-IQ DCD to the managed BIG-IP devices.
- For BIG-IP devices running version 188.8.131.52 or later, BIG-IQ needs to provide access on Port 443 so that the BIG-IP AVR module can send statistics to the BIG-IQ DCD.
- At the top of the screen, clickDevices.
- Click theAdd Devicebutton.
- In theIP Addressfield, type the IPv4 or IPv6 address of the device.
- In theUser NameandPasswordfields, type the user name and password for the device.
- If this device is part of a DSC group, for theCluster Display Namesetting, specify how to handle it:
For BIG-IQ to properly associate the devices in the same DSC group, theCluster Display Namemust be the same for all members in a group.There can be up to 8 members in a DSC group.
- For an existing DSC group, selectUse Existingfrom the list, and then select the name of the DSC group from the next list.
- To create a new DSC group, selectCreate Newfrom the list, and type a name in the field.
- If this device is configured in a DSC group, for theDeployment Settings, specify how to handle it:
- Initiate BIG-IP DSC sync when deploying configuration changes (Recommended): Select this option if this device is part of a DSC group and you want this device to automatically synchronize configuration changes with other members in the DSC group.
- Ignore BIG-IP DSC sync when deploying configuration changes: Select this option if you want to manually synchronize configurations changes between members in the DSC group.
- Click theAddbutton at the bottom of the screen.The BIG-IQ system opens communication to the BIG-IP device, and checks the BIG-IP device framework.The BIG-IQ system can properly manage a BIG-IP device only if the BIG-IP device is running a compatible version of the REST framework.
- If a framework upgrade is required, in the popup window, in theRoot User NameandRoot Passwordfields, type the root user name and password for the BIG-IP device, and clickContinue.
- If in addition to basic management tasks (like software upgrades, license management, and UCS backups) you also want to centrally manage this device's configurations for licensed services, select the check box next to each service you want to discover.You can also select these service configuration after you add the BIG-IP device to the inventory.
- To enable statistics collection for this BIG-IP device, under Statistics monitoring, select the check box next to each service you want to collect statistics for, and then clickContinue.If you want to enable statistics collection without managing any services, just clear the check boxes for all services.
- Click theAddbutton at the bottom of the screen.
Enable statistics collection for
- The device must already be in the BIG-IQ system inventory.
- There must be a BIG-IQ data collection device configured for the BIG-IQ device.
- At the top of the screen, clickDevices.
- Click the name of the device you want to enable statistics collection for.
- On the left, clickStatistics Collection.
- To begin statistics collection, forCollect Statistics Data, selectEnabled.
- ForModules/Services, click the check box for the types of statistics you want to collect.
- ForFrequency, next toCollect every, select the interval at which you want to collect statistics from this device.
Statistics retention policy overview
- The number of BIG-IP devices you manage
- The number of objects on the BIG-IP devices you manage (for example, virtual servers, pools, pool members, and iRules)
- The frequency of statistics collection
- The data retention policy
- The data replication policy
How long is data in each container retained?
Data is retained in each container for the time period you specify. When the specified level is reached, the oldest chunk of data is deleted. For example, if you specify a raw data value of 48 hours, then when 48 hours of raw data accumulate, the next hour of incoming raw data causes the oldest hour to be deleted.
When does data from one container pass on to the next?
Data passes from one container to the next in increments that are the size of the next (larger) container. That is, every 60 minutes, the last 60 minutes of raw data is aggregated into a data set and passed to the
Hour(s)container. Every 24 hours, the last 24 hours of hourly data is aggregated into a data set and passed to the
Day(s)container, and so on for the
What about limits?
Limit Max Storage tospecifies the percentage of total disk space that you want data to consume on the data collection devices in your cluster.
If more disk space is consumed than the percentage you specified, BIG-IQ takes two actions:
The aggregation policy for your statistics data
retention policy for your statistics data
- At the top of the screen, clickSystem, then, on the left, clickBIG-IQ DATA COLLECTIONand then selectBIG-IQ Data Collection Cluster.The BIG-IQ Data Collection Cluster screen opens. On this screen, you can either view summary status for the data collection device cluster or access the screens that you can use to configure the DCD cluster.
- Under Summary, you can view information detailing how much data is stored, as well as how the data is stored.
- Under Configuration, you can access the screens that control DCD cluster performance.
- Under the screen name, click.The Statistics Collection Status screen opens.
- On the left, clickStatistics Data Collection.The Statistics Collection Status screen displays the percentage of available disk space currently consumed by statistics data for each container.
- To change the retention settings for your statistics data, clickConfigure.The Statistics Retention Policy screen opens.
- In theKeep real-time (raw) data up tofield, type the number of hours of raw data to retain.You must specify a minimum of 1 hour, so that there is sufficient data to average and create a data point for theKeep hourly data up tocontainer.
- In theKeep hourly data up tofield, type the number of hourly data points to retain.You must specify a minimum of 24 hours, so that there is sufficient data to average and create a data point for theKeep daily data up tocontainer.
- In theKeep daily data up tofield, type the number of daily data points to retain.You must specify a minimum of 31 days, so that there is sufficient data to average and create a data point for theKeep monthly data up tocontainer.
- In theKeep monthly data up tofield, type the number of monthly data points to retain.Once the specified number of months passes, the oldest monthly data set is deleted.
- In theLimit max storage tofield, type the percentage of disk space that you want collected data to consume before the oldest monthly data set is deleted.
- Expand Advanced Settings, and then select theEnable Replicascheck box.Replicasare copies of a data set that are available to the DCD cluster when one or more devices within that cluster become unavailable. By default, data replication for statistics is not enabled. Disabling replication reduces the amount of disk space required for data retention. However, this provides no protection from data corruption that can occur when you remove a data collection device. You should enable replicas to provide this protection.
- When you are satisfied with the values specified for data retention, clickSave & Close.
