F5 LTM Pool Availability State Monitor

Comtrade.F5.BigIp.LTM.Monitoring.LTMPool.Availability.UnitMonitor (UnitMonitor)

Monitors whether the BIG-IP local traffic pool member is in either RED, BLUE or YELLOW state on any of BIG-IP devices in a Sync-Failover group. Local Traffic Pool Members can have different states on different devices.

Knowledge Base article:

Summary

Monitor will trigger critical alert if a critical state is found on any device where the pool is active. For some device member of Sync Failover group to be active for the pool, the pool needs to belong to a virtual server assigned to a traffic group active on that device. In case when pool does not belong to any virtual server, each device from Sync Failover group is considered active device for that pool.

Configuration

The following configuration parameters are customizable:

Debug

When true, writes more information into event log. Default value is false.

Use Cache

If true, cache will be used, in order to minimize impact of monitoring on the F5 BIG-IP device. Default value is true.

Update Interval in Seconds

Recurring scheduled interval in seconds used for running the workflow. Default value is 300 seconds.

Synchronization Time

Synchronization time in a 24-hour format. No default value is specified.

Timeout Seconds

Timeout in seconds. This value is used for setting timeout value to access the F5 BIG-IP device. Default value is 270 seconds.

Monitor Red State

In case that this parameter is set to true, the alert will be created if the pool is in state Red. RED state means that all pool members are unavailable and therefore the pool cannot accept traffic. Default value is true.

Monitor Blue State

In case that this parameter is set to true, the alert will be created if the pool is in state Blue. BLUE state means that the status of at least one pool member is unknown, and no other pool members are available. Default value is true.

Monitor Yellow State

In case that this parameter is set to true, the alert will be created if the pool is in state Yellow. YELLOW state means that no pool members are currently available but any of them could become available later, with no user action required. Default value is true.
