Summary

This monitor checks if configuration within F5 BIG-IP devices in Sync Failover Group is synchronized.

Configuration

The following configuration parameters are customizable:

Synchronization Time	Synchronization time in a 24-hour format. No default value is specified.
Use Cache	If true, cache will be used, in order to minimize impact of monitoring on the F5 BIG-IP device. Default value is false.
Timeout Seconds	This value is used for setting timeout value to access the F5 BIG-IP device. Default value is 270 seconds.
Update Interval in Seconds	Recurring scheduled interval in seconds used for running the workflow. Default value is 300 seconds.
Debug	When true, writes more information into event log. Default value is false.
Monitor Red State	In case that this parameter is set to true a critical alert will be created if the Sync Failover Group configuration is in state Red. RED state means that not all devices are synced, a validation error occurred while syncing, or an error in trust domain. Default value is true.
Monitor Blue State	In case that this parameter is set to true a warning alert will be created if the Sync Failover Group configuration is in state Blue. BLUE state means that some of the devices in Sync Group are awaiting the initial config sync or the local device is not a member of the selected device group. Default value is true.
Monitor Yellow State	In case that this parameter is set to true a warning alert will be created if the Sync Failover Group configuration is in state Yellow. YELLOW state means that changes are pending or there is a possible change conflict between some of the devices in Sync Group. Default value is true.
Monitor Other State	In case that this parameter is set to true a warning alert will be created if the Sync Failover Group configuration is in state Other. Default value is true.

Causes

Configuration within devices in Sync Failover Group not being synchronized might be caused by number of possible reasons, such as any of the following:

Device_name1, device_name2, etc. did not receive last sync successfully.
A validation error occurred while syncing to a remote device.
Error in trust domain.
There is a possible change conflict between device_name1, device_name2, etc.
Device_name1, device_name2, etc. awaiting the initial config sync.
The local device is not a member of the selected device group.
Not logged into the primary cluster member.
