Create/Repeat Alert When A Pool or Node is Down
I know that when there is a status change in a node or pool, an entry is made to the syslog. I have been asked if there is a way to repeat a message of a down condition periodically, say once every five minutes, while a node or pool is down. Preferable, I would be able to specify the nodes and or pools that this type of repeated alerting would happen on. Here is the scenario:
- Prior to a maintenance window, error monitoring in 3rd party monitoring software is suppressed
- Work is completed (patches for example) on certain servers
- As part of the work, server goes offline
- F5 knows this happens and creates alert, but since alerts being suppressed, it is not seen
- Work completes, and monitoring is again enabled
- F5 has already alerted, and does not repeat the alert, so it is missed in the monitoring software
Is there a setting, or possibly a way with iRules or something, that the down condition could be detected and reported on periodically?
Thanks!

I think an external monitor would be the good solution for this. You have to write your script along with some logger, so that it constantly throws logs about the status. But it will flood your log file for x intervals.
On good note, put the logging only for down state, for Up - do not put the logger.
