Nimbostratususing active_members <poolname> takes a long time to failover
Hello everyone. I have a quick question
I'm using
when CLIENT_ACCEPTED {
if {[active_members my_pool] < 1 } {
pool new_pool
persist tcp
}

Hi Franko,
I think you made a good call there: If by shutting off the members you mean that you disable the service on the servers themselves, it is most likely a function of the monitor timeout, which by default is 16 seconds. (You can verify that's what you're seeing by disabling the pool members in the LTM config, then the rule action should immediately reflect 0 pool members, without the 15 second delay.)
Setting the monitor timeout lower is possible, but not necessarily recommended, as you'd also have to set the interval for the checks correspondingly lower, at which point you may be unintentionally DoS'ing your servers with health checks.
