Get addresses of unavailable pool members?
Hi folks,
Is there a way to get a list (ip:port) of all marked down members in the pool using an iRule? After detecting all members are down in HTTP_REQUEST:
if { [active_members [LB::s...
Hi Aaron,
I like your idea about building remote polling app to examine LTM pool. I could use iControl for that. Hopefully, it should put less overhead on LTM, than doing it inside iRule.
Is there a way to create an event, tag, or object inside an iRule, fill it with some info, and attach it to the pool member to store on LTM? This way, when connecting with iControl, not only would I know that a pool member is down, but I would also know why. Currently, in iRule, I somewhat have access to the cause of member failure (http_status, lb_failure, momitor timeout), so the external app would get an error message and act upon that (restart webservice if http status is 500, restart server if lb_failed, etc)
I'll look into using a trap as well.
Thanks, Roman
