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...

CirrostratusYou could use the log command to write something informative to the local filesystem when a pool member is down. Default logging will already tell you whether a monitor failed. If you're using 'Fallback on Error Codes' on the HTTP profile, I don't think that would be logged as we don't log anything by default for individual request/LB failures. In v11, you can use [event info] in LB_FAILED to check why the event was triggered. In v10, I don't think it's possible to determine why LB_FAILED was triggered. However, I'm not sure you'd want to restart services if an individual connection attempt or HTTP request failed. So maybe it only makes sense to trigger the service restart if the pool member is actually marked down.
