- Al_Carandang_11NimbostratusJust curious what you mean by "passive" health monitor...
- JRahmAdminVersion 9.4 is supposed to have passive monitoring features, not sure how that ties into iRules though
- JRahmAdminLocalDirector had a nice passive monitoring process whereby it took a server out of service when X consecutive syn packets went unanswered. I wish the LTM supported this on the monitoring side. You can affect an LB_FAILED event and reselect based on your tcp profile, but this tuning should be available as a simple monitoring scheme.
- David_Bradley_2NimbostratusI found this from the LTM 9.4 release notes... I can't find any other documentation. F5 consultants were onsite and mentioned passive monitoring as a possible solution to my problem.
- Vincent_AnielloNimbostratusI just opened a case with F5 support on this same issue. Once they point me to the documentation for this feature I will post the info here.
- dennypayneEmployeeBasically what this involves is looking at the HTTP status codes that come back in the HTTP_RESPONSE event and invoking LB::reselect if it's a 404 or 500 or something like that. I believe LB::reselect is new in 9.4.

- JRahmAdmin
Passive monitoring in 9.4 is specific to HTTP response codes.
- ArieAltostratusWhere is passive monitoring enabled/invoked? I need to mark down nodes as soon as a server error occurs. Waiting for a regular monitor takes too long.
