CSM - multiple probes behaviour

On a CSM, if there is more than one probe configured on a serverfarm, lets say 3 probes, ping, http and port 4400, if one of these probes fails then is the real server marked as failed, or do all 3 probes have to fail before the server is marked as failed, or is the specific service on the real server marked as down ?

Thanks in advance.

Re: CSM - multiple probes behaviour

Dear Peter,

If you associate a probe of a particular type (http, icmp, etc)with a server farm containing real servers that are not running the corresponding service, the real servers send error messages when they receive a probe of that type. This action causes the CSM to place the real server in a failed state and disable the real server from the server farm.

If any of the probe failed, It will fail the real server.

Re: CSM - multiple probes behaviour

when you configure multiple probes for the same serverfarm, all of them

have to be succeful in order to maintain the servers in OPERATIONAL

state: a failure of just one of the probes would put the server in

PROBE_FAILED state.

Gilles.
