Re: Probe explaination in ACE

Hi,

There is no precedence. By default the probes have the OR logic. So if any of the probes fails ( rserver OR server-farm ) the rserver will be considered down. You can change this logic by configuring on rserver of serverfarm : fail-on-all. This will change the logic on the configured rserver or server farm only.

In the case of multiple probes per rserver/serverfarm

I didn't get "what exactly you ment by Layer4 health" ?

guys please advise on the above information.

Hi ,

A probe can be associeted with :

  • A real server and then associate the real server with a server farm. You can associate a single probe or multiple probes with real servers within a server farm.
  • A server farm. All servers in the server farm receive probes of the associated probe types.

So in your case there is no difference.
