ACE show serverfarm - failure counter does not incremented on Probe-Failure event

Hi,

Despite of probe-failure the failure counter is not incremented. Is there any correlation between the configured probe and the failure counter?
(Custom script probe is used for this serverfarm)

# sh serverfarm xxxxxSt
serverfarm     : xxxxxSt, type: HOST
total rservers : 2
---------------------------------
                                                ----------connections-----------
       real                  weight state        current    total      failures
   ---+---------------------+------+------------+----------+----------+---------
   rserver: xxxxx6
       10.222.0.90:8000      8      OPERATIONAL  13         157        0
   rserver: xxxxx7
       10.222.0.92:8000      8      PROBE-FAILED 0          0          0

Thanks,
Attila

Re: ACE show serverfarm - failure counter does not incremented o

Hi Attila,

The Connection Failure counter under show serverfarm is for Loadbalanced Connections which are failing.
If Probes are failing, this counter will not increment.

The Connection failure counter can increment for various reasons some of them are,
- Server not responding to the SYN packet sent by ACE for Loadbalanced connection
- Server sending Reset to the SYN packet sent by ACE for Loadbalanced connection


To check on stats for Probe, you can run "show probe detail" command.

Hope this helps,

Best Regards,
Rahul
