Hi

Is there a squid-snmp-oid or a squidclient-option to get the following
values (since startup of squid or since creation of cache_dirs)?

- tcp_miss
- tcp_hit
- tcp_mem_hit

If not, how can I determine these values?
Thanks a lot.

http://wiki.squid-cache.org/Features/Snmp#Squid_OIDs

Under "Per-Protocol Statistics" OIDs:

MISS = cacheProtoClientHttpRequests - cacheHttpHits
HIT = cacheHttpHits

The individual cache storage locations are not accounted separately. So MEM_HIT are not available.

The same details can be found under squidclient mgr:utilization with various time-brackets of accumulation.

Please be using
 Current Stable Squid 2.7.STABLE9 or 3.1.9
 Beta testers wanted for 3.2.0.3

I recently created the patch below to allow HTTP HIT KB's to be retrieved via SNMP. This is for 3.0STABLE19 and not sure if it's transferable to other version. I'm not an experienced coder so if anyone has any feedback on this (e.g if there are any problems with the patch) I'd like to hear:
