Re: squid client or cache manager under Multi instance squid /SMP

[Peter Viskup <skupko.sk@xxxxxxxxx>]

Hello Ahmad,
your instances should have different ports opened. Use squidclient's options -p -h to request the appropriate instance.

Example from our server:

proxy02:/etc/squid $ squidclient -p 8080 cache_object://localhost/ mgr:info|grep "Start Time"
Start Time:     Thu, 22 Mar 2018 13:09:24 GMT
proxy02:/etc/squid $ squidclient -p 3128 cache_object://localhost/ mgr:info|grep "Start Time"
Start Time:     Fri, 23 Mar 2018 13:03:20 GMT

Not sure whether it is possible to get per-thread stats.

It also depends on the Squid's version as stated on wiki [1]. Only versions 3.5+ can be run as multi-instance with SMP enabled.

More information about how the load is distributed across SMP threads is on another wiki page [2].
