Hi All
For purpose of convincing about the squid cahce, I installed and started
monitoring SQUID using mysar "http://sourceforge.net/projects/mysar/";;
Is this % too low or average how much should a optimized squid setup give.
Or should I dig into some more configuration to pump the cache %
How large is your cache?
It is around 556GB, my cache dir details in squid.conf are
cache_dir aufs /opt/var/spool/squid 570000 32 256
How many users are going via Squid?
At present not more than 250 users, but concurrent users will not be
more than 50 users
How long have they been using it (how long has Squid been building up its
cache)?
3 months
How many connection requests do you have per minute/hour/day/whatever makes
sense?
Can you please advice me on how to check for this parameter
How many cache HITs do you see in the log file compared to MISSes (ie: how
often are cached objects being requested)?
Can you please advice me on how to check for this parameter
Simplest way is:
.../access.log | grep -c "HIT"
.../access.log | grep -c "REFRESH"
.../access.log | grep -c "MISS"
The next best is:
squidclient mgr:info
Any other relevant information you can supply might be helpful in providing an
answer.
from the mysar, I get the following information, which I am pasting here
Ah. This last column "5.00%" seems to be the HIT percentage over all
taht traffic.
