Hi,
I have servers running Squid 2.6 Stable 12 and have managed to install MRTG
2.15.2 on these servers. In view that there are so many graphs seen for
monitoring of squid using MRTG, kindly advise what are the necessary graphs
that I can plot to determine squid performance.
I am also getting SNMP error when cacheClientHttpRequests,
cacheCurrentLRUExpiration, cacheCurrentUnusedFileDescrCount and
cacheCurrentReservedFileDescrCount are being turned on.
SNMP Error:

What do these graphs showed and are they necessary to be activated???
Thank you.
