Re: [squid-users] Squid 3.1 with MRTG, Not able to get Graphs- squid upgraded to 3.1.8 ( Resolved at last)

Hi List,
At last I could get the MRTG running with squid 3.1.8, though it took
much time. Will be writing a howto soon regarding how to set up mrtg
on FreeBSD.
It was the SNMP_util.pm gave all the trouble as the port maintainers
did some changes of merging. Those who are breaking head with mrtg
kindly have p5-SNMP_Session port to be installed additionally and save
the time.
Hope that may help someone in future.

Thank you so much to those took their valuable time to reply to my
silly doubts and cleared and guided me.

Regards
Babs
