mrtg-squid(1) -- Linux man page
NAME
mrtg-squid - using mrtg to monitor Squid
DESCRIPTION
Squid 2.3 knows SNMP and you can therefore use mrtg to
monitor it quite easily.
I have made some modifications to mrtg which simplify this.
My work is based on earlier modification made by:
matija.grabnar@arnes.si and kostas@nlanr.net.
MODIFICATIONS
I added new code for displaying correct units to the
previous patches ``perminute'' and ``perhour'' (``option'' tokens),
which allows other measurement in addition to ``persecond''.
Then I created a new option token ``dorelpercent'' which
allows the calculation of the percentage of IN-stream / OUT-stream on
the fly and then displays it on a fixed scale from 0% to 100%. For my
requirements, this does good work. Maybe someone wants a floating
scale. It should not be a problem to implement it, too (but
give me an option to keep my fixed scale). If IN-stream is always
less than OUT-stream both lines (OUT-stream and relative percent)
are always displayed on top of IN-stream bulk. Otherwise this
option makes no sense. With this option you can display hitrates,
errorrates (for router monitoring: rel. droprates) easily now.
If you use this options please consider that you need a 5th
colourname/value pair in your Colours statements!
Due to some discussion on this list, I have implemented two
tokens too:
``kilo'' and ``kMG''
``kilo'' should contain the value of k (1000 or 1024), where 1000 is the
default.
``kMG'' is a comma separated list of multiplier prefixes, used
instead of "``, ''k``, ''M``, ''G``, ''T" on the MRTG display. Leave the
place free, if you want no prefix.
Also an incomplete list of OIDs for the new SQUID release is
added.
I hope you enjoy it.
CONFIG EXAMPLE
You can measure responsetimes in ms and display it with MRTG
correctly with:
kMG[measure-ms]: m,,k,M,G,T
short[measure-ms]: s
You can display now MB/s as 1024*1024 B/s with:
kilo[volume]: 1024
A sample config for squid:

Title[proxy-hit]: HTTP Hits
PageTop[proxy-hit]: <H2>proxy Cache Statistics: HTTP Hits / Requests</H2>
Suppress[proxy-hit]: y
LegendI[proxy-hit]: HTTP hits
LegendO[proxy-hit]: HTTP requests
Legend1[proxy-hit]: HTTP hits
Legend2[proxy-hit]: HTTP requests
YLegend[proxy-hit]: perminute
ShortLegend[proxy-hit]: req/min
Options[proxy-hit]: nopercent, perminute, dorelpercent
Target[proxy-srvkbinout]: cacheServerInKb&cacheServerOutKb:public@proxy
Title[proxy-srvkbinout]: Cache Server Traffic In / Out
PageTop[proxy-srvkbinout]: <H2>Cache Statistics: Server traffic volume (In/Out) </H2>
