- .IX Title "MRTG-SQUID 1"
- .TH MRTG-SQUID 1 "2006-02-03" "2.13.2" "mrtg"
- .SH "NAME"
- mrtg-squid - using mrtg to monitor Squid
- .SH "DESCRIPTION"
- .IX Header "DESCRIPTION"
- Squid 2.3 knows s-1SNMPs0 and you can therefore use mrtg to
- monitor it quite easily.
- .PP
- 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.
- .SH "MODIFICATIONS"
- .IX Header "MODIFICATIONS"
- I added new code for displaying correct units to the
- previous patches *(L"perminute*(R" and *(L"perhour*(R" (*(L"option*(R" tokens),
- which allows other measurement in addition to *(L"persecond*(R".
- .PP
- Then I created a new option token *(L"dorelpercent*(R" 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.
- .PP
- If you use this options please consider that you need a 5th
- colourname/value pair in your Colours statements!
- .PP
- Due to some discussion on this list, I have implemented two
- tokens too:
- .PP
- &*(L"kilo*(R" and *(L"kMG*(R"
- .PP
- &*(L"kilo*(R" should contain the value of k (1000 or 1024), where 1000 is the
- default.
- .PP
- &*(L"kMG*(R" is a comma separated list of multiplier prefixes, used
- instead of "*(L", *(R"k*(L", *(R"M*(L", *(R"G*(L", *(R"T" on the s-1MRTGs0 display. Leave the
- place free, if you want no prefix.
- .PP
- Also an incomplete list of OIDs for the new s-1SQUIDs0 release is
- added.
- .PP
- I hope you enjoy it.
- .SH "CONFIG EXAMPLE"
- .IX Header "CONFIG EXAMPLE"
- You can measure responsetimes in ms and display it with s-1MRTGs0
- correctly with:
- .PP
- .Vb 2
- & kMG[measure-ms]: m,,k,M,G,T
- & short[measure-ms]: s
- .Ve
- .PP
- You can display now MB/s as 1024*1024 B/s with:
- .PP
- .Vb 1
- & kilo[volume]: 1024
- .Ve
- .PP
