- mrtg-squid - using mrtg to monitor Squid
- DDEESSCCRRIIPPTTIIOONN
- 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.
- MMOODDIIFFIICCAATTIIOONNSS
- I added new code for displaying correct units to the pre-
- vious 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 dis-
- play 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 dis-
- play. 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.

- 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:
- Target[proxy-hit]: cacheHttpHits&cacheProtoClientHttpRequests:public@proxy
- 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>
- Suppress[proxy-srvkbinout]: y
- LegendI[proxy-srvkbinout]: Traffic In
- LegendO[proxy-srvkbinout]: Traffic Out
- Legend1[proxy-srvkbinout]: Traffic In
- Legend2[proxy-srvkbinout]: Traffic Out
- YLegend[proxy-srvkbinout]: per minute
- ShortLegend[proxy-srvkbinout]: b/min
- kMG[proxy-srvkbinout]: k,M,G,T
- kilo[proxy-srvkbinout]: 1024
- Options[proxy-srvkbinout]: nopercent, perminute
