MRTG-SQUID(1) mrtg MRTG-SQUID(1) NNAAMMEE 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.
