       mrtg-squid - using mrtg to monitor Squid

       Squid 2.3 knows SNMP and you can therefore use mrtg to monitor it quite

       I have made some modifications to mrtg which simplify this.  My work is
       based on earlier modification made by: matija.grabnar@arnes.si and

       I added new code for displaying correct units to the previous patches
       "perminute" and "perhour" ("option" tokens), which allows other mea
       surement in addition to "persecond".

       Then I created a new option token "dorelpercent" which allows the cal
       culation 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 colour
       name/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

       "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.

       You can measure responsetimes in ms and display it with MRTG correctly

	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
