I had several semi-related questions re using MRTG for non-SNMP monitoring:
% MRTG usually polls data from a source. Can I "push" data to MRTG instead? % Can I push delayed data to MRTG? Example: I learn just now that monitored variable X was equal to 5 about 15 minutes ago. I don't want to say X=5 w/ the current timestamp, but X=5 with a timestamp of 15m ago. % Can I push out-of-order delayed data to MRTG? Example: I learn now that X=4 about 10 minutes ago, and learn a minute later that X=5 about 15 minutes ago. Can I push X=4 w/ a timestamp of now()-10m and then push X=5 with a timestamp of now()-15m [14m earlier than the X=4 report] later? % Does MRTG store "minimum" values? The mrtg-logfile doc suggests it doesn't. % I'm using MRTG as a 1-variable 'gauge'. In situations like this, do people normally set the second variable (outgoing bytes or whatever) to be constantly 0? % Since I'm not using the 2nd variable, can I somehow hack MRTG to store the minimum value (for the previous interval) there? [eg, setting the 2nd value to -1 times the 1st value and then reversing the graph for the 2nd variable somehow?] % By default, MRTG graphs the 1st var in green, 2nd var in blue, and doesn't graph the max values at all unless Colours[myvar] has a 3rd and 4th value, correct? % My ISP won't let me compile C programs. Is there a pure Perl version of MRTG? [if not, I can compile on another machine and copy the ELF, but that's ugly] % Since MRTG consolidates data, do the log files stay at ~50K each? % Is there a good page of tips/tricks for people using MRTG this way? % My ultimate goal: create graphs like http://limbo.alleged.com/wxfan/stats.html for every METAR station in the world, but also add min/max lines (which should be fairly smooth) to avoid the jaggedness for 1 year graphs (last graph on http://limbo.alleged.com/wxfan/kfbl-temp-dewpoint.html) -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology. We feel that resistance to new ideas and technology is unwise and ultimately futile. _______________________________________________ mrtg mailing list mrtg@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
