Hi everyone.

Using two custom external scripts, I have Xymon monitoring and graphing 3 temperatures from one device and 1 additional temperature from another device.

Script(s) exist here: http://www.revpol.com/monitortemp

Since the script was written to poll one device and up to 4 temperatures on that device, each device represents one column/test in Xymon with 1 or more temperature graphs using splitnvc.

I'd like to combine all 4 temperatures on one graph - without rewriting my external script to poll both devices and report all 4 temps in one report if possible.

Any hints, ideas?

You can write a graph definition in graphs.cfg which pulls data from multiple RRD files, so it should be fairly simple to have one graph with multiple sources representing the various temperatures.

Hi Henrik. Yes, it should be simple, but for some reason I can't seem to wrap my brain around it.

If I have two tests temp_a and temp_b, and the temp_a device reports back three temperatures (temp-1, temp-2, and temp-3) which appear on one graph as defined in graphs.cfg by :

[temp_a] FNPATTERN temp_a.(.+).rrd TITLE Device temp_a YAXIS Fahrenheit DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE LINE1.5:p at RRDIDX@#@COLOR@:@RRDPARAM@ GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur) GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max) GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min) GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

And is viewed by: http://xymon.example.com/xymon-cgi/svcstatus.sh?HOST=xymon.example.com&SERVI...

Can I modify the FNPATTERN to include temp_b.temp-1.rrd, and temp_b.temp-2.rrd etc, or do I need to have specific DEF lines for each rrd file I want to include if they are not from the same test?

OR, I would think it might make more sense to have a new graph that would pull in just the temperatures from device "temp_a" and device "temp_b" that I would want on one graph... But then, wouldn't I need to define a new column,/test, and also specify the new test in xymonserver.cfg's TEST2RRD and GRAPHS lines as well as add a SPLITNCV_NewGraph-Test="*:GAUGE" line?

I thought I'd spend about 10 minutes on this.. That was five days ago...

So, yeah, it should be simple, but I am really struggling with this one - while in the middle of other projects etc... lol

Any help, or suggestions on the most logical and sensible way to do this would be much appreciated. :)
