Hello,
Using Xymon 4.3.7, I am a little confused with the 'procs' test.
As far as I can tell, after installation the 'procs' test will run and a column is produced. Also an RRD (procs.rrd) is created for each client and the server itself. However, the RRD graph is not shown (see my previous email about the 'zoom icon' alone showing), and this seems to be because the 'xymonserver.cfg' file in the TEST2RRD definition has 'procs=processes'.
The comments in the file indicate that this means the column 'procs' will be created, but data for a graph comes from the 'processes.rrd' file. But that file doesn't exist, so no graph.
If I change the 'xymonserver.cfg' file to just say 'procs' in the TEST2RRD section, then I get the graph name showing but still no graph.
It seems that the 'graphs.cfg' file has a section for 'processes', but no section for 'procs', so Xymon does not know how to display the 'procs' graph. If I create a 'procs' section, then I get a graph.
I'm not quite sure where the 'processes' bit comes from, but it seems that perhaps the 'xymonserver.cfg' and 'graphs.cfg' files should only refer to 'procs'. The 'procs' test runs, but produces no graph because, by default, Xymon seems to be expecting 'processes'.
John.

I think the procs=processes mapping is for backwards-compatibility. But it still should work as-is. On my system I simply created a new "[processes]" definition in graphs.cfg to get the graph, like so:
[processes] TITLE Process counts YAXIS processes DEF:cnt=procs.rrd:la:AVERAGE LINE2:cnt#00CC00:Processes GPRINT:cnt:LAST: \: %10.1lf (cur) GPRINT:cnt:MAX: \: %10.1lf (max) GPRINT:cnt:MIN: \: %10.1lf (min) GPRINT:cnt:AVERAGE: \: %10.1lf (avg)\n
I needed no other changes for the graph to show up.
Note that the procs RRD file should be shown on the trends page (as "Users and Processes"), regardless of this adjustment.
Also, I think that there will be no "files" graph unless you define a file with a "TRACK" option in analysis.cfg. Same for "ports".

The default 'graphs.cfg' file already contains a 'processes' section:
[processes] FNPATTERN ^processes.(.+).rrd TITLE Process counts YAXIS # DEF:cnt at RRDIDX@=@RRDFN@:count:AVERAGE LINE2:cnt at RRDIDX@#@COLOR@:@RRDPARAM@ GPRINT:cnt at RRDIDX@:LAST: \: %10.1lf (cur) GPRINT:cnt at RRDIDX@:MAX: \: %10.1lf (max) GPRINT:cnt at RRDIDX@:MIN: \: %10.1lf (min) GPRINT:cnt at RRDIDX@:AVERAGE: \: %10.1lf (avg)\n
As can be seen it filters on the RRD file 'processes'.
Only the default '[users]' section filters on the 'procs.rrd' file.

Nope. With nothing in graphs.cfg saying how 'procs' should be shown and using 'procs.rrd', no graph shows up.

Yes, using the '[users]' section above from the default graphs.cfg file:
[users] TITLE Users and Processes YAXIS # DEF:p=procs.rrd:la:AVERAGE DEF:u=users.rrd:la:AVERAGE AREA:p#00CC00:Processes LINE1:u#000099:Users [snipped]
Also, I think that there will be no "files" graph unless you define a file with a "TRACK" option in analysis.cfg. Same for "ports".
Yes, and 'procs'. Basically any test that doesn't draw a graph by default but requires some configuration to be done. This leads to the problem of no graph showing but the 'zoom' icon alone appearing. I'm still working on how that might be fixed.
It is confusing because basically I end up with a 'procs.rrd' file (after configuring a PROC in analysis.cfg), but nothing in 'graphs.cfg' to say how to display it, and no 'processes.cfg' file but a section in 'graphs.cfg' saying how to display it (if it exists). In xymonserver.cfg (TEST2RRD) it seems that for 'procs' the 'processes' file (service) should be used - but it doesn't exist, 'procs' does. Confusing.

Aha, so it does. Mine is after this one (actually, in an included file) and so it replaces this one.
It seems like there are two ways to get process graphs: one via procs from the standard client messages, and the other via TRACK against one or more process names. There seems to be elements of both in the configuration, and there's a conflict.
I'm guessing that the "procs.rrd" file was the original (requiring a processes=procs mapping), but at some stage the TRACK option was added to create "processes.*.rrd" and graphs.cfg was adjusted, but the other configs weren't fixed up. Due to the mapping, there's a naming collision, and so we can't have both work at the same time.
Cheers Jeremy
