[Xymon] custom graph- variable datasets?

[Scot Kreienkamp]

Kevin,

You need to look at SPLITNCV.  It's quite easy actually, I just changed mine to that yesterday because of the same problem.

Change your NCV_test to SPLITNCV_test.  You can also use wildcards, so you could write it like mine:

SPLITNCV_F5="*:GAUGE"

Here's my graphs config for an example to look at.  BTW, the dataset name will always be lamda no matter the rest of the config, so don't change that.

[F5]
        FNPATTERN ^F5.(.+).rrd
        TITLE Connections from F5
        YAXIS % Number of Connections
        DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
        LINE2: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

Subject: [Xymon] custom graph- variable datasets?

Is there a way to have variable datasets? Meaning that sometimes my scripts will have 2 datasets and other times I will have 3 datasets. Currently when sending the 3 items the graph works, but when only 2 the graph is not there.

So my scripts will send one of the following:
data01 : 56
flash01 : 4
redo01 : 1

or
data01 : 56
flash01 : 4



Here are parts of my configuration:

Hobbitserver.cfg
TEST2RRD="...,test=ncv"
NCV_test="data01:GAUGE,flash01:GAUGE,redo01:GAUGE"


Hobbitgraph.cfg
[test]
        TITLE test
        YAXIS % Used
        DEF:data=test.rrd:data01:AVERAGE
        DEF:flash=test.rrd:flash01:AVERAGE
        DEF:redo=test.rrd:redo01:AVERAGE
        LINE2:data01#FF0000:data01
        LINE2:flash01#00CCCC:flash01
        LINE2:redo01#00FF00:redo01
        COMMENT:\n
        GPRINT:data:LAST:data01\: %5.1lf%s (cur)
        GPRINT:data:MAX: \: %5.1lf%s (max)
        GPRINT:data:MIN: \: %5.1lf%s (min)
        GPRINT:data:AVERAGE: \: %5.1lf%s (avg)\n
        GPRINT:flash:LAST:flash01\: %5.1lf%s (cur)
        GPRINT:flash:MAX: \: %5.1lf%s (max)
        GPRINT:flash:MIN: \: %5.1lf%s (min)
        GPRINT:flash:AVERAGE: \: %5.1lf%s (avg)\n
        GPRINT:redo:LAST:redo01\: %5.1lf%s (cur)
        GPRINT:redo:MAX: \: %5.1lf%s (max)
        GPRINT:redo:MIN: \: %5.1lf%s (min)
        GPRINT:redo:AVERAGE: \: %5.1lf%s (avg)\n
