rrd graphs in Xymon

Hi all,

I've got an unusual issue at the moment with Graphs.

I've written a script to collect Average Disk Queue Length from Windows
servers and am looking to add a graph.

I've configured the data as NCV in Xymonserver.cfg and I've created the
graph definitions. Unfortunately because I have different number of
disks on each server it's not working unless the server has exactly the
number of disks that I have set up in the graph definition.

At the moment the only 2 ways I can think of to get around this is to
either have a different column name for each server (which would be very
messy) or to change my script so that it will output lines for 10 disks
even if it only has 1, so for example I would have this,

Disk0 : 1

Disk1 :
Disk2 :
Disk3 :
Disk4 :
Disk5 :
Disk6 :
Disk7 :

Disk8 :

Disk9 :

Not as messy as the different columns but still a bit untidy.

Does anyone know a way to define a graph so that it will still work even
if it doesn't find data in the rrd file for one or more of the DEF
statements in the graph definition?

Only general/practical way to do this is to have an RRD for each disk. I
have done the same thing you are trying to do using devmon and
SNMP-Informant which exposes WMI data through SNMP. Then you can choose
to display 1 graph per disk or group a number together.

devmon sends its data via the status message as below:

<!--DEVMON RRD: dperf 0 0
DS:qlen:GAUGE:600:0:U DS:bps:GAUGE:600:0:U DS:rbps:GAUGE:600:0:U DS:wbps:GAUGE:600:0:U
C 0:124800:0:124767
D 0:0:0:0
Total 0:124774:0:124767
HarddiskVolume1 0:0:0:0
-->


The same thing can be done with a data message to trends pseudo-column
(good idea to also send a status message to create a page with current
data values) which I have done with various Powershell monitoring
scripts - note 1 block per disk, but the RRD definitions are repeated:

data myhost.trends
[dperf.C.rrd]
DS:qlen:GAUGE:600:0:U 0
DS:bps:GAUGE:600:0:U 124800
DS:rbps:GAUGE:600:0:U 0
DS:wbps:GAUGE:600:0:U 124767

[dperf.D.rrd]
DS:qlen:GAUGE:600:0:U 0
DS:bps:GAUGE:600:0:U 0
DS:rbps:GAUGE:600:0:U 0
DS:wbps:GAUGE:600:0:U 0

...

How does xymon handle graphing file system utilization.  However it does that thwn I would think you could do same thing as hists have many different numbers of filesystems or drive letters in the windows world.
