Hello Xymon mailing!

I'm facing the following challenge; I would like to graph the actual disk space used instead of the percentage.
One of the reasons I want to do this is because I want to keep track when I last expended my disk etc...

I read the rrd documentation about graphing but I can't get my head around how I can make xymon do it.
Can anybody point me in the right direction? Does the default disk test from bbwin collect the right data for rrd to do this?

Thanks in advance!

I've never used bbwin, but I would think you can get the details you need
from the client data.  Have a look at the client data for a [df] section or
somewhere showing disk sizes.

If it's there, then you could create a server-side script to extract that
section using the "clientlog" command to fetch the client data.  Something
like:

DISKDATA=`$XYMON $XYMSRV "clientlog name.of.server section=df"`

After parsing the disk data, you can create your own status (if you also
want alerting) or data message with NCV formatted data lines, and Xymon
will put it into RRD files for you, and show it on the trends page.  Or
send a trends message for more control over the RRD file creation.  See the
"Custom Graphs" doco here:  http://www.xymon.com/xymon/help/howtograph.html

Click on the disk graph and change the url: disk -> disk1
You can add this to the trend page if you want, see the GRAPH parameter in bb-
hosts.
