Betsy,

Here's my first crack at a script to test EMC storage in xymon. I need to expand it to take a list of exceptions to customize disk full alerts for different volumes I think it needs more error checking and a way to check xymon env variables and get them from the client dir if they aren't set. But so far it works.

Comments very welcome. It's my first real perl script. Well done on taking the plunge on developing your own tests!

The lines:

my $REDDOT = '<IMG SRC="/xymon/gifs/red-recent.gif">'; my $YELLOWDOT = '<IMG SRC="/xymon/gifs/yellow-recent.gif">';

should be replaced with:

my $REDDOT = '&red'; my $YELLOWDOT = '&yellow';

Note that the insertion of the appropriate image is done on the xymon server, and should not be hard-coded to a particular image path.

A different approach you can take, is to generate a client message on behalf of your device - it looks like you are already doing the equivalent of [disk] and [uptime] sections, but if the information is accessible and already in a mostly similar format you may be able to fairly easily do [procs], [memory], [cpu], etc. I've done this for some appliances where I can pull some info via SNMP.

Client messages are pretty flexible - if a section isn't there (e.g. [ports]), the server just won't be able to generate a column report on it but otherwise doesn't care. One advantage of this approach is that you can then configure thresholds, etc just as you would for any other client, maintaining centralised test configuration.

You can add your own client message sections like your "nas_rep" test and run a server-side monitor on the client channel. See http://xymonton.org/monitors:check-client

The beauty of the xymon architecture - so many choices...
