[Xymon] Anyone have a plugin for IBM Datapower?

[Jason Brockdorf]

I wrote one that works with the REST API on ISAM appliances.  I believe they’re pretty similar to the datapower appliances.  There’s 2 parts to it and you’ll need to have node.js installed, as well as the jq - commandline JSON processor executable.  The username and password for the appliance should go on the line immediately following the tag for this host.  I found that putting the user/passwd on the same line as the host/tags made the information show up on the “info” page in xymon and I don’t think you want credentials published there.

 

This particular test only checks to see if any of the junctions are “red” and reports a red status if so.  The entire junction tree is reported along with green/red for good/bad junctions.  I didn’t write in anything for junction specificity, though that’s probably coming soon.

 

The first file I called isam-junctions.sh and the 2nd file I called isam-jct-parse.js

 

I know it’s not exactly what you’re looking for but I hope it will help you to develop one that you can use for the datapower appliances.

Subject: [Xymon] Anyone have a plugin for IBM Datapower?

 

I’ve been asked to monitor an IBM Datapower XML gateway, and wanted to see if anyone else had a plugin to do it before I re-invented the wheel.  They have a mib, so supposedly I can poll it with mrtg and feed statuses into xymon with bbmrtg.pl, but IBM claims that their web service has greater detail and information.  So, if anyone has written a xymon plugin to poll a datapower webservice and come up with useful stats to display in xymon, I’d love to hear about it.
