OpenNMS Audiocast #001: VMware Integration (OUCE2012)

MP3 – 33 minutes 53 seconds, 15.6 MB, Ogg Vorbis version here.

Please send feedback to audiocast AT opennms DOT org.

This episode consists of a barcamp talk delivered at the 2012 OpenNMS User Conference Europe by OGP member Ronny Trommer on the topic of the VMware vSphere integration that Ronny, Markus Neumann, and and their colleague Christian Pape built during a one-day hackathon and have been improving to the point of readiness for merging into the bleeding-edge development branch.

Since this talk was delivered very much off the cuff as a barcamp topic, we don’t have slides. Use your imagination.

0m10s: Introduction

You may have thought the show was dead; that kind of thinking will not serve you well after the zombie apocalypse.

0m51s: Talk

1m32s: wiki page on VMware Perl API monitoring with OpenNMS: http://opennms.org/wiki/VMwareMonitoring

Caveats from the editor:

– Use the GpMonitor sparingly; you can easily kill your OpenNMS server with the overhead of fork()/exec()ing scripts from the poller. My own rule of thumb is that nobody should ever use it.
– Be careful using PHP; the language itself has had several high-profile vulnerabilities disclosed in recent months.

4m21s Christian Pape works at the University of Applied Sciences in Fulda, Germany (aka Hochschule Fulda) http://www.hs-fulda.de/index.php?id=682&L=1

6m34s Event translation: http://www.opennms.org/wiki/Event_Translator

6m53s Steve Jin’s VI Java library: http://vijava.sourceforge.net/; DMTF’s SBLIM WBEM library: https://sourceforge.net/apps/mediawiki/sblim/index.php?title=Main_Page

7m00s Ronny states that VI Java is licensed under the GPL; the project’s FAQ (http://vijava.sourceforge.net/faq.php) states that it uses the BSD license (which is still compatible with the GPLv3)

7m15s SBLIM is indeed licensed under the EPL v1.1 which is incompatible with GPLv3 due to its inclusion of a choice-of-venue clause: http://www.eclipse.org/legal/eplfaq.php#GPLCOMPATIBLE. This is not an insurmountable problem.

18m26s the “JMX Sausage Blaster” is a humorous misreading of the original name of Markus’ JMX-ConfigTool, which was “JMX-SaugBlaser” in homage to the late German comedian Loriot’s sketch “Vertreterbesuch”: https://www.youtube.com/watch?v=aksjhtIhfqg (the SaugBlaser, or “suck-blower”, makes its appearance at 2m40s)

20m05s there is some really annoying GSM interference here; I tried removing it without also obliterating Ronny’s voice but it’s beyond my Audacity-foo.

Most of the steps Ronny is doing during the checkout, comiping, and assembly are documented in the wiki here: http://www.opennms.org/wiki/Developing_with_Git and here: http://www.opennms.org/wiki/Installation:Source

30m02s: Wrap-up

If you’re interested in testing this integration, you can contact ronny at opennms dot org. If you want to try building it yourself or just to see what the code looks like, check out the feature-vmware git branch.

In coming weeks we’ll have at least one more episode, probably two, from talks recorded at the European conference.

Dev-Jam 2012 and the first-ever OpenNMS User Conference Americas will take place during the last week of June. Look for more episodes to come out of those conferences as well.
