Hello Everyone,
my name is Peter Piela, and I work for a company named Terascala. We make
high performance storage appliances based on the Lustre parallel filesystem. We
have been using collectl to monitor Lustre for several years. During that time
we have made several enhancements to the data collector, and added support for
Lustre 2.x (tested up to 2.1.5). Last Fall I contacted Mark Seger about
contributing our changes back to the community. He suggested that we make the
Lustre data collector a separate plugin, and take ownership for its ongoing
development.
This plan made sense to us; initial development is complete, and we are looking
for beta testers who are willing to try the plugins and provide feedback. Below
are some high level notes describing the scope of the new plugins.
* The Collectl Lustre plugins (lustreMDS, lustreOSS, and lustreClient)
are based on the built-in Collectl 3.6.9 code
* The plugins add support for Lustre 2.x (tested up to 2.1.5), and
remove support for Lustre versions pre 1.8 and HPSFS
* The plugins add new data collection options. Most of the new data
elements are only available via Ganglia export; however, I am more than happy
to work with users on extending the console reports and plots
* The plugins are not compatible with the 3.6.9 version of gexpr.ph
(Ganglia export). Our extensions to the Ganglia export mechanism will be
incorporated into the next collectl release
If you are interested in testing the Lustre plugins let me know, and I will
provide you with software, and basic documentation that describes their usage.
Peter
