Introduction

This guide will take the user step-by-step through the Lustre Monitoring deployment that the Space Science and Engineering Center uses for monitoring all of its Lustre file systems. The author of this guide is Andrew Wagner (andrew.wagner@ssec.wisc.edu).

Building the Lustre Monitoring Deployment

Setting up an OMD Monitoring Server

The first thing that we needed for our new monitoring deployment was a monitoring server. We were already using Check_MK with Nagios on our older monitoring server but the Open Monitoring Distribution nicely ties all of the components together. The distribution is available at http://omdistro.org/ and installs via RPM.

On a newly deployed Centos6 machine, I installed the OMD-1.20 RPM. This takes care of all of the work of installing Nagios, Check_MK, PNP4Nagios, etc.

After installation, I created the new OMD monitoring site:

omd create ssec

This creates a new site that runs its own stack of Apache, Nagios, Check_MK and everything else in the OMD distribution. Now we can start the site:

omd start ssec

You can now nagivate to http://example.fqdn.com/sitename of your server, i.e. http://example.ssec.wisc.edu/ssec and login with the default OMD credentials.

We chose to setup LDAPS authentication versus our Active Directory server to manage authentication. There is a good discussion of how to do this here: https://mathias-kettner.de/checkmk_multisite_ldap_integration.html

At this point, you can start configuring your monitoring server to monitor hosts, although
