SCOM: Net-SNMP Management Packs for UNIX/Linux Monitoring, Version 1.0.1
September 21, 2009 3 Comments
I have completed version 1.0.1 of the Net-SNMP management packs for OpsMgr 2007 R2 , and I thought I’d go ahead and share them. At this point, my testing of the management packs has been on a small development network with Sun and CentOS servers, but so far everything is looking pretty good. These management packs should provide a pretty good set of monitoring for UNIX and Linux servers that run the Net-SNMP agent, which includes Solaris, most Linux distributions, and even VMWare ESX and Checkpoint Secure Platform.
As I had discussed in my last post, there are two management packs in this set. The Net-SNMP Library management pack defines the classes and performs discoveries. This can be imported by itself to facilitate completely custom monitoring or to be referenced in other management packs. The Net-SNMP Monitoring management pack implements a pretty standard set of monitors for UNIX/Linux server performance and availability monitoring and supports the Exec, Proc, and File directives of the Net-SNMP agent configuration.
The management packs can be downloaded here. They are released under the GNU Public License and can be used, modified, and distributed freely, as long as the attribution remains intact.

Hi Kris,
I must say, your Management Pack is very well written. We’d love to include the hostname in the alerts. Do you know how to do this?
The devicename (from the RFC-1213 MIB) is a property of the base Net-SNMP Device class in the MP. Because all objects are hosted at some level beneath this, the DeviceName property can be added to alerts. I have some updates to do to the MP that I hope to post by tomorrow, and I’ll add that to the list.
Good day!
I downloaded your package, installed on the SCOM 2012 server add Linux as network devices, but they do not primenyaets package, do not tell me what to do?
Thank you.
