Description:

This ZenPack is for monitoring filesystems via a different MIB than HOST-RESOURCES (which Zenoss uses by default). The main application for this pack is as follows. If you are running net-snmp on a Solaris server, and AutoMountFS is in use on that server, every time someone logs in to the server their home directory gets automatically mounted. It is then unmounted when they log out. The problem with this is that it wreaks havoc on the SNMP indexes for the filesystems making it impossible for Zenoss to properly monitor them.

Components:

This ZenPack installs a UCDFileSystemMap modeler plugin. It also  installs a UCDFileSystem template in /Devices/Server.

The ZenPack has the following Device Class(es)

• Performance Template UCDFileSystem
  • /zport/dmd/Devices/Server/rrdTemplates/UCDFileSystem        Filesystem template that uses UCD-SNMP-MIB mib. Has a 90%  threshold.

Installation:

To use the pack you have to create a class (or use an existing class)  and replace the HRFileSystemMap plugin with the UCDFileSystemMap plugin.  You also have to copy the UCDFileSystem template to that class and  rename it to FileSystem so that it will collect utilization data from  the proper OIDs.

It is possible to go in to a devices snmpd.conf file (not on zenoss box) and specify  filesystems to expose via the UCD OIDs.

To do this, you would put lines similar to the following at the  end of the snmpd.conf file:

disk /
disk /var
disk /etc
disk /share

Only the filesystems that are specified in the file will then be  exposed via the UCD OIDs.  Their indexes will not be affected by  AutoMountFS.  The modeler plugin and monitoring template included in  this ZenPack can then be used to monitor them.
