I like the UCD OIDs better than the ones that zenoss uses as default.

I have setup my snmpd.conf on the server I am testing from like above with

disk /

disk /home

disk /opt

disk /usr

disk /var

disk /boot

disk /dev/shm

disk /tmp

but I am getting bad OID errors when i run zensnmpperf run on the device

WARNING zen.zenperfsnmp: Error reading value for "/var" on m-pp-mpsweb01.advertising.aol.com (oid .1.3.6.1.4.1.2021.9.1.8.39 is bad)

Also, what does the UCDHardDriveMap plugin do?

Thanks.

Did you copy the UCDFileSystem template in to the class that you want to monitor and rename it to FileSystem as specified in the installation instructions?

"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."

Also, after you specify the filesystems in your snmpd.conf make sure you restart snmpd.

The UCDHardDriveMap plugin isn't part of this pack. It comes with Zenoss and models the physical hard disks rather than the filesystems. It does the monitoring with the HardDisk template that's in /Server/Windows. I believe it may be Windows specific.

Thanks for the quick reply Ryan.

I overrode the template to the device class my test server was in and then renamed it filesystem. I assume that is what you were saying, right?

SNMPd was already setup for with disk parameters and restarting as I was trying out the UCD OID for disk percent.

You are also using the UCDFileSystemMap modeler plugin correct? This ZenPack was developed for net-snmp on solaris but the OIDs should be the same in Linux. I developed this for a very specific purpose. I eventually found that UCD was an unreliable method (net-snmp wouldn't always present the defined filesystems properly and we'd constantly have to fiddle with snmpd.conf files). I eventually stopped using it and switched to using ssh instead.
