SNMP setup on Windows for Zenoss

Intenally we use Zenoss to monitor our servers and systems. In order for Zenoss to query lots of details on the windows servers we are using the free snmp informant program on each Windows host. http://www.snmp-informant.com/ the free version has distribution restrictions but can be used for any purpose for free.

To get this working (based on Win 2003 - other versions of windows might deviate slightly):

  1. In Add Remove Programs, windows components, inside "Management and monitoring Tools" select "Simple network management Protocol". This will probably require the windows installation media.
  2. While in there install the "WMI SNMP Provider" which is also needed by Zenoss.
  3. Windows SNMP service properties, security add community name you want to use to secure this service, read only. Accept snmp packets from specific hosts.
  4. Install SNMP informant
  5. Allow port 161 UDP through firewall for SNMP traffic
A Zenoss server will now be able to report on CPU, HDD, software installed etc.

Troubleshooting:
If WMI not connecting Check firewall
#netsh firewall set service RemoteAdmin enable to enable WMI
A great page for identifying issues is http://community.zenoss.org/docs/DOC-2520 which lists most common errors with monitoring windows devices.

  1. I used Total network monitor for monitoring servers on Windows, but I want to try something new for compare. Zenoss looks good, thanks for the article.
