WinSnmp ZenPack

This ZenPack serves two purposes. One is to manage Windows devices via the SNMP protocol; the second is to demonstrate examples of using the Python Collector ZenPack.

The ZenPack is based on two earlier ZenPacks by Ryan Matte:

       ZenPacks.Nova.Windows.SNMPPerfMonitor is available at http://wiki.zenoss.org/ZenPack:Windows_SNMP_Performance_Monitor_%28Advanced%29
       ZenPacks.Nova.WinServiceSNMP can be found on the Zenoss wiki at http://wiki.zenoss.org/ZenPack:Windows_SNMP_Service_Monitor .

ZenPacks.Nova.Windows.SNMPPerfMonitor monitors cpu, memory, paging and processes; ZenPacks.Nova.WinServiceSNMP has a modeler to gather Windows Services components and a template to then gather operational status data.

This ZenPack combines the functionality into one ZenPack and changes the data collection method from using commands to using SNMP. This ZenPack can coexist with Ryan's ZenPacks. In general, names have had "Python" appended to them to make similar objects distinct from Ryan's.

The ZenPack introduces a new device class of /Server/Windows/Snmp and then adds subclasses for different numbers of processors, whereas Ryan's ZenPack works directly with devices under /Server/Windows.

To determine which group to place a server in perform an snmpwalk command for hrProcessorLoad as follows:

snmpwalk -v1 -c <snmp string> <host> hrProcessorLoad

The number of lines corresponds to the number of CPUs.

Unlike Ryan's ZenPack, I have NOT provided exhaustive templates for each different number of processors. A sample is provided; please expand the templates to suit your own device requirements.

During installation and removal the ZenPack rebuilds device relations for all devices within the /Server/WindowsSnmp device class. Depending on the number of devices that you have in that class, it can take a long time. You will notice some errors in the UI while the relations are being rebuilt, which is normal. Please be patient and allow it to complete. After the relations have been rebuilt Zenoss should be restarted.

Make sure that you lock the services to prevent them from being removed during a remodel while a service is down. Modeling will only pick up services that are running. zProperties

       zWinServiceSNMPIgnoreNames: Place the full names of any services that you want to ignore in this line by line.
       zWinServiceSNMPMonitorNames: Place the full names of any services which you explicitly want to monitor (ignoring all others) in this line by line.
       zWinServiceSNMPMonitorNamesEnable: This enables/disables the use of zWinServiceSNMPMonitorNames

Note that you need to remodel your devices for the above to take effect.

Keep in mind that zWinServiceSNMPIgnoreNames is constantly in use. If you put the same service name in both zWinServiceSNMPIgnoreNames and zWinServiceSNMPMonitorNames it will be ignored. Templates

       PyTestSnmpCpu monitors CPU utilisation for each processor and the average total. Uses Python to drive SNMP
       PyTestSnmpMem monitors memory and paging using Python to drive SNMP
       PyTestCmdMemCpu monitors cpu and memory / paging using Python to drive commands. This template is not bound by default.
       PyTestSnmpServProc monitors number of processes and number of services. Uses Python to drive SNMP.
       WinServiceSNMPPython in /Server/Windows/Snmp: This template is required for monitoring services. Do not bind this template to the device. Make sure the template is in the class that the device is in (or a higher class). The template will automatically be used for the windows services components.

Modeler Plugins

community.snmp.WinServiceMap: This plugin is required during modeling. It currently is based on the standard SnmpPlugin. Events

This ZenPack ships 2 events that are used with thresholds and templates. Both have transforms.



The ZenPack Catalog has moved to its new home at https://www.zenoss.com/product/zenpacks as of January 17, 2017. The following information may be out of date, and this page will eventually be removed.


This ZenPack is developed by the Zenoss user community and supported via our online forums. Zenoss, Inc. does not provide direct support for this ZenPack.


Version 1.0.1- Download
Released on 2015/02/12
Compatible with Zenoss Core 4.2.x, Zenoss Resource Manager 4.1.x, Zenoss Resource Manager 4.2.x


This ZenPack has a prerequisite of ZenPacks.zenoss.PythonCollector >=1.6

This ZenPack was developed partly as an illustration of using the Python Collector ZenPack.

There is a draft document available that discusses this usage at http://www.skills-1st.co.uk/papers/jane/PythonZenPacks.pdf


Normal Installation (packaged egg)

  1. Download the appropriate egg file for the version of Zenoss you are running.
  2. Ensure you are logged in as the zenoss user:
    $ sudo su - zenoss
  3. Install the ZenPack:
    $ zenpack --install ZenPacks.skills1st.WinSnmp-*.egg
  4. Restart these services:
    $ Restart Zenoss

Developer Mode Installation

In order to do a development mode installation you will want to clone the existing git repository, and then use the --link flag with the zenpack command:

  1. Ensure you are logged in as the zenoss user:
    $ sudo su - zenoss
  2. Start by cloning the upstream repository:
    $ git clone https://github.com/jcurry/ZenPacks.skills1st.WinSnmp
  3. Next, perform the installation:
    $ zenpack --link --install ZenPacks.skills1st.WinSnmp
  4. Finally, restart these serivices:
    $ Restart Zenoss
