Enabling SNMP on Windows OS

Open up the Control Panel and go to Programs.  Click on “Turn Windows features on or off”







Check the box to enable SNMP.  Dont forget to enable the WMI as this adds additional OID’s for you to monitor.






Open up SERVICES and find the SNMP Service and double click on it.  This will provide you with a Service Dialog box.







Click on the AGENT tab.  Type in your contact info (such as your email or phone number).  Type in the Location and/or Name of this server you are monitoring.  Make sure to select ALL check-boxes.









Click on the SECURITY tab and select the radio button that says “Accept SNMP packets from any host”

(NOTE: as long as you only set Read Only access to the Community string in Step 6, there is NO security risk)








Click on The ADD button to add a new Community string.  My suggestion is to add a community string that is not the standard “public” community string.  Make up a string that fits your Company, department, etc…, and make sure you set it as READ ONLY!









Open up the SERVICES window and you can now restart the SNMP service and you are ready to monitor your server!

(NOTE: you will need to enable port 161 for SNMP traffic if you have a firewall between your monitoring system and the server you just configured)

Ensure that the SNMP configuration exists at /etc/vmware/snmp.xml and looks similar to:


Ensure that there are no white spaces or extra line breaks in the /etc/vmware/snmp.xml file.

If you do not see the file, or you get an “Load persistent store failed” error, you can delete the file and recreate it: 
  1. To create the file manually:
    1. Run this command to rename the /etc/vmware/snmp.xml file as snmp.xml.old:mv snmp.xml snmp.xml.old
    2. Create a new snmp.xml file using a text editor. For example, to create the file using the vi editor, run this command:vi /etc/vmware/snmp.xml
    3. Copy and paste these lines to the file:<config>
      </config>Note: Ensure that you do not have any extra line breaks or white spaces before or after the text.
    4. Save the file.
    5. Run this command to restart the VMware Management service for ESX4.x: service mgmt-vmware restart  OR for ESX 5.x: /etc/init.d/hostd restart
