Site24x7 On-Premise Poller uses SNMP to monitor and collect performance metrics from network devices.
Please follow the steps below to check if a network device is reachable through SNMP, from the on-Premise poller using the bundled MIB browser:
Open the Command Prompt as an administrator. From the administrator command prompt, go to the directory where the On-Premise Poller is installed
Then navigate to ../Site24x7OnPremisePoller/Networkplus/bin folder
Execute the MibBrowser.sh or MibBrowser.bat file
Set the SNMP credentials with respect to the version.
For SNMP v1, set the host, port, and the SNMP community.
For SNMP v2, click Edit > Settings > Change the SNMP version > Ok. Set the host, port, and the SNMP community.
For SNMP v3, click Edit > Settings > Change the SNMP version > Add. Set the host, port, username, authentication credentials and click Ok.
Then, navigate the RFC1213-MIB to org.dod.internet.mgmt.mib-2.system.sysObjectID (or) set the value for Object ID field to .126.96.36.199.188.8.131.52
Now click on the Get SNMP variable icon (7th icon from left) below the menu bar
Please check if the device details are fetched successfully.
If a timeout occurs, please check
i) if the host name, port, and the SNMP community are specified correctly.
ii) if there is a firewall blocking SNMP connection
iii) if the On-Premise Poller is on the same network as the device.
iii) There are also chances for the On-premise poller to not be on the list of hosts that are allowed to query the device through SNMP. We request you to check the SNMP configuration on the device for the same. Click here to know more about MIB browser errors.
Alternative steps: If the MIB browser is inaccessible or fails to work, SNMP command line tools can be used to check the SNMP reachability.
