Debug SNMP issues with SNMP Tester

With SNMP Tester, you can run simple SNMP requests against a device in your network. This test program is based on the SNMP technologies built in to PRTG.

Benefits

SNMP Tester aims to:

Enable SNMP debugging to find communication and/or data issues in SNMP monitoring configurations.
Perform SNMP walks. You can use the Walk option of SNMP Tester to check OIDs, and to discover OIDs that you can use to access custom monitoring objects. See this article for step-by-step instructions How do I find out which OID I need for an SNMP Custom sensor?.

Findings

If an SNMP connection works with SNMP Tester, it will also work with PRTG.
If you need analysis, check the log file in the SNMP Tester data folder. You will find the exact protocol of every step of an executed SNMP request in that log file.

Download and documentation

See the SNMP Tester page for more information, the documentation, and a download link.
