  • The screenshot below gives you a brief overview of how the target machine is configured in relation to the node in Orion. The Credentials Set Library is required, but this view does not indicate it. If left empty, an error will occur on "submit" even if the "test" passes with a "Test Successful." See SNMP credentials for the Orion Platform for more information.

  • If the test fails, start by completing an SNMP Walk against the device in question while collecting a Wireshark. The SNMP Walk tool can be found in C:\Program Files (x86)\SolarWinds\Orion\SnmpWalk.exe (or the install directory Orion was placed on). Usually, there is a more meaningful error presented in this tool when a failure occurs.  
  • If the SNMP Walk succeeds and has the 3 needed OIDs, but the node test fails, it could be due to the SNMP username and traps being the same. This will cause some devices to fail.

  • To review the Wireshark you collected during the failure, you will need to decrypt the capture with the following steps:
  1. Open Wireshark and click on Edit and then Preferences.  
  2. Expand Protocols and scroll down to select SNMP.  
  3. Click Edit next to Users Table and then click New.
  4. Enter your SNMPv3 credentials here to decrypt the Wireshark.
