Description

This article describes how to troubleshoot SNMP service issues with N-able N-central, such as:

  • Service template related to SNMP service not applied with error No Asset Information Found.
  • SNMP services misconfigured with time out error.

Environment

N-able N-central

Solution

  1. Go to Customer Level. From All Devices view, click your Device.

  2. Click Settings > Monitoring Options > SNMP Settings.

  3. Configure the SNMP Settings to match those set up in the SNMP service on the device.

  4. On the device, verify that SNMP is enabled and accepting SNMP requests from at least the probe IP and the device IP itself.
  5. In a new tab, download the SNMPWalk tool from the link: https://ezfive.com/snmpsoft-tools/snmp-walk/
  6. Once you have verified the device and N-able N-central configuration are correct, try testing from N-able N-central by doing the following:
    Go to Customer level > Configuration > Scheduled tasks > Add/Delete. Click Add > Push Third Party Software.

  7. For Location, choose From My Computer. Browse for and select the SNMPWalk.exe file you downloaded.

  8. In the Command field, adjust the command to appear as below:
    snmpwalk.exe -r:<Device IP Address> -c:"<Community String>" -v:<SNMP Version Number> -os:.1 -p:161

    The -p:161 is optional and is used to define the port. If left in, it will go to 161 as the default. If directing to 162, set that as the default port.

  9. If the task returns the SNMP tree from the device, then N-able N-central is ready to use SNMP services on this device.
  10. If you haven't already done so, configure a Discovery Job to scan this device. Be sure to configure the Job to use the correct SNMP settings.
  11. After the Discovery Job completes, you are ready to add the SNMP based services to the device in N-able N-central.
