Monitor LEM from NPM and the Orion Web Console using SNMP

Updated: October 5, 2018

If you use Network Performance Manager (NPM) and the SolarWinds Orion Web Console, you can use NPM to monitor CPU, memory, and other critical resources utilized by LEM. Complete the steps in this topic to configure LEM to communicate with NPM.

As of version 6.3.0, LEM can use SNMP version 3 to communicate with SolarWinds Network Performance Manager (NPM). Versions of LEM older than 6.3.0 can send SNMP traps to other devices when rules fire, but older LEM versions do not support sending health or status updates to other devices over SNMP.

Step 1: Enable the SNMP Request Service

See Send SNMP traps from LEM to other applications by turning on the SNMP Request Service for details. After you enable and configure the SNMP Request Service, go to the next step, "Set up the Orion Console for SNMP monitoring."

Step 2: Set up the Orion Console for SNMP monitoring

When you are finished enabling the SNMP Request Service, log in to the Orion Web Console and set up the LEM Manager as a monitored node on the Orion Platform.

  1. Log in to your Orion Web Console as an administrator.
  2. Navigate to Settings > Manage Nodes, and then click Add a Node.

    If the node already exists and it is not managed, click the node and select Not Managed Node > Yes to manage the node.

    The Define Node window displays.

  3. In the Polling Hostname or IP Address field, enter the IP address of the LEM Manager.

  4. Under Polling Method, select Most Devices: SNMP and ICMP.


  5. Select your polling method settings.


    1. Select SNMPv3 for the SNMP version.
    2. Enter the port number used to access SNMP on the LEM appliance.
    3. Under SNMPv3 Credentials, enter the user name used to access SNMP on the LEM appliance.

    4. Under SNMPv3 Authentication, enter the hashing algorithm method and password.

    5. Under SNMPv3 Privacy / Encryption, enter the communication encryption algorithm and password.

    6. Accept the default selections in the remaining options.

  6. To test the connection, click TEST.

    Test Successful displays if the connection is good.

  7. Click Next.

    Orion authenticates the LEM Manager and runs a discovery to locate the resources available to monitor on the LEM appliance. The discovered resources will list all of the elements that are available to monitor. Orion will automatically provide a list of selected resources based on the device type.

  8. In the Choose Resources window, select the resources to monitor on the node, and then click Next.
  9. In the Add Application Monitors window, click Next.
  10. In the Change Properties window, click Next.

  11. Click OK, Add Node.

    The LEM appliance is added to the Orion Web Console for monitoring.

Troubleshooting your Orion connection

If you cannot establish a connection between your LEM appliance and the Orion Platform:

  • Ensure that the settings you entered in the Define Node window match the settings used to enable the SNMP Request Service.
  • Review the Orion logs located at c:\ProgramData\SolarWinds\Discovery for errors.

See Unable to add nodes through the Web Console for additional troubleshooting information.
