Set up SNMP monitoring on the Orion Web Console

You can configure SNMP version 3 on your LEM appliance to communicate with SolarWinds Network Performance Monitor (NPM) through ports 161 and 162. This configuration allows you to monitor CPU, memory, and other critical components from the SolarWinds Orion Web Console.

Enable the SNMP Request Service

To set up SNMP monitoring, enable the SNMP Request Service on the LEM appliance and record your settings.

  1. Open a connection to the LEM appliance management console using:

    • Vsphere console connection
    • Hyper-V console connection
    • PuTTY session on port 32022 as a cmc user
  2. At the cmc> prompt, enter service to access the Service menu.


  3. At the cmc::service> prompt, enter snmp.

    A message displays:

    cmc::service > snmp
    SNMP??Trap Logging Service is DISABLED
    Would you like to ENABLE the SNMP Trap Logging Service? [Y/n]
  4. Enter n to disable the SNMP Trap Logging Service.

    A message displays:

    cmc::service > snmp
    SNMP??Request Service is DISABLED
    Would you like to ENABLE??the SNMP Request Service? [Y/n]
  5. Enter Y to enable the SNMP Request Service.
  6. Enter and record the following information at the prompts:

    • Port number and user name to access SNMP on the LEM appliance
    • Password hashing algorithm (SHA1, MD5, or NO authentication)
    • Authentication password
    • Communication encryption algorithm (AES128, DES56, or NO encryption)
    • Encryption key

    You will need these settings to set up the Orion Console for SNMP monitoring.

    The SNMP Request Service is started on the LEM appliance.

  7. Exit the management console.

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. Click Settings > Manage Nodes, and then click Add a Node.

    If the node already exists and is not managed, click the node and select Not Managed Node > Yes, 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. Click TEST to test the connection.

    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 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.
