Send SNMP traps from SEM to other applications

Turn on the SNMP Request Service to allow SEM to output SNMP traps to one or more applications on your network. SEM supports SNMP version 2 and SNMP version 3.

The SNMP Request Service must be turned on in SEM to do the following:

  • Send SNMP traps to devices when SEM rules fire
  • Use NPM and the SolarWinds Orion Web Console to monitor SEM system resources such as CPU and memory

If you use SolarWinds Network Performance Monitor (NPM) in your environment:

  1. Enable the SNMP Request Service using the steps on this page.
  2. To set up the Orion Console for SNMP monitoring, see Monitor SEM from NPM and the Orion Web Console using SNMP.

To enable or disable the SNMP Request Service

  1. Open the CMC command line.

    See Log in to the SEM CMC command line interface for instructions.

  2. At the cmc> prompt, type:

    service

  3. At the cmc::service> prompt type:

    snmp

    A prompt like the following appears:

    SNMP Trap Logging Service is DISABLED
Would you like to ENABLE the SNMP Trap Logging Service? [Y/n]

    The SNMP Trap Logging Service is not the same as the SNMP Request Service. The SEM SNMP Trap Logging Service receives SNMP traps from other devices, whereas the SEM SNMP Request Service outputs SNMP traps outside of SEM. See Enable SEM to receive SNMP traps for more information.

  4. Do not change the status of this service unless you know what you are doing.

    To go to the next step, type Y or n, and then press Enter.

    A prompt like the following appears:

    SNMP Request Service is DISABLED
Would you like to ENABLE the SNMP Request Service? [Y/n]

  5. To enable or disable the service, type Y or n, and then press Enter.

    If you enabled the SNMP Request Service, the following prompt appears:

    Enter the port number to access SNMP on SEM (default: 161):

  6. Type the port number that SEM should use to communicate with SolarWinds Network Performance Monitor (NPM), and then press Enter.

    Ports 161 and 162 are standard.

    The following prompt appears:

    Enter the username to access SNMP on SEM (default: orion):

  7. Type the user name to use, and then press Enter.

    The following prompt appears:

    Enter the password hashing algorithm (SHA1, MD5 or NO for no authentication, default: SHA1):

  8. Enter an option, and then press Enter.

    The following prompt appears:

    Enter the authentication password (default: orion123):

  9. Type the password, and then press Enter.

    The following prompt appears:

    Enter the communication encryption algorithm (AES128, DES56 or NO for no encryption, default: AES128):

  10. Enter an option, and then press Enter.

    The following prompt appears:

    Enter the encryption key (default: orion123):

  11. Type the encryption key, and then press Enter.

    The SNMP Request Service is started.

  12. To return to the main menu, type exit at the cmc::service> prompt.

  13. To log out and close the CMC command-line, type exit again.
