Enabling, Configuring, and Disabling SNMP Traps

  1. Before you enable SNMP traps, configure the trap receiver (Network Management System or SNMP server) with the Cloudera MIB.
  2. Do one of the following:
    • Select Clusters > Cloudera Management Service > Cloudera Management Service.
    • On the Home > Status tab, in Cloudera Management Service table, click the Cloudera Management Service link.
  3. Click the Configuration tab.
  4. Select Scope > Alert Publisher > SNMP.
  5. Select Category > SNMP
    • Enter the DNS name or IP address of the Network Management System (SNMP server) acting as the trap receiver in the SNMP NMS Hostname property.
    • In the SNMP Security Level property, select the version of SNMP you are using: SNMPv2, SNMPv3 without authentication and without privacy (noAuthNoPriv), or SNMPv3 with authentication and without privacy (authNoPriv) and specify the required properties:
      • SNMPv2 - SNMPv2 Community String.
      • SNMPv3 without authentication (noAuthNoPriv) - SNMP Server Engine Id and SNMP Security UserName.
      • SNMPv3 with authentication (authNoPriv) - SNMP Server Engine Id, SNMP Security UserName, SNMP Authentication Protocol, and SNMP Authentication Protocol Pass Phrase.
    • You can also change other settings such as the port, retry, or timeout values.

    If more than one role group applies to this configuration, edit the value for the appropriate role group. See Modifying Configuration Properties Using Cloudera Manager.

  6. Click Save Changes when you are done.
  7. Restart the Alert Publisher role.

To disable SNMP traps, remove the hostname from the SNMP NMS Hostname property (alert.snmp.server.hostname).
