Before you enable SNMP traps, make sure you have configured your trap receiver (Network Management System or SNMP server) with the Cloudera MIB.

To view the Cloudera MIB:

  1. From the All Services page, go to the Cloudera Manager management service.
  2. From the Configuration tab select View and Edit.
  3. Expand the Alert Publisher category in the Category list at the left, and select SNMP.
  4. In the Description column for the first property (SNMP NMS Hostname) there is a link to the SMNP MIB.
  5. Click the link in the Description field to view the MIB.

To enable, disable, or configure SNMP traps:

  1. From the Services tab, select the Cloudera Management Services service instance.
  2. Pull down the Configuration tab and click Edit.
  3. Under the Alert Publisher (Base) role group select SNMP to see the list of properties.
    • 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.
    • Select the version of SNMP you are using: SNMPv2, SNMPv3 authentication with no privacy (authNoPriv), or SNMPv3 with no authentication and no privacy (noAuthNoPriv).
    • For SNMPv2, you must enter a Community String.
    • For SNMPv3, you must enter the SNMP Server Engine ID.
    • For SNMPv3 with authentication (authNoPriv) you must also enter the Security user name, Authentication protocol, and protocol pass phrase.
    • You can also change other settings such as the port, retry, or timeout values.
  4. Click Save Changes when you are done.
  5. You must restart the Alert Publisher role to have these changes take effect.

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