SNMP polling - AWS Elemental Conductor Live

SNMP polling

AWS Elemental Conductor Live generates SNMP traps for activity on the cluster. You can set up to poll the SNMP interface for messages. (If you prefer to receive traps, see SNMP polling.)

You can interact with Conductor Live using a variety of network management systems. AWS Elemental products ship with the Net-SNMP (http://www.net-snmp.org/) command line tools. These tools let you access the SNMP interface while you are logged into the system directly or over SSH. Examples in this document are given using net-snmp commands.

To set up SNMP polling

  1. Either disable the node firewall, or enable external access to SNMP interface.

    • For help disabling the firewall, see Configuring a firewall and opening ports.

    • External access to the SNMP interface is enabled by default. To check the setting, access the Settings page on the Conductor Live web interface and choose SNMP.

  2. Query either individual variables, or the entire SNMP interface.

    To query individual variables

    Use the Net-SNMP tools to query variables as follows.

    snmpget -c elemental_snmp -v2c -m <MIB> 
        localhost MIBvariable
    snmpget -c elemental_snmp -v2c -m ELEMENTAL-MIB 
          localhost serviceStatus

    For a list of MIBs and their variables, see MIBs in Conductor Live.

    To query the entire SNMP interface

    Use the Net-SNMP tools to do an snmpwalk to gather information about all of the running channels in the cluster.

    snmpwalk -c elemental_snmp -v2c -m ELEMENTAL-MIB:ELEMENTAL-CONDUCTOR-MIB localhost
