Simple Network Management Protocol (SNMP) polling

Rather than passively receiving SNMP traps from AWS Elemental Live, you can actively poll the SNMP interface.

You can interact with Elemental Live using a variety of network management systems. AWS Elemental products ship with the Net-SNMP (http://www.net-snmp.org/) command line tools to access the SNMP interface while 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 Open ports on the firewall for Elemental Live nodes.

   • External access to the SNMP interface is enabled by default. To check the setting, access the Settings page on the Elemental 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 Management Information Bases (MIBs) in Elemental 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.

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