You can configure a Greenplum system to trigger SNMP alerts or send email notifications to system administrators whenever certain database events occur.
Greenplum’s gpsnmpd agent is an SNMP (Simple Network Management Protocol) daemon that supports SNMP requests on the health and state of a Greenplum system by using a set of MIBs (Management Information Bases).
MIBs are a collection of objects that describe an SNMP-manageable entity — in this case, a Greenplum system. MIBs can be used by enterprise monitoring systems such
as IBM Tivoli, HP Openview, and Nagios to monitor our Greenplum system.
