About Management and Monitoring Utilities

Greenplum Database provides standard command-line utilities for performing common monitoring and administration tasks.

Greenplum command-line utilities are located in the $GPHOME/bin directory and are executed on the master host. Greenplum provides utilities for the following administration tasks:

  • Installing Greenplum Database on an array
  • Initializing a Greenplum Database System
  • Starting and stopping Greenplum Database
  • Adding or removing a host
  • Expanding the array and redistributing tables among new segments
  • Managing recovery for failed segment instances
  • Managing failover and recovery for a failed master instance
  • Backing up and restoring a database (in parallel)
  • Loading data in parallel
  • Transferring data between Greenplum databases
  • System state reporting

Greenplum Database includes an optional performance management database that contains query status information and system metrics. The gpperfmon_install management utility creates the database, named gpperfmon, and enables data collection agents that execute on the Greenplum Database master and segment hosts. Data collection agents on the segment hosts collect query status from the segments, as well as system metrics such as CPU and memory utilization. An agent on the master host periodically (typically every 15 seconds) retrieves the data from the segment host agents and updates the gpperfmon database. Users can query the gpperfmon database to see the query and system metrics.

Pivotal provides an optional system monitoring and management tool, VMware Tanzu Greenplum Command Center, which administrators can install and enable with VMware Tanzu Greenplum. Greenplum Command Center provides a web-based user interface for viewing system metrics and allows administrators to perform additional system management tasks. For more information about Greenplum Command Center, see the Greenplum Command Center documentation.
