Issue/Introduction

The message "FATAL: Failed to find gpmmon executable: /usr/local/greenplum-db-6.21.1/bin/gpmmon (gpmmon packet version 5 )" appears very often in the master log.

This message is reported when the cluster is configured to run "gpperfmon" processes.
These processes were used for the older Greenplum Command Center (GPCC) versions.
It is not needed and should be disabled when running GPCC 6.x and above.

Environment

Product Version: 6.21

Resolution

Fix:

Set gp_enable_gpperfmon to off

gpconfig -c gp_enable_gpperfmon -v off

Then restart the database for the parameter change to take effect.

gpstop -af
gpstart -a
