The simply_fast processes monitor nodes in the vertica cluster on behalf of the Management Console (MC). If you are not using MC, you can safely stop it. As root (on each cluster node): # service vertica_agent stop To disable the agent from restarting on a server reboot, use chkconfig: # chkconfig --del vertica_agent Reverse these steps with: # chkconfig --add vertica_agent # service vertica_agent start
