6.5.3 Starting/Stopping the Agent on Unix

When installation is finished, you can start the monitor agent from the command line by typing:

$> /opt/mysql/enterprise/agent/etc/init.d/mysql-monitor-agent start

For a non-root installation the command would be:

$> /home/<user name>/mysql/enterprise/agent/etc/init.d/mysql-monitor-agent start

To stop the agent, use the stop command:

$> ./mysql-monitor-agent stop

If the agent cannot be stopped because the pid file that contains the agent's process ID cannot be found, you can use kill to send a TERM signal to the running process:

$> kill -TERM PID

To verify that the agent is running, use the following command:

$> ./mysql-monitor-agent status

The resulting message indicates whether the agent is running. If the agent is not running, use the following command to view the last ten entries in the general Agent log file:

$> tail /opt/mysql/enterprise/agent/logs/mysql-monitor-agent.log

For further information on troubleshooting the agent, see Section 6.10, “Troubleshooting the Agent”.

Installation creates the directory /opt/mysql/enterprise/agent, with the logs directory is located immediately below the agent directory.

To see all the command-line options available when running the monitor agent, navigate to the /opt/mysql/enterprise/agent/etc/init.d directory and execute mysql-monitor-agent help, which displays the usage message:

$> ./mysql-monitor-agent {start|stop|restart|status}

To report its findings, the agent connects to the Monitor UI through the port specified during installation. The default value for this port is 18443; ensure that this port is not blocked. To troubleshoot the agent installation, see Section 6.10, “Troubleshooting the Agent”.
