When bringing down a monitored MySQL server, stop the agent first, to avoid generating a misleading “Server is unreachable” event.
For instance, if you stop the server to do a backup, follow these steps:
Stop the agent.
Stop the service/daemon.
Perform the backup.
Restart the service/daemon.
Restart the agent.
To stop or start the agent, see:
To stop the MySQL service/daemon, see the MySQL reference manual for your server version, on the web site http://dev.mysql.com/doc.
Or, to blackout all events associated with a specific server or group of servers, see Section 4.4, “Advisor Blackout Periods”.
