This Nagios plugin examines whether replication is running. It is separate from the check for delay because it is confusing or impossible to handle all of the combinations of replication errors and delays correctly, and provide an appropriate type of alert, in a single program.
By default, this plugin treats it as critical when the either thread stops with an error, and a warning when threads are stopped with no error. You can provide critical and warning thresholds with the -c and -w options, for compatibility with Nagios plugin conventions, but they don’t work as thresholds. Instead, if you specify a critical threshold, this plugin will treat it as critical if either thread is stopped, with or without an error.
The warning threshold makes the plugin report a warning when SHOW SLAVE STATUS produces no output, which means it is not configured as a replica. By default, this plugin will report that replication is healthy when a server isn’t configured as a replica.
This plugin executes the following commands against MySQL:
This plugin executes no UNIX commands that may need special privileges.
