DESCRIPTION

       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.

       If you want to run this check against the delayed slaves, e.g. those running with pt-
       slave-delay tool, you may want to specify -d option. It will not alert when
       Slave_IO_Running is Yes, Slave_SQL_Running is No and there are no errors.
