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.
This plugin executes the following commands against MySQL:
- "SHOW SLAVE STATUS [NONBLOCKING|NOLOCK]"
This plugin executes no UNIX commands that may need special privileges.
