+ --username
+ the mysql db user
+ --password
+ the mysql db user's password
+ --database
+ the database's name. (default: information_schema)
+ --warning
+ the warning range
+ --critical
+ the critical range
+ --mode
+ the mode of the plugin. select one of the following keywords:

+ "s\t(%s)\n";

+ }
+ printf "\n";
+ print <<EOUS;
+ --name
+ the name of something that needs to be further specified,
+ currently only used for sql statements
+ --name2
+ if name is a sql statement, this statement would appear in
+ the output and the performance data. This can be ugly, so
+ name2 can be used to appear instead.
+ --regexp
+ if this parameter is used, name will be interpreted as a
+ regular expression.
+ --units
+ one of %, KB, MB, GB. This is used for a better output of mode=sql
+ and for specifying thresholds for mode=tablespace-free
+
+ In mode sql you can url-encode the statement so you will not have to mess
+ around with special characters in your Nagios service definitions.
+ Instead of
+ --name="select count(*) from v\$session where status = 'ACTIVE'"
+ you can say
+ --name=select%20count%28%2A%29%20from%20v%24session%20where%20status%20%3D%20%27ACTIVE%27
+ For your convenience you can call check_mysql_health with the --mode encode
+ option and it will encode the standard input.
+
+ You can find the full documentation at
+ http://www.consol.de/opensource/nagios/check-mysql-health
