the mode of the plugin. select one of the following keywords:

my $longest = length ((reverse sort {length $a <=> length $b} map { $_->[1] } @modes)[0]);
204
(length ((reverse sort {length $a <=> length $b} map { $_->[1] } @modes)[0])).
207
printf $format, $_->[1], $_->[3];
212
the name of something that needs to be further specified,
213
currently only used for sql statements
215
if name is a sql statement, this statement would appear in
216
the output and the performance data. This can be ugly, so
217
name2 can be used to appear instead.
219
if this parameter is used, name will be interpreted as a
222
one of %, KB, MB, GB. This is used for a better output of mode=sql
223
and for specifying thresholds for mode=tablespace-free
225
one of pnp4nagios (which is the default) or groundwork.
226
It is used to shorten performance data labels to 19 characters.
228
In mode sql you can url-encode the statement so you will not have to mess
229
around with special characters in your Nagios service definitions.

233
--name=select%20count%28%2A%29%20from%20v%24session%20where%20status%20%3D%20%27ACTIVE%27
234
For your convenience you can call check_mysql_health with the --mode encode
235
option and it will encode the standard input.
