Options:
--connect
the connect string
--username
the oracle user
--password
the oracle user's password
--warning
the warning range
--critical
the critical range
--mode
the mode of the plugin. select one of the following keywords:

my $format = " %-".
(length ((reverse sort {length $a <=> length $b} map { $_->[1] } @modes)[0])).
"s\t(%s)\n";
foreach (@modes) {
printf $format, $_->[1], $_->[3];
}
printf "\n";
print <
the name of the tablespace, datafile, wait event,
latch, enqueue, or sql statement depending on the mode.
--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
Tablespace-related modes check all tablespaces in one run by default.
If only a single tablespace should be checked, use the --name parameter.
The same applies to datafile-related modes.
tablespace-remaining-time will take historical data into account. The number
of days in the past can be given with the --lookback parameter. (Default: 30)
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_oracle_health with the --encode
option and it will encode the standard input.

Options:
--connect

the critical range
--mode
the mode of the plugin. select one of the following keywords:

foreach (@modes) {
printf $format, $_->[1], $_->[3];
}
printf "\n";
print <
the name of the tablespace, datafile, wait event,
latch, enqueue, or sql statement depending on the mode.
--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
Tablespace-related modes check all tablespaces in one run by default.
If only a single tablespace should be checked, use the --name parameter.
The same applies to datafile-related modes.
tablespace-remaining-time will take historical data into account. The number
of days in the past can be given with the --lookback parameter. (Default: 30)
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_oracle_health with the --encode
option and it will encode the standard input.
