check_generic -e <cmdline> -o|u|w|c <expression> [-f false state] [-n name] [-t timeout] [-r \\ 
check_generic [-h | --help]\\ 
check_generic [-V | --version]\\ 
''
=== -d, --tmpdir ===
specify directory for tmpfiles, default: /usr/tmp/check_generic
A garbage collection for files 'check_generic*' removes files 
older than 24 hours.

=== -e, --execute <cmdline> ===
A string which contains the commands to execute. This can be a complete command line including Unix filters. \\ The command string is executed via 'sh', this allows to use every valid shell command or every valid command chain.

=== --empty_output_is_ok ===
Normally //check_generic// will throw UNKNOWN if there is no output. If you want to avoid this, use the switch ''--empty_output_is_ok''.

=== -f, --false [u|UNKNOWN|w|WARNING|c|CRITICAL|o|OK] ===
which state the plugin should become if the expression is false
default: complement of state

=== -h, --help ===
print detailed help screen

=== --ignore_rc ===
If the executed program throws a RC other than 0 (OK), it will influence the overall result. If you want to avoid to include the RC into the result, use this switch.

=== --match_stderr ===
Use this switch, if also the STDERR output should be included in the input stream. The STDERR output will be appended to STDOUT before the regex matching.

=== -n, --name ===
plugin name (shown in output), default: empty

=== -p, --performance <string> ===
This is the performance tag which should describe the data.\\
Example: ''./check_generic -n nagios_services_latency -e "$USER1$/nagiostats -m -d AVGACTSVCLAT" -w ">30000" -c ">60000" -p "ms_average"
nagios_services_latency OK - result:67 match:none |**ms_average=67**
''
=== --print_match ===
If you specify a pattern match like -c '=~/foo (bar)/' you can enclose parts of the pattern with brackets. These parts will be used as output lateron.

=== -t, --timeout ===
timeout for one command, default: 10 
  
=== -u|w|c|o <expression> ===
=== --unknown,warning,critical,ok <expression> ===

This expression is just a normal PERL expression, e.g.
^Operator   ^ Meaning                      ^
| '= n'     | numerically equal            |
| '< n'     | numerically smaller than     |
| '> n'     | numerically larger than      |
| 'eq s'    | string equal                 |
| 'ne s'    | string not equal             |
| '=~/s/'   | regular expression matching  |
| '!~/s/'   | regular expression not matching |


=== -v, --verbose ===
Defines the verbosity, can be specified multiple times. Default: 0

=== -V, --version ===
Prints the version info

=== -y, --type <type>===
data type delta:
  - During the first call of the plugin the value is saved in a persistent file in the temporary directory.
  - During the second call the difference between the two values is divided by the number of the elapsed seconds:\\ ''result = (value2 - value1) / seconds''
