Check linux processes.
Can filter on commands, arguments and states.
=over 8
=item B<--remote>
Execute command remotely in 'ssh'.
=item B<--hostname>
Hostname to query (need --remote).
=item B<--ssh-option>
Specify multiple options like the user (example: --ssh-option='-l=centreon-engine' --ssh-option='-p=52').
=item B<--ssh-path>
Specify ssh command path (default: none)
=item B<--ssh-command>
Specify ssh command (default: 'ssh'). Useful to use 'plink'.
=item B<--timeout>
Timeout in seconds for the command (Default: 30).
=item B<--sudo>
Use 'sudo' to execute the command.
=item B<--command>
Command to get information (Default: 'ps').
Can be changed if you have output in a file.
=item B<--command-path>
Command path (Default: none).
=item B<--command-options>
Command options (Default: '-e -o state -o ===%t===%p===%P=== -o comm:50 -o ===%a -w 2>&1').
=item B<--warning>
Threshold warning (in absolute of processes count. After filters).
=item B<--critical>
Threshold critical (in absolute of processes count. After filters).
=item B<--warning-time>
Threshold warning (in seconds).
On each processes filtered.
=item B<--critical-time>
Threshold critical (in seconds).
On each processes filtered.
=item B<--filter-command>
Filter process commands (regexp can be used).
=item B<--filter-arg>
Filter process arguments (regexp can be used).
=item B<--filter-ppid>
Filter process ppid (regexp can be used).
=item B<--filter-state>
Filter process states (regexp can be used).
You can use: 'zombie', 'dead', 'paging', 'stopped',
'InterrupibleSleep', 'running', 'UninterrupibleSleep'.
