Check processes.

=over 8

=item B<--filter-name>

Filter processes by name (can be a regexp).

name is the following concatenation: type:group (eg.: EXTRACT:DB_test)

=item B<--filter-group>

Filter processes by group (can be a regexp).

=item B<--filter-type>

Filter processes by type (can be a regexp).

=item B<--unknown-status>

Set unknown threshold for status.
Can used special variables like: %{status}, %{name}, %{group}, %{type}

=item B<--warning-status>

Set warning threshold for status.
Can used special variables like: %{status}, %{name}, %{group}, %{type}

=item B<--critical-status>

Set critical threshold for status (Default: '%{status} =~ /ABENDED/i').
Can used special variables like: %{status}, %{name}, %{group}, %{type}

=item B<--warning-*> B<--critical-*>

Thresholds.
Can be:  'lag' (s), 'time-checkpoint' (s).
