=head1 MODE

Check datacenter alarms (red an yellow).

=over 8

=item B<--datacenter>

Datacenter to check.
If not set, we check all datacenters.

=item B<--filter>

Datacenter is a regexp.

=item B<--filter-time>

Don't check alarm older (value in seconds).

=item B<--memory>

Check new alarms only.

=item B<--warning-status>

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

=item B<--critical-status>

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

=item B<--warning-*>

Threshold warning.
Can be: 'total-alarm-warning', 'total-alarm-critical'.

=item B<--critical-*>

Threshold critical.
Can be: 'total-alarm-warning', 'total-alarm-critical'.

=head1 MODE

Check datacenter alarms (red an yellow).

=over 8

=item B<--datacenter>

Datacenter to check.
If not set, we check all datacenters.

=item B<--exclude-type>

Exclude alarms of specified type(s). Can be a regex.

Can be for example: --exclude-type='HostSystem' will not show HostSystem alarms.

=item B<--filter>

Datacenter is a regexp.

=item B<--filter-time>

Do not check alarms older than specified time (value in seconds).

=item B<--filter-type>

Check only alarms for specified type(s). Can be a regex.

Can be for example: --filter-type='VirtualMachine' will only show alarms for VirtualMachines. 

=item B<--memory>

Check new alarms only.

=item B<--warning-status>

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

=item B<--critical-status>

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

=item B<--warning-*>

Threshold warning.
Can be: 'total-alarm-warning', 'total-alarm-critical'.

=item B<--critical-*>

Threshold critical.
Can be: 'total-alarm-warning', 'total-alarm-critical'.
