=head1 MODE

Check cluster nodes.

=over 8

=item B<--filter-counters>

Only display some counters (regexp can be used).
Example: --filter-counters='node-status'

=item B<--cluster-id>

Which cluster to check (Default: 'me').

=item B<--filter-node-id>

Filter nodes by node id (can be a regexp).

=item B<--unknown-node-status>

Set unknown threshold for status.
Can used special variables like: %{status}, %{ip_address}, %{id}

=item B<--warning-node-status>

Set warning threshold for status.
Can used special variables like: %{status}, %{ip_address}, %{id}

=item B<--critical-node-status>

Set critical threshold for status (Default: '%{status} !~ /ok/i').
Can used special variables like: %{status}, %{ip_address}, %{id}

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

Thresholds.
Can be: 'cluster-nodes-total', 'cluster-nodes-ok'.
