=item B<--component>
|
|
|
|
Which component to check (Default: '.*').
|
|
Can be: 'xxx', 'yyy'.
|
|
|
|
=item B<--filter>
|
|
|
|
Exclude some parts (comma seperated list) (Example: --filter=xxx --filter=yyyy)
|
|
Can also exclude specific instance: --filter=xxxxx,instancevalue
|
|
|
|
=item B<--absent-problem>
|
|
|
|
Return an error if an entity is not 'present' (default is skipping) (comma seperated list)
|
|
Can be specific or global: --absent-problem=xxxx,instancevalue
|
|
|
|
=item B<--no-component>
|
|
|
|
Return an error if no compenents are checked.
|
|
If total (with skipped) is 0. (Default: 'critical' returns).

|
|
=item B<--threshold-overload>
|
|
|
|
Set to overload default threshold values (syntax: section,[instance,]status,regexp)
|

Example: --threshold-overload='xxxxx,CRITICAL,^(?!(normal)$)'
|
|
|
|
=item B<--warning>

|
|
Example: --warning='xxxxx,.*,30'
|
|
|
|
=item B<--critical>
|
|
|
|
Set critical threshold for temperatures (syntax: type,instance,threshold)
|
|
Example: --critical='xxxxx,.*,40'
|
|
|
|
=item B<--warning-count-xxxx>
|
|
|
|
Set warning threshold for component count.
|
|
|
|
=item B<--critical-count-xxxx>
