=item B<--component>
|
|
|
|
Which component to check (Default: '.*').
|
|
Can be: 'sensor'.
|
|
|
|
=item B<--filter>
|
|
|
|
Exclude some parts (comma seperated list)
|
|
Can also exclude specific instance: --filter=sensor,celsius.*
|
|
|
|
=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)
|
|
It used before default thresholds (order stays).
|
|
Example: --threshold-overload='sensor.celsius,OK,nonoperational'
|
|
|
|
=item B<--warning>
|
|
|
|
Set warning threshold (syntax: type,regexp,threshold)
|
|
Example: --warning='sensor.celsius,.*,30'
|
|
|
|
=item B<--critical>
|
|
|
|
Set critical threshold (syntax: type,regexp,threshold)
|
|
Example: --critical='sensor.celsius,.*,40'
|
|
|
|
=item B<--sensor-scale>
|
|
|
|
Apply scaling value (some equipments are buggy. So we don't use scale by default).
