|
-m, --memory=WARN,CRIT
|

|
|
|
|
|
-S (--ServiceId) Oreon Service Id
|
|
|
|
|
|
|
|
|
|
Note :
|
|
|
|
|
CPU usage is in % of one cpu, so maximum can be 100% * number of CPU
|
|
|
|
|
example :
|
|
|
|
|
Browse process list : <script> -C <community> -H <host> -n <anything> -v
|
|
|
|
|
the -n option allows regexp in perl format :
|
|
|
|
|
All process of /opt/soft/bin : -n /opt/soft/bin/ -f
|

|
|
All 'named' process : -n named
