I am a newbie with this check plugin, so forgive me if I ask an FAQ (I couldn't google it):

I am trying to write checks for a device giving me this:

I now try to define separate checks for CPUs, Interfaces etc and also want to check the disk-usage.

How to specify the separate disks?

I fail with:


# /usr/lib/nagios/plugins/check_nwc_health  --hostname 10.0.0.134 --community secret42 --mode disk-usage  STORAGE_37  -vvvvv
[DISKSUBSYSTEM]
info: checking disks

UNKNOWN - no disks

# /usr/lib/nagios/plugins/check_nwc_health  --hostname 10.0.0.134 --community secret42 --mode disk-usage   -vvvvv

pls advise, thanks

Irgendwo da drin kommt was mit --blacklist vor, damit geht das, allerdings absolut umständlich, da man alles, was man nicht sehen will, blacklisten muss. Ansonsten ist es nicht möglich und vorgesehen, einzelne Komponenten getrennt zu überwachen.

thx. Ich werde gezielt einzelne SNMP-Checks schreiben.
