Eigener SNMP Check: UNKN - Item not found in SNMP data

Moin,

ich habe die Tabs einmal entfernt und ich auch wenig gespielt. Im Iventory habe ich das gewünschte Ergebnis.

OMD[clage]:~/local/share/check_mk/checks$ cmk -v -II XXXXXX
Discovering services on: XXXXXX
XXXXXX:
+ FETCHING DATA
 [snmp] Execute data source
+ EXECUTING DISCOVERY PLUGINS (8)
  1 hr_cpu
  1 hr_mem
  2 if_lancom
  1 lancomwlc
  1 snmp_info
  1 snmp_uptime

Wenn ich über WATO suche, dann steht er direkt unten drin, allerdings mit einem UNKN Status…

Hier noch einmal der komplette Check:

Vermutlich ist es total offensichtlich und ich sehe den Baum vor lauter Bäumen nicht…
