SNMP checks not working

[tmnguyen (Minh Tuan Nguyen)]

Hi everyone

We have issues with our SNMP monitor. None of the hosts with snmp monitored works. It only shows Check_MK HW/SW Inventory
Our version is 1.5.0p11

It seems the issue happen when we upgrade from 1.4 to 1.5

Any help is appreciate.

Thanks,
Louis

Did you customize the tag group “Agent Type” in 1.4?
What is the current status of the Data Source configuration settings of the affected hosts?

Regarding tag group agent type, I’m not sure where it is setup as I am new to checkmk.

Thank you.

but make a test on the consol with cmk -i

look here:

HW/SW-Inventur über die Konsole

Hallo, mit der Option -i oder --inventory kannst du das dem cmk Befehl mitgeben. Über -v kannst du dazu auch den verbosen Modus einschalten. -i, --inventory Does a HW/SW-Inventory for all, one or several hosts. If you add the option -f, --force then persisted sections will be used even if they are outdated.

When I tried on CLI with cmk -vI command on the host:

• FETCHING DATA
  [snmp] Execute data source
  [snmp] ERROR: too many values to unpack
  [piggyback] Execute data source
• EXECUTING DISCOVERY PLUGINS (0)
  SUCCESS - Found nothing new

I also tried to create a new site with same version, it works fine.
So, there’s something wrong with current site but I don’t know where yet.
