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.
