For some others hosts type who need snmp, I run this command with the parameter that Wessley adice and now we didn’t still have the issue:
edit_host&request_format=python -d ‘request={“hostname”:“my-snmp-host”,“attributes”:{“tag_snmp_ds”:“snmp-v2”,“snmp_community”:“xxxx”}}’
And after apply changes, the Wato now work for these snmp hosts.
