Is it possible to add a host to a hostgroup where both are previously existing via the API? Say I have host_1 through host_1000 and I want to add them all to hostgroup_3 via the API, can I do that?

Also, is there a way to adjust check_interval values via the API? I tried to modify the value for all hosts in a hostgroup but it corrupted the configs and wouldn't let me apply.

Hello, @andrewatmacys. You can submit an API command to add a new hostgroup, but specify the same hostgorup name. That way the command is going to override the existing hostgroup definition and will allow you to add new hosts.

curl -XPOST "http://192.168.3.3/nagiosxi/api/v1/conf ... y&pretty=1" -d "hostgroup_name=testapihostgroup&alias=HostGroup&members=host1&applyconfig=1" -k -L

curl -XPOST "http://192.168.3.3/nagiosxi/api/v1/conf ... y&pretty=1" -d "hostgroup_name=testapihostgroup&alias=HostGroup&members=host1,host2,host3,...,host100&applyconfig=1" -k -L

Same applies to overiding host configs with API commands. I don't think you can bulk modify all hosts in a hostgroup with an API command. Can you show me how you tried doing that?

The bulk modification was a separate event, I should have clarified that from the start, my mistake.

So I would have to individually list every host we wanted to modify in the case of the check_interval setting?

Via the API yes.

Or you can change settings in bulk via
CCM -> Bulk Modifications Tool
