The API is a growing thing. At this time, I don't think modifying host groups is in the code. I'd like to see it though, so I am looking forward to the reply from Nagios.

Adding a new host to an old hostgroup can be easily done via the REST API, but there is one thing that you need to keep in mind. It's not a "modification" of the hostgroup config... It's more like "recreating it from scratch" if this makes any sense. If you have any existing hostgroup members, you must "re-add" them, along with the new member (the host you created).

Here's an example. I added a testapihost via the REST API simply by copying/pasting the command from the "REST API - Config Reference" section under the Help menu. Next I added this host to an existing hostgroup I have.

The hostgroup's config prior to adding the host:

Code: Select all

define hostgroup {
    hostgroup_name    sensors
    alias             Sensors
    members           AKCP SensorProbe2,EM08T
}

To add the new member to the "Sensors" hostgotup (the "testapihost" host), I ran:

Code: Select all

[root@main-nagios-xi ~]# curl -XPOST "http://x.x.x.x/nagiosxi/api/v1/config/hostgroup?apikey=LTltbjobR0X3V5ViDIitYaI8hjsjoFBaOcWYukamF7oAsD8lhJRvSPWq8I3PjTf7&pretty=1" -d "hostgroup_name=sensors&alias=Sensors&members=AKCP SensorProbe2,EM08T,testapihost&force=1&applyconfig=1"
{
    "success": "Successfully added sensors to the system. Config applied, Nagios Core was restarted."
}

The hostgroup's config after adding the host:

Code: Select all

define hostgroup {
    hostgroup_name    sensors
    alias             Sensors
    members           AKCP SensorProbe2,EM08T,testapihost
}

Now, the old "sensors" group has 3 members:

Hope this helps.
