Replace hostgroup on 100's of hosts

[ottow]

Hi,

We are expanding our deployment of mod_gearman workers and need to switch several 100s of hosts to a new worker.
To do this, we need to remove a mg_objects_ hostgroup currently set on each host (not inherited) and add a new, different mg_objects hostgroup.

What would be the easiest way to do this?
We've looked at using the Bulk Modifications Tool, but it is really cumbersome to remove a hostgroup from large numbers of individual hosts using it....

Is there a better solution?

Hi @ottow,

The other solution would be to script this out using the API, see the PUT config/hostgroup/<hostgroup_name> endpoint. If this something you commonly do, then it makes sense to take a little more time to do this programitcally. One caveat, that endpoint will overwrite the entire host group, you cannot append a single member to the hostgroup using the PUT option.

Otherwise, the Remove Host Group in the Bulk Mods Tool is probably the best choice.

Regards,
Benjamin
