Anyone know if it is possible yet to set a host group for the first time on OneAgents which currently exist without the need for reinstall? Thanks! ---

Hi Larry, You can use the OneAgent CLI that is located with the OneAgent.

Right, but I think that is only if you installed the OneAgent and called out a host group at that time. I am wondering if it is possible to now use that to configure a host group on OneAgents where host group was never used before without the need to reinstall. ---

I believe so, however this still requires an agent restart ---

Yes, you can set it via --set-host-group and there is even a convenient --restart-service you can add to do the stop/change/start of the oneagent service from a one liner, so it looks like this: ./oneagentctl --set-host-group EasyTravel\_WebServer\_Dev --restart-service ---

yes thats correct, you can but it will require a recycle of the oneagent process/Service FYI. Even if you did not define the host group at the time of install. ---
