When trying to have OpsCenter remotely log into nodes and install the monitoring agent, there is no option to select which nodes you want the agent installed on.
For instance, I wanted to deploy the monitoring agent specifically to a server that I knew had been rebooted after the leap second change on Sunday morning. However, I have servers in my cluster that haven't been rebooted yet. If I could have selected which servers I wanted to deploy to, I wouldn't have had to go and reboot the servers or manually install the agent.
This is a very specific example but I think the ability to deploy selectively will let users benefit from the automation you guys have built while not having to worry about deploying something to their whole cluster that they haven't entirely vetted yet.
