OneAgent - Hibernation

[Rich]

As part of our migration of applications into the cloud, we have come across a strange problem.

One of our application teams is deploying "auto scaling" within AWS, it builds 4 servers and puts 2 servers into "hibernation" when not needed then they auto "wake" on demand when required.

When this happens, the OneAgent disconnects from all the previously injected processes which stops deep level monitoring. We would then be forced to restart the processes for the one-agent to inject back in. This is not practical as restarting these processes causes application impact.

Is there any workaround for this?

The fundamentals of Dynatrace include that injectable processes will need to be restarted/recycled in order to inject. If the 2 servers sleeping, I'm assuming they are turned off, then upon start up those processes might need to be recycled, I would recommend making those segments part of the start up script. 

The only other way around this is to leverage a monitoring mode that doesn't need recycling which in turn wont do injection. That would be discovery, and infrastructure mode.
