I don't think it's possible. If there is option for extracting via CLI / REST / etc any metrics that will help you understand state of those processes that you should be able to write proper OneAgent / Active Gate plugin that will help.
It should not be issue if they are available, you can post an RFE for this. For now it may be quicker to develop own OneAgent plugin for this case. Main difference will be there that your own plugin will consume custom metrics, dynatrace one works for free.
