triggering action in strategy when exporter finishes a task

[pmelange]

I need to be able to trigger an action in my strategy when the exporter is finished with a task.

Specifically, I have a DUT which has a completely quiet boot loader. By holding the reset button when powering on the DUT, it pulls an image per tftp. This is all working great, but I need to know when to release the reset button.

I need a way for the strategy to get notified that the tftp process has already begun. I can see that the tftp process has begun in "journalctl -f -u tftp-hpa.service".

Is there a way to have a strategy get a notification from the exporter so that it can do it's next step(s)?
