Custom OneAgent healthcheck plugin | oneagentctl --healthcheck

[Romanenkov_Al3x]

Hello everyone!

Maybe this plugin will be useful, especially in large organizations when the right hand does not know what the left hand is doing.  At the same time monitoring is critical too.

Great use case: when somebody from the security team or the Ops team changes the capabilities and rights to the Dynatrace OneAgent folder without having any idea - how it will affect the system, just execute his own internal instructions & restrictions.

Very good job.

Is this developed by Dynatrace or customer?  Located on https://www.dynatrace.com/hub/?filter=all?

[Romanenkov_Al3x]

Thanks. This is developed by me.

It was an interesting task. I'm glad to be able to share some results here.

To post in the hub, I think I need to finish windows, but unfortunately, I have a huge number of projects and other work.
