Hi, what 3rd party for example do you refer to?
The PM code already exists at engine,
And you're also using quartz for scheduling.
Yair,
You're are raising some good points, but imo the entire host monitoring (inc
getVdsStats, etc.) should be externalized.
There are 2 major issues that we still don't cover:
- No HA for monitoring, who checks the hosts when the engine is down.
- No scale - the engine is a bottle-neck in network and compute.
Although the above is a huge arch change, we need to start somewhere, this feature sounds
like a candidate to introduce it.
About the examples:

The main goal of the feature if my suggestion is taken, is to select to most appropriate
one.
Thanks,
Gilad.
