Okay, this might have been because those nodes got preempted very very quickly. It looks like none of them lasted more than a minute before they got preempted.

Hmm no, even after turning off preemption, it still launched two nodes:
even though the instance cap is set to 1. This looks to be a pretty bad bug.

My experience says that it works with roughly good precision..
We have it set for 50 instances and max I saw was 52..
Issue is that we are starting new instances and they are not counted until they will start showing on listing.. which may take few seconds..
I dont think its worth making it more precise, because it will make it slower/more complicated..

@hach-que I don't know if it's worth it as stated above to make it more precise. What are your thoughts? Is this a significant problem for your use case? Looking at the code, it seems it could be a timing issue between having to terminate the instance and then provisioning new instances.

In my case I'm launching 32-core Windows instances, with an instance cap of 1. So when it goes over it effectively doubles my spend on Google Cloud. For 32-core Windows instances, that's not trivial given the premium OS licensing per core.

I see, yes, the cost can really add up. I'll have to research further into this since this could involve a pretty significant code change.

With #99 recently, it seems it'll be difficult to change the timing parameters such as the following:
-Dhudson.slaves.NodeProvisioner.initialDelay=0 -Dhudson.slaves.NodeProvisioner.MARGIN=50 -Dhudson.slaves.NodeProvisioner.MARGIN0=0.85 -Dhudson.model.LoadStatistics.clock=10000 -Dhudson.model.LoadStatistics.decay=0.2
They need to be passed through Java. Only thing I can recommend temporarily is you'd have to have your own local build of the plugin with altered values for those above parameters?
