Subject Re: Getting statistics from Mesos to plot usage and allocation per Framework.
Date Thu, 06 Aug 2015 10:42:31 GMT
Sorry, I could not understand this sentence:
"""
When polling the metrics/snapshot, in my case when running short
sub-second tasks, I have to poll even faster than the churn time of tasks
to get an accurate picture of resource allocation.
"""
Could you explain more?
