Going by the list in the latest documentation <https://ci.apache.org/projects/flink/flink-docs-release-0.10/internals/monitoring_rest_api.html> for Flink 0.10.1 release, memory and cpu stats are not stored. Neither is the time spent on garbage collection stored anywhere.
In my opinion, trying to store these metrics will degrade the performance of jobs too. And so its basically a trade off between performance and computation cost. For me, the web ui hangs even for the current set of parameters :( *Ritesh Kumar Singh,* *https://riteshtoday.wordpress.com/* <https://riteshtoday.wordpress.com/> On Tue, Jan 26, 2016 at 7:16 PM, Pieter Hameete <phame...@gmail.com> wrote: > Hi people! > > A lot of metrics are gathered for each TaskManager every few seconds.
