Subject Re: Flink heap memory
Date Tue, 30 Apr 2019 06:04:58 GMT
Hi Rad,

the heap memory can only measured on a the JVM (Taskmanager/Jobmanager)
level. If you have multiple jobs running in the same cluster, you can not
separate their memory footprint easily unless you you only run Taskmanagers
with a single Taskslot, so that one Taskmanager is always only executing a
single job.

For the per JVM metrics, please check out this blogpost or the
documentation [1,2] as a starting point.

Best,

Konstantin
