Flink heap memory

[Rad Rad]

Hi,

I would like to know the amount of heap memory currently used (in bytes) of
a specific job which runs on Flink cluster.

Regards.

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
