The system metrics [1] are only available on a system level, i.e. not for an individual job. The reason is that multiple job might run concurrently on the same task manager JVM process. So it would not be possible to separate their heap usage. The same would be true for the approach that monitors the task manager tmp directory.
You would need to correlate your measurements with the time range in which a job is executed.
