Couple of use cases, I have metric representing job version, currently it bound for a task, but I want bound it to job manager, another example I have dump to on OOM exception configured, and on start, I want to check content of directory with dumps and if not empty increase restarted-due-to-OOM counter

Hi Alexey,

could you describe what you want to achieve? Most metrics are bound to a specific task (available in RuntimeContext). You can also access them in custom operators and state backends.

Then you have some metrics bound to taskmanager and even java processes, but I don't see an easy way to access them.

I'm also pulling in Chesnay; he can probably help you more (but I guess we really need to understand your need).

Hello,

Is it possible to register user metric outside task/operator (not in RichMapFunction#open)

Thanks,
Alexey
