Subject Way to get accumulators values *during* job execution ?
Date Wed, 02 Dec 2015 16:21:28 GMT

I use Grafana/Graphite to monitor my applications. The Flink GUI is really nice, but it disappears
after the job completes and consequently is not suitable to long-term monitoring.

For batch applications, I simply send the accumulator’s values at the end of the job to
my Graphite base.
For streaming applications, it’s more complex as the job never ends. It would be nice to
have a way of getting current accumulator values (like in the GUI)  to push it periodically
to Graphite in a monitoring thread. Is there any API to get the values during execution ?

Best regards,
