Custom metrics in Stateful Functions

[Cliff Resnick]

We think Embedded Statefun is a nicer fit than Datastream for some problem domains, but one thing we miss is support for custom metrics/counters. Is there a way to access the Flink support? It looks like if we want custom metrics we'll need to roll our own.

Hello Cliff,

You are right, indeed defining custom metrics is not supported at the moment.

I will file a JIRA issue so we can track this, and we will try to prioritize this feature up.

Meanwhile, there are a lot of metrics that StateFun defines, like invocations rates etc' perhaps you can find it useful already [1]

Kind regards,

Igal.
