Hi Nick, I don't know if you have already come across the Rest Api. If not, please have a look here: https://ci.apache.org/projects/flink/flink-docs-master/internals/monitoring_rest_api.html
I know that Christian Kreutzfeldt (cc) has been working on a monitoring service which uses Akka messages to query the JobManager on a job's status and accumulators. I'm wondering if you two could engage in any way. Cheers, Max On Wed, Nov 11, 2015 at 6:44 PM, Nick Dimiduk <ndimi...@gmail.com> wrote: > Hello, > > I'm interested in exposing metrics from my UDFs.
