OpenCensus, custom metrics and Apache Beam

[Davide Anastasia <da...@cloud-iq.com>]

Hi all,
I am trying a few business-driven metrics into my streaming pipelines
(running on Dataflow). These metrics will be published to Stackdriver, and
I have initially tried using the google-cloud-monitoring API directly.
However I have hit an hard problem with out-of-order materialisation of
different windows (I have explained more or less my problem here:
https://stackoverflow.com/questions/53691263/trigger-windows-in-order-in-apache-beam
) so I thought of giving a go to OpenCensus.

What I am trying to do is a simple Meter metrics (req/min, for instance),
but I cannot get OpenCensus to talk to Stackdriver.

I wonder if anybody tried to do something similar and wants to share
his/her experience.

Thanks,
Davide
