> Runtime and total bytes metrics are not collected properly

> Key: BEAM-6100
> URL: https://issues.apache.org/jira/browse/BEAM-6100
> Project: Beam

> Priority: Major

>
> Currently, we collect time (distribution) and bytes (counter) metrics from
> one ParDo (called MetricsMonitor) that is put in pipelines in one,
> arbitrarily chosen place (usually "in the middle" of pipeline's graph. In
> some cases, invalid time (or total bytes count) is registered.
> Taking [this|https://github.com/apache/beam/pull/6987#discussion_r231976671]
> discussion into account, ideally, we'd like to:
> - collect runtime by recording time at the root and sink(s) of the pipeline
> - collect total bytes in a separate ParDo that allows deciding what byte
> amount do we actually want to collect (now it's coupled to the
> time-collecting Monitor which is inconvenient).
