As for regression detection, we have a Jenkins job
beam_PerformanceTests_Analysis
<https://builds.apache.org/view/A-D/view/Beam/view/All/job/beam_PerformanceTests_Analysis/>
which
analyzes metrics on Bigquery and report a summary to job console output.
However, not all jobs are registered on this analyzer and currently no
further alerts integrated with it (e.g. email / slack).

There are ongoing work to add alerting to benchmarks. Kasia and Kamil are
investigating on Prometheus + Grafana, and Manisha and me are looking into
mako.dev.
