- We are running statsd exporter as an app with a public route for
Prometheus to scrape
- This updates preview to send statsd metrics over the CF internal
networking to the statsd exporter
- Removes the sidecar statsd exporters too
we saw an issue where the app started, then immediately crashed due to
a setup error. However, jenkins had already returned positively, and
the deploy continued.
cf-deploy should fail if the app doesn't start up.
We do this by looking through the cloudfoundry events, and aborting
if there are any `app.crash` events for the new GUID.
previously in run_app_paas.sh, we captured stdout from the app and
piped that into the log file. However, this came up with a bunch of
problems, mainly:
* exceptions with stack traces often weren't formatted properly,
and kibana could not parse them
* celery logs were duplicated - we'd collect both the json logs and
the human readable stdout logs.
instead, with the updated utils library, we can use that to log json
straight to the appropriate directory directly.
