[feedhenry-dev] Demostration video of Openshift SAR, Grafana and Prometheus in OpenShift

[David Martin]

Nice video Phil!

For anyone wondering about how the proxy stuff works,
we're using this application here https://github.com/openshift/oauth-proxy
It can sit in front of anything as a reverse proxy, providing
authentication (& authorisation  via a Subject Access Review request to
openshift).

It wasn't shown in this video, but the Prometheus Dashboard can also be
accessed via an oauth proxy.
Prometheus doesn't provide any auth at all, so the proxy provides a very
useful service on a publicly exposed route.


One other thing that wasn't shown in this video, but was alluded to (and
mentioned in a separate video. See
https://www.redhat.com/archives/feedhenry-dev/2017-November/msg00023.html)
was the service discovery mechanism prometheus used.
The fh-sync-server has a particular annotation, which proemthues looks for.
It then starts gathering metrics from the /metrics endpoint in
fh-sync-server.

WRT Grafana, although 2 default dashboards were included with it
(Promtetheus & fh-sync-server), the user is free to add their own
dashboards or tweak the existing ones.
