[Hawkular-dev] OpenShift - An error occurred getting metrics.

[Anton]

I thought that the problem might be wtih how my domain name is configured,
so I set up a CNAME record to point to the ip of my cluster, but this still
did not work.

It seems something internally is not working internally with regards to the
routing/dns to the hawkular-metrics service.

To eleborate, I created a new route, to hawkular-metrics, and this new
route DOES work.

So I deleted the originally created route, and made a new one, with the
same route name - 'hawkular-metrics' - thinking that any openshift deployed
services would look up the route name. But it seems this is not the case.
It seems it is the route url that is being used.

Is it possible to change the url for hawkular-metrics?
