Description Matt Wringe 2017-05-02 19:00:47 UTC

Description of problem:
Currently if there is a problem gathering metrics, such as the issue with the ad blockers, we don't get a very useful error message.

Its just something like:

"Metrics are not available.

An error occurred getting metrics for container hawkular-metrics from https://hawkular-metrics.example.com/hawkular/metrics."

When users open bugs about this problem with metrics, we then need to explain to them how to get to their browser's console and to check what the real issue is.

If we could get a more detailed error message when metrics cannot be gathered, it would help to more quickly determine what the problem is.

Not sure what you are suggesting, if knew more information about why it was failing then we could show a better error message.  I believe in a lot of these cases we just get a status code 0 which is the terrible catch all.

We get HTTP status code 0, which can mean a lot of things. It might mean you have no internet connectivity, or it might mean the certificate is not valid. I don't think there's a way for us to know.

Here is the problem we're facing:

http://stackoverflow.com/questions/3825581/does-an-http-status-code-of-0-have-any-meaning/26451773#26451773

Unfortunately, there's no additional information we can give when we see status code 0.
