[Hawkular-dev] gohawk - need Go code to write to H-Metrics

[Michael Burman]

Hi,

I'm not sure why I write documentation ;)

" Writing datapoints" section says:

err  :=  c.Write([]MetricHeader{header})

So just use c.Write(yourMetricHeaderArray). If you initialized with 
correct settings (from the "Initialization " part) with 
NewHawkularClient(), you don't need to do anything else. SSL settings 
are provided by giving &tls.Config to it (standard way in Golang to set 
TLS settings).

Unit test with TLS:

https://github.com/hawkular/hawkular-client-go/blob/master/metrics/client_test.go#L267

And almost every unit test uses Write in client_test.go. Remember 
there's internal pooling in the Golang client, so if you need 
concurrency, don't be afraid to spawn goroutines and let the client take 
care of the concurrency limits to the server (adjustable with Parameters 
in initialization).

I could even demo what I got if some folks are interested in learning how GoHawk is configured (YAML!!!), seeing it react to changes to an Open Shift node environment on the fly, collecting Prometheus data, and mock-storing the metrics to h-Metrics.

This isn't code that QUERIES the H-Metrics for existing metric data - it is code that WRITES metrics to Hawkular Metrics. I already have a array of MetricHeader objects ([]metrics.MetricHeader) - I just need code that builds up the HTTP request and sends it (including any encryption/credential parameters/settings required?).
