Yeah. I just created this hack/ script to make it easy for most people. At least good enough to get linux users up and running fairly painlessly and quickly.

BTW: I just noticed that those OpenShift docs are incorrect - its pointing to the wrong github links to wget. It says:

===
$ wget https://github.com/openshift/origin-metrics/blob/master/hawkular-agent/hawkular-openshift-agent-configmap.yaml
$ wget https://github.com/openshift/origin-metrics/blob/master/hawkular-agent/hawkular-openshift-agent.yaml
===

But when you wget those, you are getting the actual HTML page for those files. We want to tell the user to get the raw files, whose links are:

https://raw.githubusercontent.com/openshift/origin-metrics/master/hawkular-agent/hawkular-openshift-agent-configmap.yaml
