MetricBeat on Openshift

[jaikunwar]

I am trying to run metricbeat on openshift using docker file:
#Docker file:
FROM docker-secure-com/metricbeat/metricbeat:latest
COPY metricbeat.yml /etc/metricbeat/config/metricbeat.yml
COPY metricbeat.yml /etc/metricbeat/metricbeat.yml
My pod is running. But I have 2 question:
1> how to test if metric beat is running/test?
2> I run command metric beat by login to pod which gives error as
sh-4.2$ metricbeat

You can find details how to run metricbeat in the docker runtime here: https://www.elastic.co/guide/en/beats/metricbeat/current/running-on-docker.html

Regarding testing... hm, I believe you can watch the metricbeat process output for ERROR and produced log lines (to see if it's not dead), but it requires a bit of scripting.
