Sending metrics to a pushgateway (HTTPS) with authentication

[Pradeep]

Hello All,

I am trying to send the runtime of a scala job as a metric to pushgateway running on another server. The pushgateway URL is like https://pushgateway.de/pushgateway which redirects to :9091/metrics. I am using the below code where I am passing the URL, username and password from the docker run command.

----------------------------------------------------------------------------------------

val pg = new PushGateway(hostname)

val username = sys.env("PROMETHEUS_USERNAME")

val password = sys.env("PROMETHEUS_PASSWORD")

pg.setConnectionFactory(pg.setConnectionFactory(new BasicAuthHttpConnectionFactory(username, password)) pg.pushAdd(registry, jobName)

pg.pushAdd(registry, jobName)

-----------------------------------------------------------------------------------------

When I run this code I get the below error

Exception in thread "main" java.net.UnknownHostException: https

I curled the URL and I am able to do it. Could you please let me know how can I resolve this issue?
