Am I using this correctly? #19

Hi,

I'm using the precompiled binary on Linux, running on a local machine which is pointing at a remote server.

My cmd line looks like this (machine names obscured)

./kafka-health-check -broker-host kafka-host -broker-id 1 -zookeeper kafka-host:2181

When I run this, I get the following output...

time="2018-01-09T11:50:13Z" level=info msg="using topic broker-1-health-check for broker 1 health check" time="2018-01-09T11:50:13Z" level=info msg="using topic broker-1-health-check for broker 1 replication check"

I don't get any other output, and I'm not sure if that's correct or not. I'm not seeing any topics created in Kafka. If I query the health status on port 8000 I get

{"status": "nook"}

As far as I can tell, Kafka is working correctly, does anyone have any idea what's going on and is there any way I can diagnose it?

I ran into this same behavior and you have to look at your Kafka logs to see what errors you see there. In my case, I had an SSL and PLAINTEXT listener defined in listeners property, but only one listener defined in my advertised.listeners property. Once I fixed this in all three Kafka brokers I started getting more output.

Admittedly, the program could do a better job of reporting the failure it receives in logs.
