It looks like the scrape job is failing, but it's hard to say why.

The relevant section of prometheus.yml is:

global:
    scrape_interval: 60s
scrape_configs:
    - job_name: 'joey-server'
      scrape_interval: 5s
      static_configs:
        - targets: ['127.0.0.1:9100']
The relevant section of `prometheus.yml` is: ```yml global: scrape_interval: 60s scrape_configs: - job_name: 'joey-server' scrape_interval: 5s static_configs: - targets: ['127.0.0.1:9100'] ```

$ wget localhost:9100/metrics
wget: can't connect to remote host (127.0.0.1): Connection refused
$ wget 192.168.1.23:9100/metrics
Connecting to 192.168.1.23:9100 (192.168.1.23:9100)

And cating the newly-created metrics file, we can see the proper metrics.

```sh $ wget localhost:9100/metrics wget: can't connect to remote host (127.0.0.1): Connection refused $ wget 192.168.1.23:9100/metrics Connecting to 192.168.1.23:9100 (192.168.1.23:9100) ``` And `cat`ing the newly-created metrics file, we can see the proper metrics.
