`/api/v1/metrics`

[pcj]

If the artifactory system.yaml has metrics enabled, this provides additional metrics for prometheus. One could scrape the metrics off that directly, but it is still behind basic auth, so I am thinking this exporter might be able to reverse proxy that. WDYT? Thinking about creating a PR

These are the metrics:

@pcj I like the idea, just making it optional and default to false should be good. I would be glad to look at the PR 👍

[pcj]

So far we are OK with the metrics we have, not planning a PR just yet. I suppose if we have some instability we'd like to add this.

I ended up just creating an nginx proxy for the basic auth. Here's what that looks like:

events {
  worker_connections  4096
}
http {
    server { 
        listen 80;
        location /metrics {
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://your-artifactory-endpoint:80/artifactory/api/v1/metrics;
            proxy_set_header Authorization "Basic {echo -n 'admin:password' | base64}";
        }
    }
}
