⁠Metrics

• http://host:9571/metrics⁠

⁠Format

helm_chart_info{chart="ark",release="ark",version="1.2.1",latestVersion="1.2.3",appVersion="1.2.3",updated="1553201431",namespace="test"} 1
helm_chart_info{chart="cluster-autoscaler",release="cluster-autoscaler",version="0.7.0",latestVersion=7.3.2,appVersion="",updated="1553201431",namespace="other"} 4
helm_chart_info{chart="dex",release="dex",version="0.1.0",latestVersion="3.4.0",appVersion="1.2.3",updated="1553201431",namespace="test"} 1

The metric value is the helm status code. These status codes indexes do not map up directly to helm. This is so I can make the bad cases negative values.
