TODO

• Support config.yml ( -c, --config )
• --target endpoint query string ( like --target=http://:9100/metrics?role=app&hostname=app-1.internal) to label
• Default http.Client setting
• Service discovery
• Auto update metrics graph definition

Alternatives

• mackerel-plugin-prometheus-query: Prometheus query plugin for Mackerel.
