agentmon: Secret Dyno Metrics Agent Mon

Overview

The agentmon application reads language metrics from a Prometheus or a StatsD source, then translates and aggregates the metrics data to a format expected by the language metrics sink. It posts the data to the language metrics sink located at https://app.metrics.heroku.com. A typical use case would be to add agentmon to a buildpack and set an environment variable HEROKU_METRICS_URL to https://app.metrics.heroku.com/<dyno id>. agentmon will read the language metrics sink URL from the environment variable when it starts and use it to post language metrics.

For more about what agentmon actually does, and its modes of operation, see design.
