HMAC

HMAC AKA HSDP Metrics Alerts Collector is a tiny microservice which acts as a webhook receiver for the alerts generated by the HSDP Metrics alerts service.

Description

This microservice can run standalone but can also be deployed as a sidecar as part of a Grafana frontend. The service collects and stores alert payloads in a PostgreSQL database. The application is optimized for deployment to Cloud foundry but can also run on other container orchestration platforms. It uses gautocloud for service configuration.
