Prana

Netflix have something similar https://github.com/Netflix/Prana and I've got a Sidecar in Micro too https://github.com/micro/micro/tree/master/car. It's a solid model for integrating applications which you don't necessarily have client libraries for or don't speak the same protocol.

There are several different data sources for Atlas: * There is a poller cluster that gathers SNMP and HTTP healthcheck metrics and forwards them to the Atlas backend. * There are on-instance log parsers written in Perl and Python that count events in Apache HTTPd and Tomcat logs and send data to the Atlas backend. * The Servo library [0] is used to instrument Java code with counters, timers and gauges. There is a separate client implementation that handles forwarding metrics to the Atlas backend. The client also polls and reports JMX metrics from the JVM that it runs inside. Spectator [1] is a new library that provides cleaner abstractions of Servo concepts. * The Prana sidecar [2] was extended to provide REST endpoints for Servo and the client, so that metrics can be delivered from non-Java code.
