Build Status

A Dart library to upload metrics data to


To use this library, instantiate an instance of the Librato class and call its postStats method to post a set of statistics.

You need to provide a Librato username and access token, either explicitly in the constructor, or implicitly via environment variables (LIBRATO_USER and LIBRATO_TOKEN).

Librato librato = new Librato.fromEnvVars();
List<LibratoStat> stats = [
  new LibratoStat('benchmarkTime', 130);
  new LibratoStat('compiledAppSize', 230000);
