Heka

Heka is an open source stream processing software system developed by Mozilla. Heka is a “Swiss Army Knife” type tool for data processing, useful for a wide variety of different tasks, such as:

  • Loading and parsing log files from a file system.
  • Accepting statsd type metrics data for aggregation and forwarding to upstream time series data stores such as graphite or InfluxDB.
  • Launching external processes to gather operational data from the local system.
  • Performing real time analysis, graphing, and anomaly detection on any data flowing through the Heka pipeline.
  • Shipping data from one location to another via the use of an external transport (such as AMQP) or directly (via TCP).
  • Delivering processed data to one or more persistent data stores.
