We here on the Mozilla Services team are happy to announce our first beta release (v0.2b1) of Heka, a tool for high performance data gathering, analysis, monitoring, and reporting. Heka’s main component is hekad, a lightweight daemon program that can run on nearly any host machine which does the following:
* Gathers data through reading and parsing log files, monitoring server health, and/or accepting client network connections using any of a wide variety of protocols (syslog, statsd, http, heka, etc.).
* Converts the acquired data into a standardized internal representation with a consistent metadata envelope to support effective handling and processing by the rest of the Heka system.
* Evaluates message contents and metadata against a set of routing rules and determines all of the processing filters and external endpoints to which a message should be delivered.
* Processes message contents in-flight, to perform aggregation, sliding-window event processing and monitoring, extraction of structured data from unstructured data (e.g. parsing log file output text to generate numeric stats data and/or more processing-friendly data structures), and generation of new messages as reporting output.
* Delivers any received or internally generated message data to an external location. Data might be written to a database, a time series db, a file system, or a network service, including an upstream hekad instance for further processing and/or aggregation.
