Tell stories with your data.
Chronology comes with everything you need to turn metrics into insights.
The Chronology Project tackles three data-oriented tasks with three tools: Kronos (data collection), Metis (data analysis), and Jia (data visualization). These tools are loosely coupled and can stand alone, but they can also speak with one-another: Metis can query data in Kronos, and Jia can visualize the answers provided by Metis.
Kronos is a time series storage engine that allows you to store and retrieve timestamped JSON blobs from various backends (e.g., Cassandra, Elasticsearch).
Metis is an HTTP compute service. It's currently implemented as a thin HTTP endpoint wrapped around the Spark data processing engine.
Jia is a visualization, dashboarding, and data exploration tool. It can speak with Kronos and Metis. It answers questions for humans, rather than just developers.
