Calculate rates across joined series + backfill

Use a prepared data generator to calculate rates across joined series and backfill.

Custom anomaly detection using Kapacitor

Detect anomalies in Kapacitor with user-defined functions (UDFs).

Handle Kapacitor alerts during scheduled downtime

Build Kapacitor TICKscripts that gracefully handle scheduled downtime without triggering unnecessary alerts.

Kapacitor as a Continuous Query engine

Use Kapacitor to downsample and process data at scheduled intervals.

Live leaderboard of game scores

Tutorial on using Kapacitor stream processing and Chronograf to build a leaderboard for gamers to be able to see player scores in realtime. Historical data is also available for post-game analysis.
