## Project history and usage

Kapacitor is InfluxData's time-series processing and alerting engine, built to process stream and batch data from InfluxDB with TICKscript.

### Project history

Kapacitor grew out of the InfluxData time-series stack as the action and processing layer paired with InfluxDB. InfluxData describes it as the native data processing engine for InfluxDB 1.x and an integrated component in the InfluxDB 2.0 platform, able to process both stream and batch data.

### Adoption history

Kapacitor became familiar to operators through the TICK stack: Telegraf collected metrics, InfluxDB stored them, Chronograf visualized them, and Kapacitor transformed, analyzed, and acted on them. Its presence in Homebrew, Scoop, winget, and Nix reflects its use as both a server daemon and an operator CLI in monitoring setups.

### How it is used

A typical Kapacitor setup runs kapacitord, defines tasks with TICKscript, subscribes to InfluxDB data, and routes alerts or computed output through handlers. The kapacitor CLI and HTTP API are used to define tasks, manage recordings, inspect task state, and administer the daemon.

### Why package nerds care

Kapacitor is a classic infrastructure package because it ships both a daemon and a CLI, keeps its main configuration under /etc, and ties package installation directly to service management. For package nerds it marks the era when time-series monitoring stacks were installed as composable Unix services before hosted observability platforms dominated many workflows.

### Timeline

- 2016: Kapacitor's v1.0.0-beta1 GitHub milestone closed on July 22 during the 1.0 stabilization period.
- 2020: Kapacitor 1.6 added Flux task support and moved user authentication and authorization into the open source distribution.
- 2025: Kapacitor 1.7.7 release notes deprecated Python 2 user-defined functions ahead of the 1.8 line.

### Related projects

- InfluxDB is the database Kapacitor was built to process data from.
- Telegraf and Chronograf are the other named tools in the TICK stack.
- Flux and TICKscript are the query/task languages most closely associated with Kapacitor's evolution.
