## What it is
Kapacitor is an open-source framework for processing, monitoring, and alerting on time series data, part of the InfluxData TICK stack. It uses a DSL called TICKscript to define stream and batch processing tasks that can compute metrics and trigger alerts to services like Slack, PagerDuty, and VictorOps.

## Use cases
- alert on high cpu usage from telegraf metrics
- process and downsample time series streams
- send alerts to slack or pagerduty when thresholds are breached
- run anomaly detection on streaming metrics
- batch process historical time series data
- monitor infrastructure metrics in real time

## When to choose
- you use InfluxDB/Telegraf and need stream processing and alerting on time series data
- you want a DSL-based pipeline for metric transformation and threshold alerts
- you need a self-hosted alerting engine with many alert handler integrations

## When to avoid
- you need a general-purpose stream processing platform like Kafka Streams or Flink
- your data is not time series
- you want a modern actively evolving ecosystem - the project is largely in maintenance mode

## Facets
- artifact type: framework
