README

Kapacitor Circle CI

Open source framework for processing, monitoring, and alerting on time series data

Installation

Kapacitor has two binaries:

  • kapacitor – a CLI program for calling the Kapacitor API.
  • kapacitord – the Kapacitor server daemon.

You can either download the binaries directly from the downloads page or go get them:

go get github.com/influxdata/kapacitor/cmd/kapacitor
go get github.com/influxdata/kapacitor/cmd/kapacitord

Configuration

An example configuration file can be found here

Kapacitor can also provide an example config for you using this command:

kapacitord config

Getting Started

This README gives you a high level overview of what Kapacitor is and what its like to use it. As well as some details of how it works. To get started using Kapacitor see this guide.

Basic Example

Kapacitor use a DSL named TICKscript to define tasks.

A simple TICKscript that alerts on high cpu usage looks like this:

stream
    |from()
        .measurement('cpu_usage_idle')
        .groupBy('host')
    |window()
        .period(1m)
        .every(1m)
    |mean('value')
    |eval(lambda: 100.0 - "mean")
        .as('used')
    |alert()
        .message('{{ .Level}}: {{ .Name }}/{{ index .Tags "host" }} has high cpu usage: {{ index .Fields "used" }}')
        .warn(lambda: "used" > 70.0)
        .crit(lambda: "used" > 85.0)

        // Send alert to hander of choice.

        // Slack
        .slack()
        .channel('#alerts')

        // VictorOps
        .victorOps()
        .routingKey('team_rocket')

        // PagerDuty
        .pagerDuty()

Place the above script into a file cpu_alert.tick then run these commands to start the task:

# Define the task (assumes cpu data is in db 'telegraf')
kapacitor define \
    -name cpu_alert \
    -type stream \
    -dbrp telegraf.default \
    -tick ./cpu_alert.tick
# Start the task
kapacitor enable cpu_alert

Documentation

Overview

A data pipeline processing engine.

See the README for more complete examples and guides.

Code Organization:

The pipeline package provides an API for how nodes can be connected to form a pipeline. The individual implementations of each node exist in this kapacitor package. The reason for the separation is to keep the exported API from the pipeline package clean as it is consumed via the TICKscripts (a DSL for Kapacitor).

Other Concepts:

Stream vs Batch -- Use of the word 'stream' indicates data arrives a single data point at a time. Use of the word 'batch' indicates data arrives in sets or batches or data points.

Task -- A task represents a concrete workload to perform. It consists of a pipeline and an identifying name. Basic CRUD operations can be performed on tasks.

Task Master -- Responsible for executing a task in a specific environment.

Replay -- Replays static datasets against tasks.

type UDFNode added in v0.10.0 

type UDFNode struct {
	// contains filtered or unexported fields

User defined function

func (*UDFNode) Wait added in v0.11.0 

func (n *UDFNode) Wait() error

type UDFProcess added in v0.10.0

	PointIn chan<- models.Point

	BatchIn chan<- models.Batch

	PointOut <-chan models.Point

	BatchOut <-chan models.Batch
	// contains filtered or unexported fields
}

Wraps an external process and sends and receives data over STDIN and STDOUT. Lines received over STDERR are logged via normal Kapacitor logging.

Once a UDFProcess is created and started the owner can send points or batches to the subprocess by writing them to the PointIn or BatchIn channels respectively, and according to the type of process created.

The UDFProcess may be Aborted at anytime for various reasons. It is the owner's responsibility via the abortCallback to stop writing to the *In channels since no more selects on the channels will be performed.

Calling Stop on the process should only be done once the owner has stopped writing to the *In channel, at which point the remaining data will be processed and the subprocess will be allowed to exit cleanly.

Callling Info returns information about available options the process has.

Calling Init is required to process data. The behavior is undefined if you send points/batches to the process without calling Init.

func NewUDFProcess added in v0.10.0

type UDFProcessInfo struct {
	Commander command.Commander
