Installation

This page provides directions for installing, starting, and configuring Kapacitor.

Requirements

Installation of the InfluxDB package may require root or administrator privileges in order to complete successfully.

Networking

Kapacitor listens on TCP port 9092 for all API and write calls.

Kapacitor may also bind to randomized UDP ports for handling of InfluxDB data via subscriptions.

Installation

Kapacitor has two binaries:

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

You can download the binaries directly from the downloads page.

Start the Kapacitor Service

For packaged installations, please see the respective sections below for your operating system. For non-packaged installations (tarballs or from source), you will need to start the Kapacitor application manually by running:

./kapacitord -config <PATH TO CONFIGURATION>

OS X (via Homebrew)

To have launchd start Kapacitor at login:

ln -sfv /usr/local/opt/kapacitor/*.plist ~/Library/LaunchAgents

Then to load Kapacitor now:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.kapacitor.plist

Or, if you don’t want/need lanchctl, you can just run:

kapacitord -config /usr/local/etc/kapacitor.conf

Linux - SysV or Upstart Systems

To start the Kapacitor service, run:

sudo service kapacitor start

Linux - systemd Systems

To start the Kapacitor service, run:

sudo systemctl start kapacitor

Configuration

An example configuration file can be found here

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

kapacitord config

To generate a new configuration file, run:

kapacitord config > kapacitor.generated.conf
