Overview

Kapacitor Enterprise installations are very similar to open source Kapacitor but require a an Enterprise license key and include extra configuration options.

The basic installation steps are:

1. Download Kapacitor Enterprise
2. Configure Kapacitor Enterprise
3. Start Kapacitor Enterprise

Kapacitor Enterprise has only a single type of member, meaning every member of a cluster is the same and performs the same functions.

Step 1: Download Kapacitor Enterprise

Sign in to the InfluxPortal to view your Enterprise license key and access the download links.

Click on the download icon in your dashboard and agree to the Software Software License Subscription Agreement to view package download links.

Download the package appropriate for your operating system and un-package the contents. Add the binaries included in <package_dir>/usr/bin/ to your system’s $PATH.

Step 2: Configure Kapacitor Enterprise

Configuring Kapacitor Enterprise is similar to the open source Kapacitor, with a few additional sections in the kapacitor.conf. View the Kapacitor Enterprise Configuration documentation for more details.

To print out an example Kapacitor Enterprise configuration, run:

kapacitord config

Use the example configuration to create your own custom kapacitor.conf. Update the essential information to suit your specific installation.

Provide your enterprise license key

In your kapacitor.conf provide either your full enterprise license key in the license-key configuration or the path to a file containing your license key using the license-path configuration. These configurations are mutually exclusive and should not be used together.

[enterprise]
  # ...
  license-key = "xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx"

# OR

[enterprise]
  # ...
  license-path = "/path/to/kapacitor-enterpise-license.txt"

If you don’t want to store your license key in your kapacitor.conf, you can also provide your license key using the KAPACITOR_LICENSE_KEY or KAPACITOR_LICENSE_PATH environment variables.

Other enterprise-specific configuration options

Kapacitor enterprise includes additional configuration options that are covered in the Kapacitor Enterprise Configuration documentation. There are also options related to clustering and alerts that are covered in detail in the Kapacitor clustering documentation.

Save your kapacitor.conf

Save your customized kapacitor.conf in the filesystem of the server on which it will be used. The location of your kapacitor.conf is important when starting Kapacitor.

Step 3: Start the Kapacitor daemon

With Kapacitor Enterprise configured, start the Kapacitor daemon using the kapacitord binary.

kapacitord

Specify the location of your kapacitor.conf

You have a few options for telling Kapacitor where your kapacitor.conf is located:

1. When staring Kapacitor, pass the path to the configuration file with kapacitord’s -config option.

   kapacitord -config /path/to/kapacitor.conf

2. Define the path to the kapacitor.conf using the KAPACITOR_CONFIG_PATH environment variable.

3. Place your kapacitor.conf at one of the expected locations:

   • ~/.kapacitor/
   • /etc/kapacitor/
