This module implements native types and providers to manage some aspects of Kapacitor. The providers are fully idempotent.

The kapacitor module allows to automate the configuration and deployment of Kapacitor templates and tasks.

The module requires the kapacitor-ruby rubygem. It also requires Puppet >= 4.0.0.

If you are using Puppet AIO, you may want to include the gem as part of the base installation. If not, you can install it as follows:

/opt/puppetlabs/puppet/bin/gem install kapacitor-ruby

Furthermore, on your puppet master, you'd need to install the toml rubygem. If you use puppetserver, you can install it as follows:

puppetserver gem install toml

This is needed to generate Kapacitor's configuration file.

The include the main class as follows:

include kapacitor
