Overview

This check monitors Riak replication riak-repl.

Setup

The Riak-Repl check is not included in the Datadog Agent package, so you need to install it.

Installation

For Agent v7.21+ / v6.21+, follow the instructions below to install the Riak-Repl check on your host. See Use Community Integrations to install with the Docker Agent or earlier versions of the Agent.

  1. Run the following command to install the Agent integration:

    datadog-agent integration install -t datadog-riak_repl==<INTEGRATION_VERSION>

  2. Configure your integration similar to core integrations.

Configuration

  1. Edit the riak_repl.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your riak_repl performance data. See the sample riak_repl.d/conf.yaml for all available configuration options.

  2. Restart the Agent

Validation

Run the Agent’s status subcommand and look for riak_repl under the Checks section.
