Overview

This check monitors Puma through the Datadog Agent with the Puma metrics endpoint provided by the control and status server.

Setup

The Puma 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 Puma 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-puma==<INTEGRATION_VERSION>

  2. Configure your integration similar to core integrations.

Configuration

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

  2. Restart the Agent.

Validation

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