Gearman

Supported OS Linux Mac OS

Integration version3.1.0

Overview

Collect Gearman metrics to:

  • Visualize Gearman performance.
  • Know how many tasks are queued or running.
  • Correlate Gearman performance with the rest of your applications.

Setup

Installation

The Gearman check is included in the Datadog Agent package, so you don’t need to install anything else on your Gearman job servers.

Configuration

    Host

    To configure this check for an Agent running on a host:

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

      init_config:

instances:
  - server: localhost
    port: 4730

    2. Restart the Agent

    Containerized

    For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.

    ParameterValue
    <INTEGRATION_NAME>gearmand
    <INIT_CONFIG>blank or {}
    <INSTANCE_CONFIG>{"server":"%%host%%", "port":"4730"}

    Log collection

    1. Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml file:

      logs_enabled: true

    2. Add this configuration block to your gearmand.d/conf.yaml file to start collecting your Gearman logs:

      logs:
  - type: file
    path: /var/log/gearmand.log
    source: gearman

      Change the path parameter value based on your environment. See the sample gearmand.d/conf.yaml for all available configuration options.

    3. Restart the Agent.

    See Kubernetes Log Collection for information on configuring the Agent for log collection in Kubernetes environments.

    Validation

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