--- title: Quarkus description: Monitor your application built with Quarkus. breadcrumbs: Docs > Integrations > Quarkus --- # Quarkus Supported OS Integration version2.3.0 ## Overview{% #overview %} This check monitors [Quarkus](https://quarkus.io/) through the Datadog Agent. **Minimum Agent version:** 7.62.0 ## Setup{% #setup %} Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the [Autodiscovery Integration Templates](https://docs.datadoghq.com/agent/kubernetes/integrations/) for guidance on applying these instructions. ### Installation{% #installation %} The Quarkus check is included in the [Datadog Agent](https://app.datadoghq.com/account/settings/agent/latest) package starting with Agent 7.62. No additional installation is needed on your server. ### Configuration{% #configuration %} Follow [these steps](https://quarkus.io/guides/telemetry-micrometer-tutorial) to set up metric generation in Quarkus. Then configure the Agent: 1. Edit the `quarkus.d/conf.yaml` file, in the `conf.d/` folder at the root of your Agent's configuration directory to start collecting your Quarkus performance data. See the [sample quarkus.d/conf.yaml](https://github.com/DataDog/integrations-core/blob/master/quarkus/datadog_checks/quarkus/data/conf.yaml.example) for all available configuration options. 1. [Restart the Agent](https://docs.datadoghq.com/agent/guide/agent-commands/#start-stop-and-restart-the-agent). #### Collecting Logs{% #collecting-logs %} Follow [these steps](https://quarkus.io/guides/logging) to configure Quarkus to emit logs. Collecting logs is disabled by default in the Datadog Agent. Enable it in your `datadog.yaml` file: ```yaml logs_enabled: true ``` Edit the `logs` section of your `quarkus.d/conf.yaml` file to start collecting your RabbitMQ logs: ```yaml logs: - type: file path: /var/log/application.log source: quarkus service: quarkus-app ``` ### Validation{% #validation %} [Run the Agent's status subcommand](https://docs.datadoghq.com/agent/guide/agent-commands/#agent-status-and-information) and look for `quarkus` under the Checks section. ## Data Collected{% #data-collected %} ### Metrics{%
