Overview

OpenTelemetry MySQL metrics in a MySQL dashboard

The MySQL receiver allows for collection of MySQL metrics and access to the MySQL Overview dashboard. Configure the receiver according to the specifications of the latest version of the mysqlreceiver.

For more information, see the OpenTelemetry project documentation for the MySQL receiver.

Setup

To collect MySQL metrics with OpenTelemetry for use with Datadog:

Configure the MySQL receiver in your OpenTelemetry Collector configuration.
Ensure the OpenTelemetry Collector is configured to export to Datadog.

See the MySQL receiver documentation for detailed configuration options and requirements.
