This check monitors Helm deployments through the Datadog Agent.
Helm supports multiple storage backends. In v3, Helm defaults to Kubernetes secrets and in v2, Helm defaults to ConfigMaps. This check supports both options.

The Helm check is included in the Datadog Agent package.
No additional installation is needed on your server.
Configuration
This is a cluster check. You can enable this check by adding datadog.helmCheck.enabled to your Helm chart.
Note: If no configuration is required, an empty conf.d can be passed.
For more information, see the Cluster Check documentation.
