What are the environment variables used to ignore containers?

The use of environment variables in Datadog for managing how containers are monitored is essential for tailoring observability to specific needs. The correct answer refers to the environment variables DD_CONTAINER_INCLUDE and DD_CONTAINER_EXCLUDE, which are specifically designed to either include or exclude containers in monitoring.

DD_CONTAINER_INCLUDE allows you to specify which containers you want to monitor, providing flexibility to only observe certain workloads that are critical for performance or resource management. Conversely, DD_CONTAINER_EXCLUDE enables you to specify which containers should be ignored during monitoring, which can be useful for excluding transient, irrelevant, or non-essential containers from your metrics. This capability helps reduce noise in monitoring data and allows for a more effective focus on significant performance metrics.

By utilizing these environment variables, you can customize the observability of your containerized applications according to operational requirements. This is crucial for maintaining efficiency and relevance in monitoring, ensuring that the data collected aligns closely with business objectives and operational efficiency.
