What is a heatmap in Docker's context?

In Docker's context, a heatmap serves as a graphical representation that visualizes the usage patterns of containers or services. This tool helps developers and system administrators easily identify performance bottlenecks, resource hotspots, and overall utilization trends in a system. By providing a visual depiction of how containers are consuming resources over time, heatmaps allow for quick analysis and informed decision-making regarding scaling, resource allocation, and optimization strategies.

This concept is particularly valuable in environments where multiple containers are deployed, as it enables clear comparisons between different services or containers and highlights which ones may require attention or further investigation based on their usage metrics. Understanding resource consumption patterns is crucial for maintaining efficient operations and ensuring reliable performance in a containerized environment.
