This dashboard provides a comprehensive view of Docker container resource usage based on metrics exported by simple-docker-exporter and collected with Prometheus.

What this dashboard shows

For each Docker container, the dashboard visualizes:

CPU

• CPU usage over time (per container)
• CPU usage heatmap for quick comparison
• Average CPU usage over the selected time range

Memory

• Memory usage in bytes
• Memory usage heatmap
• Memory usage ratio and limits (where available)

Network

• Network received bytes
• Network transmitted bytes
• Heatmaps for network I/O activity

Disk / Block I/O

• Block I/O read bytes
• Block I/O written bytes
• Heatmaps for disk activity

Summary table

A combined table showing average values over the selected time range:

• CPU usage (%)
• Memory usage (%)
• Memory usage (bytes)
• Network I/O
• Disk I/O

Dashboard variables

The dashboard includes the following variables:

• job – Prometheus job label
• instance – Prometheus instance label
• container – Docker container name (supports multi-select and All)

These variables allow flexible filtering across hosts and containers.
