Visualizing Systems Behavior: Subsecond Offset Heat Maps

This one is for ops, devops, noops and everyone else that loves some state-of-art real-systems behavior visualizations and investigation:

The subsecond offset heat map puts time on two axes. The x-axis shows the passage of time, with each column representing one second. The y-axis shows the time within a second, spanning from 0.0s to 1.0s (time offsets). The z-axis (color) show the count of samples or events, quantized into x- and y-axis ranges (“buckets”), with the color darkness reflecting the event count (darker == more).
