The first part of the Cache page is the Timeline graph, which plots the cache hits ratio – the percentage of total requests that are served from cache – over time. The time axis units depend on the current time filter setting. For example, with the time set to 1 week, the time axis shows units of days:
Near the top of the graph on the right side is a pulldown allowing you to filter the results by content type.
If you hover the mouse pointer over a point on the plot, the number of cache hits and the percentage at that point is displayed in a box alongside the mouse pointer, with a granularity that depends on the time filter settings.
You can also drag either the left or right side of the zoom control just beneath the timeline to focus on a narrower range of times.
Below and to the left is a donut chart displaying cache Hits vs. Misses. This shows the relative numbers of cache hits, cache misses, and attempts to revalidate cached content. You can hover the mouse pointer over a segment of the chart to display numeric data.
To the right is a Content Types donut chart displaying the distribution of cache hits by content type. You can hover the mouse pointer over a segment of the chart to display numeric data.
