Storage and traffic metrics
📦
Bytes in, bytes out.
The storage and traffic group of the metrics tab shows how much disk space an environment uses, how many bytes it sends and receives, and how many static files it serves.
Web storage
The disk space the environment uses. A sample holds the size at that moment. A bar shows four values from its samples:
- max: the largest size of the hour or day
- last: the size at the end of the hour or day
- avg: the average size
- min: the smallest size
A last well below the max of the same day means the size dropped during that day, for example after a cleanup. The lines mark the sizes of the storage plans. See why storage grows.
Traffic
Bytes sent to and received from visitors. A sample holds the bytes since the sample before, a bar is the sum of its samples. In the box, the sum covers the whole time frame and max is the busiest hour or day. See why traffic grows.
Static requests
Requests answered from a file without PHP, such as images, CSS, JavaScript and fonts. They are counted like traffic: one bar is the sum of its samples. See page weight.
Labels and lines
The values each metric shows in one bar, for the time frame, and on the summary page, and the lines drawn across the chart:
| Metric | One bar | Time frame | Summary | Lines |
