Limitations

  • A vendor claim: the unit (requests, sessions or users) and the detection method are not published.

For designers

Agent use can be a large share of a developer tool's use, so it is worth measuring as its own segment. Ask how a vendor defines and detects "agent use" before comparing figures.
