Send Metrics
The metrics collection and analysis plan for Send, a forthcoming Test Pilot experiment.
Analysis
Data collected by Send will be used to answer the following high-level questions:
- Do users send files?
- How often? How many?
- What is the retention?
- What is the distribution of senders?
- How do recipients interact with promotional UI elements?
- Are file recipients converted to file senders?
- Are non-Firefox users converted to Firefox users?
- Where does it go wrong?
- How often are there errors in uploading or downloading files?
- What types of errors to users commonly see?
- At what point do errors affect retention?
Collection
Data will be collected with Google Analytics and follow Test Pilot standards for reporting.
Custom Metrics
cm1
- the size of the file, in bytes.cm2
- the amount of time it took to complete the file transfer, in milliseconds. Only include if the file completed transferring (ref:cd2
).cm3
- the rate of the file transfer, in bytes per second. This is computed by dividingcm1
bycm2
, not by monitoring transfer speeds. Only include if the file completed transferring (ref:cd2
).cm4
- the amount of time until the file will expire, in milliseconds.cm5
- the number of files the user has ever uploaded.cm6
- the number of unexpired files the user has uploaded.cm7
- the number of files the user has ever downloaded.cm8
- the number of downloads permitted by the uploader.

Events
NB: due to how files are being tracked, there are no events indicating file expiry. This carries some risk: most notably, we can only derive expiration rates by looking at download rates, which is prone to skew if there are problems in data collection.
