# Usage Metrics Gathering
|
|
|
|
This document list exactly what is gathered and how.
|
|
|
|
Any change to analytics should most probably include a change to this document.
|
|
|
|
## Dimensions and Metrics
|
|
|
|
Google Analytics Custom Dimensions are used to track system values and flag values. These
|
|
dimensions are aggregated automatically on the backend.
|
|
|
|
One dimension per flag, and although technically there can be an overlap between 2 commands, for
|
|
simplicity it should remain unique across all CLI commands. The dimension is the value of the
|
|
`x-user-analytics` field in the `schema.json` files.
|
|
|
|
### Adding dimension or metic.
|
|
1. Create the dimension or metric in [Google Analytics](https://analytics.google.com/) first. These are not tracked if they aren't
|
|
defined in Google Analytics.
|
|
1. Use the ID of the dimension as the `x-user-analytics` value in the `schema.json` file.
|
|
1. New dimension and metrics PRs need to be approved by the tooling lead and require a new [Launch](http://go/launch).
|
|
|
|
### Deleting a dimension or metic.
|
|
1. Archive the dimension and metric in [Google Analytics](https://analytics.google.com/).
|
|
|
|
|
|
**DO NOT ADD `x-user-analytics` FOR VALUES THAT ARE USER IDENTIFIABLE (PII), FOR EXAMPLE A
|
|
PROJECT NAME TO BUILD OR A MODULE NAME.**
|
|
|
|

## Debugging
|
|
|
|
Using `NG_DEBUG=1` will enable Google Analytics debug mode, To view the debug events, in Google Analytics go to `Configure > DebugView`.
|
|
|
|
## Disabling Usage Analytics
|
|
|
|
There are 2 ways of disabling usage analytics:
|
|
|
|
1. using `ng analytics disable --global` (or changing the global configuration file yourself). This is the same
|
|
as answering "No" to the prompt.
|
|
1. There is an `NG_CLI_ANALYTICS` environment variable that overrides the global configuration.
|
|
That flag is a string that represents the User ID. If the string `"false"` is used it will
|
|
disable analytics for this run.
