When generating your Synapse configuration file, you are asked whether you -would like to report anonymised statistics to Matrix.org. These statistics -provide the foundation a glimpse into the number of Synapse homeservers -participating in the network, as well as statistics such as the number of -rooms being created and messages being sent. This feature is sometimes -affectionately called "phone-home" stats. Reporting -is optional -and the reporting endpoint -can be configured, -in case you would like to instead report statistics from a set of homeservers -to your own infrastructure.

This documentation aims to define the statistics available and the -homeserver configuration options that exist to tweak it.

The following statistics are sent to the configured reporting endpoint:

Native matrix users and guests are always counted. If the -track_puppeted_user_ips -option is set to true, "puppeted" users (users that an Application Service have performed -an action on behalf of) -will also be counted. Note that an Application Service can "puppet" any user in their -user namespace, -not only users that the Application Service has created. If this happens, the Application Service -will additionally be counted as a user (irrespective of track_puppeted_user_ips).

If statistics reporting is enabled, the endpoint that Synapse sends metrics to is configured by the -report_stats_endpoint config -option. By default, statistics are sent to Matrix.org.
