That doesn't seem all that different from > GIT_TRACE. The patch also includes the following part +telemetry.plugin +---------------- + +If the config setting "telemetry.plugin" contains the pathname to a shared +library, the library will be dynamically loaded during start up and events +will be sent to it using the plugin API. + +This plugin model allows an organization to define a custom or private +telemetry solution while using a stock version of Git. + +For example, on Windows, it allows telemetry events to go directly to the +kernel via the plugin using the high performance Event Tracing for Windows +(ETW) facility. + +The contrib/telemetry-plugin-examples directory contains two example +plugins: + * A trivial log to stderr + * A trivial ETW writer which is not a file but, if enabled, some windows internal thingie where the data is gone/duplicated/sent out/whatever. I for my part would much rather prefer that to be a compile time option so that I don't need to check on every git update on windows if this is now enabled or not.
