Opting out of telemetry

We collect a few metrics to help us understand basic usage.

Which command is run, never the arguments or flags
OS & arch
the hof version

link to code

To opt out of telemetry, set HOF_TELEMETRY_DISABLED=1

Long term, we will move to the Go strategy, which uses a probability based method for reducing metrics even further, i.e to collect enough for statistical significance and much more focused to the questions at hand.
