On the last Golang Barcelona meetup we decided to try new format of conversation and after the talk started open discussion on logging, tracing and metrics. The idea was to encourage people to read a very nice blog post by Peter Bourgon on this subject - "Metrics, Tracing and Logging" and discuss it in a free format.
