Nuria,I've restructured the Wiki page in a way which is easier to understand from my POV.Please check if it's still correct. The part I still was a bit confused about is https://wikitech.wikimedia.org/wiki/EventLogging/Testing/BetaLabs#Raw_stream_of_events_.28including_unvalidated_events.29If events do not appear they might not be valid, check/var/log/upstart/
for either the server-side or the client-side processor logs. Validation errors will appear on those logs and they are very descriptive.I don't think this is correct but I don't know which files you are actually talking about, how to verify event validation.RE:stat1002. I've never used it before. I've only used stat1003 to verify event logging using zsub. Maybe you or someone else could show me sometimes how to actually verify event logging in production?Thanks,Bernd
