Hi ElegantKangaroo44 ,
This is basically the number of average number of experiments running, and the number of projects, and number of users. I think this is about it. nothing like google-analytics stuff. It is mainly aimed at giving some idea on how large is the usage. Sounds reasonable?
From the https://github.com/allegroai/trains-server/releases/tag/0.13.0 :
Reports average load metrics per day (CPU/memory) Reports average workload per day (amount and average duration of queues, agents and experiments)
