  1. I’ve downloaded a report for 2 months, IE a separate report for each. both are just over 60MB in size and both show exactly 50000 entries – that makes me think there’s some sort of limit on reporting / export as I can’t see how both months would have exactly the same number of events.

  2. The audit logs download feature is a joke. There’s a 50,000 entries limit, not shown anywhere, and there’s no way to tell in advance if the selected timerange will export more lines than the limit.
    The download speed is slow as hell, hovering between 0 and a max of 150k/s, with frequent pauses. Remember eMule? Except the final file is not necessarily porn in disguise.
    File format: CSV, yes. but the last field is a JSON, and it’s where you will find _all_ the necessary information. Including the values from all the other CSV fields.
    Oh, and last but not least, some lines are too long, and they get truncated. Repeat after me: incomplete audit logs. Brilliant!
