Is there a way to get the write lag? I can see it printed to the log, but I'm not seeing it in stats.json or metrics.json

+1 I would be very interested in that as well

The write lag is available in the

/stats.json

endpoint, under

pending_write_batches

That's interesting, I was getting a value of 0 for that field even though the log was printing out the lag (and my clients were getting the 503 - Not Ready or Lagging). I'll pay more attention to that field next time it happens.
