1. Do the same people where you work operate the cluster and write the code to develop the application?
Mostly. Ops vs dev, although there's some overlap 2. Do you have a metrics stack that allows you to see graphs of various metrics with all the nodes displayed together? Yes, Prometheus+Grafana (currently custom script reporting to Prometheus, but that needs revisiting) 3. Do you have a log stack that allows you to see the logs for all the nodes together? Yep, graylog. 4. Do you regularly repair your clusters - such as by using Reaper? Yes, with reaper. Every day or two, more or less. It would be almost-constant if Reaper could work off queues with blacklisted time windows instead of a schedule 5. Do you use artificial intelligence to help manage your clusters? No. On Thu, Mar 28, 2019 at 8:46 AM Tom van der Woerdt <tom.vanderwoe...@booking.com.invalid> wrote: > 1.
