From Peter Zaitsev:
We seems to have CloudWatch dashboard which was put together as a quick hack. It would be much better for us to have data from CloudWatch going to the Prometheus
The key in this case is it allows us to consistently build the graphs - for example we can show the amount of memory the CloudWatch reports on the node (if it provides it) on the MySQL summary graph etc. It would also allow for us to set up Alerts based on the Prometheus data.
If we just have CloudWatch as separate dashboard it is not right solution long term
