We run a handful of Amazon RDS and are usually able to view basic monitoring metrics (such as free space, freeable memory, CPU utilisation etc.) in the appropriate tab via the AWS Console.
At present, none of our RDS instance monitoring tabs shows any data. I've tried extending the window of time reported, but to no avail.
Has anyone else experienced this issue and, if so, what was the cause/how did you overcome it? Screenshot here: Missing Cloudwatch Data
