Interestingly enough, I added a MySQL RDS node. The performance_schema is turned on, on the instance. However, it does not show up in the QAN. It does show up in the general dashboard showing CPU usage etc. What else could I be missing?
Thanks in advance!
I would like to suggest you to read Planet MySQL this. Here is the all information you want. Something is missing, which I saw here. Please check. Let me know if you have questions
Make sure that the user that PMM is using has permissions to SELECT from performance_schema. Check out the documentation as well:
