We are facing this issue in self monitoring. We got the below incident. Please help me over this and also provide root cause for this incident.
If you need urgent help I suggest you open a support case and provide the information our support team requires (which would be at least a support archive besides the screenshot).
The warning you get is because data cannot be written to the performance warehouse fast enough. It takes 67 seconds to write 1 minute worth of data. Root cause could be you are not using a real database (Oracle, Postgre, SQL-Server or DB2), your database is sized too small or you have too many measures subscribed that are persisted.
