Let's assume that you're invited to my organisation to look into my platform, which has thousands of databases if not less, and you are requested to check various aspects of these databases to tell me where I am going wrong w.r.t administration, health checks, backups, etc.
What would be the points that you'd cover during such an excercise?
E.g., how the backups are being taken? What parameters to monitor day by day? Script(s) to identify bad queries? Etc ..
Some suggestions in this regard would be really helpful.
