Timeline:
May 10, 2023, 09:15 AM (UTC): Danger bells rang loud and clear as monitoring alerts screamed about soaring error rates and sluggish response times.
In the midst of the chaos, an engineer stepped forward, wielding their debugging wand, as a swarm of support tickets and customer complaints flooded in.
Heroes from the development, operations, and database teams assembled to investigate the malevolent force that was hampering our application's performance. They suspected the dragon of database overload lurking beneath the surface.
Alas, the adventurers embarked on misleading paths, diligently optimizing the application server and even scaling up the database infrastructure. Little did they know, the dragon was hiding elsewhere.
