Prometheus is an open-source monitoring and alerting toolkit originally developed by SoundCloud in 2012. It was designed to monitor systems, track metrics, and trigger alerts based on those metrics. Prometheus uses a powerful query language called PromQL to collect and analyze time-series data from various services and applications. It stores data in a time-series database, making it easy to track trends over time. Prometheus is now a part of the Cloud Native Computing Foundation (CNCF) and is widely used in cloud-native environments for monitoring microservices, containers, and more.
Funny Version
Imagine throwing a party where you need to keep track of everything — from who’s dancing to how loud the music is. Prometheus is like your super-organized friend who monitors it all in real-time, sending you alerts if the punch bowl is low or if a conga line breaks out. Born at SoundCloud in 2012, Prometheus quickly became the ultimate party planner for techies, ensuring everything runs smoothly in the cloud-native world.
History of The Prom King Fun Version
Prometheus — The Prom King
The Legendary Tale of Prometheus at Cloudville High: In the chaotic halls of Cloudville High, the microservice students were out of control, forming cliques and causing havoc. The teachers (aka developers) were losing their minds trying to keep order. The old hall monitors (those outdated monitoring tools) were as effective as a chocolate teapot — by the time they reported a problem, the cafeteria was already a mashed potato war zone.
Enter Prometheus, the Prom King: Prometheus wasn’t just any new kid; he was the cool tra
nsfer from SoundCloud High with a special talent — he knew when trouble was about to start. Instead of waiting for the fire alarm, Prometheus was in the halls, checking on the jocks (servers), nerds (databases), and artsy kids (containers) before mischief could unfold.
The Rise of the Prom King: Prometheus’s journey began at SoundCloud High, where chaos reigned and the old methods weren’t cutting it. The teachers called in Prometheus, who didn’t just wait for problems — he sniffed them out early. Soon, everyone knew Prometheus was the go-to guy to keep the cafeteria from turning into a disaster zone.
Why Prometheus Won the Prom King Crown: Prometheus turned Cloudville High from a disaster into a smooth operation. While old hall monitors were filing reports after the fact, Prometheus was already preventing food fights. His secret? PromQL, a language that let him ask the right questions at the right time, stopping trouble before it even started.
The Prom King’s Winning Strategy: Prometheus wasn’t about sitting back and waiting. He knew Cloudville High was unpredictable, so he took a proactive approach. By regularly checking in on everyone, he kept tabs on all the drama and made sure no one was starting a flash mob in the gym without his knowledge.
Prometheus’s Royal Duties: Now the reigning prom king, Prometheus rules the school. Whether it’s tracking down the class clown or keeping the dance floor from turning into a mosh pit, he’s got it covered. Prometheus has become the linchpin of Cloudville High, ensuring every service behaves and every party rocks.
Before understanding Prometheus We will try to understand some necessary prerequisites Observability and Monitoring.
OBSERVABILITY AND MONITORING
Observability The ability to understand the internal state of a system by analyzing its outputs (logs, metrics, traces).
Monitoring The process of collecting, analyzing, and acting on predefined metrics and logs.

The Hilarious Coffee Shop Chronicles
Scenario: You run “Java the Hut,” a quirky little coffee shop where everything from the espresso machine to the muffin display has a mind of its own. You’re determined to keep the place running like a well-oiled (or well-brewed) machine, but chaos is always lurking around the corner.
Monitoring: The Clueless Security Guard
What It Is: Monitoring is like having Bob, the clueless security guard, who’s great at staring at specific things but not so great at connecting the dots. Bob’s job is to keep an eye on the entrance, the cash register, and the muffin display, and he has a walkie-talkie to alert you when something goes wrong.
How It Works: Bob’s trained to shout into the walkie-talkie when specific things happen. “Hey boss, the muffin tray’s empty!” or “Uh, we’ve got 20 people lined up for coffee, and it’s looking like a zombie apocalypse out here!”
Example: Bob’s walkie-talkie crackles: “No more coffee in the pot! Panic!” You rush out to refill it, but Bob doesn’t know why everyone is grumbling while they wait.
Limitation: Bob can tell you something’s wrong, but he’s not exactly Sherlock Holmes. If the shop’s quieter than usual, Bob’s just scratching his head, unaware that the coffee tastes like burnt rubber today.
Observability: The Gossiping Barista Brigade
What It Is: Observability is like your team of baristas, who double as the nosiest bunch of people on the planet. They know everything — what’s happening, why it’s happening, and who’s to blame (usually Steve, the part-time barista who forgets to clean the espresso machine).
How It Works: Your baristas (logs, metrics, traces) don’t just make coffee; they’re like your own personal intelligence agency. They overhear customer complaints, notice trends (like when that hipster in the corner switches from a double espresso to a matcha latte), and can tell you exactly why today’s muffin sales are tanking.
Example: “Psst,” whispers one barista, “everyone’s leaving because the coffee tastes like motor oil today. Steve must’ve used the decaf beans by mistake.” Not only do they spot the problem, but they also give you the dirt on why it’s happening. Thanks to them, you’re not just putting out fires — you’re preventing them.
Advantage: With your baristas’ keen observations, you can prevent disasters like “Muffinageddon 2024” before they happen. You know the why behind the chaos, so you can fix it with a smile (and a free coffee voucher to keep customers happy).
