A Fun and Easy Guide to Monitoring and Observability With Prometheus

Hi Guys !! I am back with another interesting blog where we learn the concepts but in a funny and easy way.

What is Prometheus ?

Boring Version 💤💤

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.

Integration of Prometheus with Cortex

As we promised in our previous blog Prometheus as Scale – Part 1 that in our next blog we will be writing about the implementation part of Cortex with Prometheus, so here we are with our promise. But before going to the implementation part, we would suggest you guys go through our first blog to know the need for it.

Previously we talked that Prometheus is becoming a go-to option for people who want to implement event-based monitoring and alerting. The implementation and management of Prometheus are quite easy. But when we have a large infrastructure to monitor or the infrastructure has started to grow you require to scale monitoring solution as well.

A few days back we were also in a similar kind of situation where one of our client’s infrastructure was growing as per the need and they need a resilient, scalable, and reliable monitoring system. Since they were already using the Prometheus, so we explored our option and came across an interesting project called “Cortex“.

Four Main Metrics of Prometheus

Let’s first understand what Prometheus is:

Prometheus is an open-source monitoring solution built primarily for gathering and analyzing time-series data, with specific built-in tools making it appropriate for monitoring Kubernetes and other containerized environments. It is a cross-platform monitoring tool that lets you collect metrics from servers, containers, and applications and work with them all in the same way.

Now let’s understand Prometheus Architecture to know how it works:

Prometheus is a multi-component system. While the following integrates into a Prometheus deployment, there is flexibility in which of these pieces are actually implemented.

Prometheus-Alertmanager integration with MS-teams

As we know monitoring our infrastructure is one of the critical components of infrastructure management, which ensures the proper functioning of our applications and infrastructure. But it is of no use if we are not getting notifications for alarms and threats in our system. As a better practice, if we enable all of the notifications in a common work-space, it would be very helpful for our team to track the status and performance of our infrastructure.
