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.

Codeherent: Automatic Cloud Diagrams Powered by Terraform

Codeherent was founded in the year 2016 by the founding team after they met in Alacrity Foundation, a UK entrepreneurship course, in 2015. The founding team’s main focus was how to improve DevOps with a fast Infrastructure as Code (IaC) review process.

The tool is singularly focused on Terraform and is helping multiple organizations to understand, optimize and review their Cloud Infrastructure in a diagrammatic manner. They recognize the fact that organizations are clambering for DevOps maturity, GitOps centralization, and infrastructure agility.

Resolution of Apt-Key Error

A few days back, when I was trying to install snoopy on my system, I came across an apt-key error. I have faced this error before as well but this time I tried to dig more into the issue. After all, we can’t let the same problem trouble us more than it has to.

When we run into such obstacles, they present good opportunities to break down and understand how things work. We must avail them and become better at our jobs. That being said, we do also have an outstanding community online to help provide solutions with reliable references without getting our hands dirty.

Let’s start with this screenshot of the error I encountered:
