Prometheus at Scale – Part 1

Prometheus has gained a lot of popularity because of its cloud-native approach for monitoring systems. Its popularity has reached a level that people are now giving native support to it, while developing software and applications such as Kubernetes, Envoy, etc. For other applications, there are already exporters(agent) available to monitor it.

Since I have been working on Prometheus for quite a long time and recently have started doing development on it, I was confident that I can handle any kind of scenario in it. Here, in this blog, I am going to discuss a scenario that was a very good learning experience for me.

A while back we got the requirement for working on Apache Druid. By working on Apache Druid, We mean setup, management, and monitoring. Since it was a new topic for us we started evaluating it and we actually find it has a lot of amazing features.

So for the people who don’t have an idea about Druid and just starting with Druid. Let me give a quick walk-through of it.

Elasticsearch Cluster Monitoring

Elasticsearch is a scalable, full-text search and analytics engine based on Apache Lucene. It is Java-based and allows you to store, search, and analyze big volumes of data quickly in near real-time. It can search and index the document files in diverse formats. Lucene is the underlying technology that Elasticsearch uses for extremely fast data retrieval.

As flexible, scalable, and useful as Elasticsearch is, monitoring your cluster can help you ensure that the cluster is appropriately sized and handles all operations efficiently.

Why APM is Extremely Significant!

We all have faced the problem when the system gets too slow. Have you wondered why this problem occurs? Well, there could be several reasons but one of them is application performance. In today’s time, the term application has become very large and complex. Users using these applications often choose different mediums, as they have separate goals and requirements as per their needs.

This diversity in consumption medium brings complexity in a configuration which is only increasing in today’s time. Application performance means how available your application is for this real-world which brings us to APM. In this blog, first of all, we will discuss, what is APM, why it is needed, and what are the APM tools, which can help us obtain the information and health of the system.
