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.

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.

Monitoring Druid with Prometheus

Druid Exporter – A Prometheus agent for Druid Database

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.

Opstree’s Logging (EFK) Operator

Logging is a critical part of monitoring and there are a lot of tools for logs monitoring like Splunk, Sumologic, and Elasticsearch, etc. Since Kubernetes is becoming so much popular now, and running multiple applications and services on a Kubernetes cluster requires a centralized, cluster-level stack to analyze the logs created by pods.
One of the well-liked centralized logging solutions is the combination of multiple opensource tools i.e. Elasticsearch, Fluentd, and Kibana. In this blog, we will talk about setting up the logging stack on the Kubernetes cluster with our newly developed operator named “Logging Operator”.

Redis Setup on Kubernetes

Redis is a popular and opensource in-memory database that supports multiple data structures like strings, hashes, lists, and sets. But similar to other tools, we can scale standalone redis to a particular extent and not beyond that. That’s why we have a cluster mode setup in which we can scale Redis nodes horizontally and then distribute data among those nodes.

Since Kubernetes is becoming buzz technology and people are using it to manage their applications, databases, and middlewares at a single place. So in this blog, we will see how we can deploy the Redis cluster in production mode in the Kubernetes cluster and test failover.
