But, the overall benefits of this Kubernetes function outweigh its challenges. Knowing Kubernetes in-depth and using the right Kubernetes tools can remove hurdles while tracking the overall health of your applications and infrastructure.

What Is Kubernetes Monitoring? #

Before choosing a Kubernetes Monitoring Tool, you first need to know what Kubernetes Monitoring refers to. In simple terms, Kubernetes Monitoring means ensuring your tech stack, code, and all your apps are running smooth and fine after gathering events and metrics from your clusters.

The most effective monitoring refers to centralizing all this data in a single location where multiple the people involved can gain actionable insights.

The process of monitoring, analyzing and centralizing the data can be cumbersome because of the different complex layers that come with running containerized apps and Kubernetes.

But, the popularity of Kubernetes gradually increased due to corresponded with advanced tools and services. This also includes various commercial and open source tools that make Kubernetes Monitoring more effective.

Here’s a list of some popular Kubernetes Monitoring tools.

Prometheus #

Prometheus is one of the most popular Kubernetes tools and recently gained a foothold as a fan favorite because of its out-of-the-box event-monitoring what it can do. Prometheus offers many options for flexibility and customizability to its users that no commercial tool provides.

It joined Cloud Native Computing Foundation (CNCF) in 2016 and has become one of the market’s most established event-monitoring and alerting tools. Also, it’s the second hosted project after Kubernetes.

Grafana #

Grafana is a popular open source platform after Prometheus that offers advanced features for Kubernetes monitoring. Grafana thrives as an intelligent monitoring tool for visualization, event monitoring and metric analytics.

The best part about this tool is it can work smooth with monitoring software like Prometheus to form a one-two punch for Kubernetes visualization and monitoring. You can get great insight into your Kubernetes instance by deploying both tools.

Thanos #

Thanos is back with the snap. this time it’s designed to make centralizing your Prometheus-based monitoring systems easy in one snap. This tool is used to remove all Prometheus challenges that arrive while scaling Prometheus during Kubernetes Monitoring.

Thanos is an open-source software tool to transform your existing Prometheus deployments into a unified monitoring system by centralizing your data.

Elasticsearch #

Elasticsearch is an analytics-type search engine with flexibility and scaling features, due to which it has become a great choice to use with Kubernetes.

Logstash #

Logstash is one of the most potent options to help centralize your data. It’s an open-source software tool with server-site data-processing pipeline what it does. It takes your data from different available sources and then transforms it.

Kibana #

Kibana is a powerful tool for data visualization and also for time-series analytics. After its recent update, it can now be used for monitoring and intelligence.

Choosing the Right Tools #

With different choices, there comes more confusion- deciding which is the right tool for your company. If that is worrying you, the answer is quite simple- it depends on your company’s needs.

But before making any choice, it’s essential to look at your Kubernetes role down the road in the future along with the current environment.

To maintain streamlined operations and gather maximum information from your monitoring and analytics, you must choose a good monitoring approach capable of scaling your company’s growth.

For example, Suppose an company demands data from software and hardware sources. In that case, they use a combination of Prometheus and Grafana for event and application monitoring. Grafana is a powerful tool for visualizing actionable data and gathering time-series data from software and hardware sources.

But, scaling Prometheus across many clusters is challenging significantly when the company is rapidly growing. A rapidly growing company invites hurdles in in-app boarding, drift, and managing configuration requirements. If your company is operated in a multicluster environment, you can switch to a powerful tool like Thanos.

Using Thanos in a multicluster environment provides long-term storage and allows you to aggregate data. The final result is much more flexible with the combination of Prometheus and Grafana.

Moreover, you can also combine Elasticsearch with Kibana and Logstash, as they work smooth and are more effective with Kubernetes. This combination is also known as an ELK stack or Elastic Stack. This creates a great way to organize, collect, visualize and search your data to provide visibility for your Kubernetes clusters and end-to-end monitoring.

Conclusion #

Using a platform approach for your Kubernetes-monitoring needs is an excellent move, and after knowing the available tools with their roles, it becomes smooth too. The best thing about using tools for your Kubernetes Monitoring is that it works toward gaining broad visibility into your applications and systems. Adding tools, you also get the most out of Kubernetes and eventually set up IT for sustained success.
