Kubernetes is an open-source container orchestration framework. It helps teams to automatically deploy, scale, and manage large fleets of containers. However, it brings with it a whole new set of challenges when it comes to troubleshooting and debugging.

Containerized applications are different from traditional applications — they are packaged in pods, and these pods are randomly created and destroyed throughout the app’s lifecycle. Therefore conventional methods of troubleshooting often fail to deliver the best results.

In this guide, we highlight a newer tool called Komodor, a Kubernetes-native troubleshooting tool, that aims to solve these problems. We will discuss how Komodor works, why you should opt for it, and what other options might be alternative to Komodor.

How Does Komodor Work?

Komodor is a troubleshooting and monitoring tool for your Kubernetes clusters. It integrates with your clusters and keeps an eye on the health of each component. You can integrate it with a variety of third-party tools to keep yourself in the loop. It also generates detailed statistics and visualization on your cluster’s performance for you to analyze and make decisions.

Key Features

Komodor offers an array of key features to help you track and troubleshoot your K8s clusters easily. The first feature to catch the eye is the events section.

Komodor tracks all events that occur in your Kubernetes clusters and stacks them against time to show you a histogram of what’s been happening with your clusters. The events are quite detailed in themselves.

For instance, if you encounter an unhealthy service, this is what the event notification would look like:

You can add integrations to Slack and other services via Links to add more metadata about your issues and send out alerts as needed.

Installation & Support

Komodor is one of the simplest tools to get started with. The initial setup process is a breeze, and setting up hardly takes around 5 minutes. All you need to do is to name your cluster and run a set of pre-generated commands from Komodor on your cluster to set up the connection between the two.

As soon as you run the commands, Komodor automatically listens and connects to your cluster. It discovers available services and starts monitoring them instantly.

Komodor also provides customer support via chat for users struggling with their first few steps. While it is not the most instant experience, it sure complements the good amount of documentation provided by the team.

User Interface & Ease of Use

The user interface of the tool is quite intuitive, simple, and self-explanatory. Major sections of the tools are arranged under a list of tabs, including services, jobs, events, alerts, and more. The events page carries a lot of information about the various events occurring in your clusters but organizes it well to avoid visual noise.

The integrations and notifications section both concisely list out the relevant data making it easy for you to get started as well as view old data easily.

Third-party Integrations

Komodor offers a limited range of third-party integrations to help make your life easier. You can easily set up your Kubernetes cluster, link its repo, and connect to a Slack channel for sending out event-related alerts. You can also connect with other tools like Sentry, OpsGenie, DataDog, etc., for incident management.

Pricing

Komodor’s pricing is simple and straightforward. There’s a plan called Team that offers support for up to 250 nodes, for $10 per node per month. If your workload is greater than that, you can set up a call with them to discuss your pricing.

They also offer a fully functional free trial to understand and experience the tool in your projects before making a commitment. You do however need to book a demo with a member of the team before activating your trial.

Why Should You Use Komodor?

There are a number of reasons why you should use Komodor for native Kubernetes troubleshooting.

Easy To Get Started With

Given that Komodor is a full-fledged troubleshooting tool for complex Kubernetes clusters, it is quite simple to get started with. The installation process is simple, and it automatically generates the commands you need to get started.

The UI is quite intuitive, and you can easily find your way around it. There are a number of guides and tutorials to help you get going once you’re set up.

Third-party Integrations

One of the largest selling points of Komodor is that it offers integration with a wide array of third-party software. You can connect your code hosting provider, such as GitHub or GitLab, to generate code-level annotations automatically. If your team uses a dedicated tool for incident management such as PagerDuty or OpsGenie, you can have Komodor send incident details to them directly.

You can also set up alerts via New Relic or send them directly into your Slack channels. Komodor integrates with Grafana easily to create simple visualizations. All in all, signing up for Komodor will keep you well-connected with the rest of your tech stack.

Cost and Consumption Optimization

Komodor enables you to build a comprehensive view that includes details about relevant deploys, configuration changes, service alerts, and more. The biggest benefit of using a troubleshooting tool such as Komodor is the cost optimization that it brings with itself. With regular updates on the downtimes of your cluster’s services, you can fix them to help reduce the impact on your end-users.

4 Alternatives to Komodor

If you are unsure if Komodor would be the right fit for your K8s app, consider giving it a try with its 14-day free trial. If things don’t work out well, fret not! Here are a few other tools you could consider to replace Komodor.

ContainIQ | A SaaS or On-Prem Alternative

ContainIQ is a Kubernetes native monitoring and tracing platform. Included in the platform, ContainIQ offers a number of tools for debugging and troubleshooting problems that come up.

Like Komodor, ContainIQ offers a view of the Kubernetes events feed and users are able to alert on all event types, including both Normal and Warning events.

Kubernetes events dashboard

ContainIQ makes to easy to click from a particular event to the logs at that point in time. This is particularly helpful when troubleshooting. For example, a user could click directly from a CrashLoopBackoff to the logs and metrics at that point in time. ContainIQ also offers a diagnostic and health dashboard which is helpful for getting a quick view of overall cluster health.

ContainIQ’s health dashboard is currently in beta and should be available to all users shortly. Finally, ContainIQ offers a logging dashboard to view all application and cluster level logs, a tracing dashboard to view internal and external requests, and metrics dashboards to view pod and node metrics.

ContainIQ charges $20 per node per month, plus $0.50 per GB of log ingest. ContainIQ is available as both a SaaS and an on-prem offering.
