Monitoring is not easy. Period. In our guide to Kubernetes monitoring we explained how you need a different approach to monitoring Kubernetes than with traditional VMs. In this blog post, we’ll go into more detail about the key Kubernetes metrics you have access to and how to make sense of them. Kubernetes is the most popular container orchestrator currently available. It’s available as a service across all major cloud providers. Kubernetes is now a household name.

Log management stopped being a very simple operation quite some time ago. Long gone are the “good old days” when you could log into the machine, check the logs, and grep for the interesting parts. Right now things are better. With the observability tools that are now a part of our everyday lives, we can easily troubleshoot without the need to connect to servers at all. With the right tools, we can even predict potential issues and be alerted at the same time an incident happens.

It shouldn’t come as a surprise that website speed is important to your viewers. It’s the first thing they experience after accessing your website. Your website speed is like an unsung hero that you don’t really notice when it works the way it should, but the second it doesn’t live up to the expectations of your users, they will immediately notice it.

Nowadays, most applications we build are composed of microservices and distributed in nature. In such a setup, communication between these microservices is crucial, but can, unfortunately, cause some headaches. The first thing I check when I’m troubleshooting a bug in production is inter-service communication. Having a reliable tool at your disposal to take care of this can reduce a lot of stress. RabbitMQ, a hybrid messaging broker, is one such tool.

Logging is a crucial part of the observability of your Java applications. Combined with metrics and traces gives full observability into the application behavior and is invaluable when troubleshooting. Logs, combined with metrics shortens the time needed to find the root cause and allows for quick and efficient resolutions of problems.

Troubleshooting issues in your applications can be a complicated task requiring visibility into various components. In the worst-case scenario, to understand what is happening and why it is happening you will need metrics, logs, and traces combined together. Having that information will give you the possibility to slice and dice the data and get to the root cause efficiently. In this article, we will focus on logs and how to configure logging for your Java applications.

When it comes to troubleshooting application performance, the more information you have the better. Logs combined with metrics and traces give you full visibility into your Java applications. Logging in your Java applications can be achieved in multiple ways – for example, you can just write data to a file, but there are far better ways on how to do that, as we explained in our Java logging tutorial.

A user looking for “awesome smartphone 2018” is likely really after “+review:awesome +category:smartphone +release_date:2018”. A clever use of (e)dismax might get us pretty close to where we want, but it’s not real query understanding. There are other ways, of course, like training a model that will, based on the keyword, guess which field it’s looking into.

Your software stack likely consists of web servers, search engines, queues, databases, etc. Each part of your stack emits its own metrics and logs. Depending on the size of your team and structure, different team members might have permissions to look at one set of data, but not the other. Some data is needed for troubleshooting and can be discarded after just a few days, while more important data might need to be kept for months for legal or capacity planning purposes.
