Containers are no longer a thing of the future – they are all around us. Companies use them to run everything – from the simplest scripts to large applications. You create a container and run the same thing locally, in the test environment, in QA, and finally in production. A stateless box built with minimal requirements and unlike virtual machines – without the need of virtualizing the whole operating system.

At Sematext, we are dedicated to making troubleshooting easier for ops teams. When we started to receive positive reviews from our customers around the globe, we knew we were doing something right.

In this post, we’re delighted to announce that Sematext Cloud is featured in the G2 Spring 2022 Reports under Monitoring Software Solutions category as.

There are multiple reasons why Java and the Java Virtual Machine-based languages are very popular among developers. A rich ecosystem with lots of open-source frameworks that can be easily incorporated and used is only one of them. The second, in my opinion, is the automatic memory management with a powerful garbage collector. The Java garbage collector, or in short, the GC, takes care of cleaning up the unused bits and pieces.

HAProxy is one of the most popular software around when it comes to load balancers and reverse proxies. When you’re using it for these purposes, it’s especially important to monitor for both availability and performance, which will impact your SLI and SLOs. In this post, we’ll talk about the main HAProxy metrics you should monitor and the best monitoring tools you can use to measure them.

In this article, you’ll learn how to understand and debug the memory usage of a Node.js application and use monitoring tools to get a complete insight into what is happening with the heap memory and garbage collection. Here’s what you’ll get by the end of this tutorial. Memory leaks often go unnoticed. This is why I suggest using a tool to keep track of historical data of garbage collection cycles and to notify you if the heap memory usage starts spiking uncontrollably.

All the applications that you’re trying to execute require memory. It doesn’t matter if the application was developed using assembly language. Or if you used a low-level programming language like C or a language compiled to a bytecode like Java. Running the application requires memory for the code itself, the variables, and the data that the code processes. Depending on your usage, the memory requirements will vary.

It’s virtually impossible to manage today’s complex IT environments at scale without a comprehensive system monitoring solution that allows you to check the health of all your applications and services from a single pane of glass. When your end users are experiencing difficulties, you must have such a tool in place that lets you quickly ascertain and remediate the root cause of the slowdown or error.

“Solr or Elasticsearch?”…well, at least that is the common question we hear from Sematext’s consulting services clients and prospects. Which one is better, Solr or Elasticsearch? Which one is faster? Which one scales better? Which one is easier to manage? Which one should we use? Is there any advantage to migrating from Solr to Elasticsearch? – and the list goes on.

There are a lot of reasons why people choose to shop at one online store over another or pick one streaming service over another from the type of service they are getting to pricing, quality and, you’ve guessed it from the title, speed. The speed to which I’m referring is the speed at which the website loads and reacts to user input. In one of my previous articles about netwok latency, I’ve talked about how big of a difference even a two-second extra delay makes.
