ZGC, or Z Garbage Collector, is a modern garbage collection algorithm introduced in Java 11. It was designed to handle very large heap sizes with extremely low pause times. ZGC aims to keep pause times under 10 milliseconds, even with heaps sized in terabytes. For beginners, ZGC might sound complicated, but this article breaks it … Read more
The Concurrent Mark Sweep (CMS) Garbage Collector was a popular garbage collection algorithm used in the Java Virtual Machine (JVM) for many years. It was introduced to reduce long pause times caused by Full GCs. Although it has been deprecated in newer Java versions (starting from Java 9 and removed in Java 14), many applications … Read more
The G1 Garbage Collector (G1GC) is one of the most advanced garbage collection algorithms in the Java Virtual Machine (JVM). It is also called Garbage-First Garbage Collector. It was designed to handle large heap sizes and to meet the needs of modern Java applications. Introduced in Java 7 as an experimental feature and made default … Read more
Synthetic Monitoring is a technique that continuously simulates user interactions with a system or application to test its performance and availability. It is also known as proactive monitoring. Unlike Real User Monitoring (RUM), which tracks actual user behavior, synthetic monitoring operates in a controlled environment, generating traffic at regular intervals to identify issues before end-users … Read more
APM (Application Performance Monitoring) vs RUM (Real-User Monitoring) In the rapidly evolving world of web and application development, maintaining optimal performance and a smooth user experience is critical. Two of the most widely used monitoring strategies are Application Performance Monitoring (APM) and Real User Monitoring (RUM). While both aim to enhance application reliability and performance, … Read more
To measure CPU utilization in a cloud-based architecture, or, to be specific, in a cluster (e.g., a Kubernetes cluster, Hadoop cluster, or any distributed system), you need to monitor CPU usage across all nodes in the cluster. Some people might be unaware of the cluster. A cluster is a collection of servers (virtual or physical) … Read more
