Our Garbage collection log analysis REST API provides powerful micrometrics. Using these micrometrics, you can predict and forecast the application’s availability and performance characteristics.
JVM is the most popular programming platform in the world. It empowers thousands of enterprises to run their mission-critical applications. However, tuning, optimizing and troubleshooting JVM is not a trivial job.

Recent times, Uber has been experiencing exponential growth in its traffic. Recent spike in traffic volume exposed several memory related performance bottlenecks in their platform: long garbage collection (GC) pauses, memory corruption, out-of-memory (OOM) exceptions, and memory leaks. In this brilliant article, the Uber engineering team summarizes their optimization journey: What all the challenges they faced, the tools they used, best practices they followed to fix their application’s performance bottlenecks.

Java Heap fragmentation is an interesting problem, which triggers long pausing full garbage collection cycles. In this article we would like to attempt to explain the heap fragmentation.
Let’s say developer write a code ‘new BMW()’. This will create a new BMW object in the heap memory space. Example:

Since we are analyzing thousands of Garbage Collection logs every single day through our GCeasy tool, we are noticing several java applications still continuing to use ‘-XX:+UseCompressedOops’ JVM argument. Actually, it’s not required to pass ‘-XX:+UseCompressedOops’ JVM argument if you are running in Java SE 6 update 23 and later. Compressed oops is supported and enabled by default in Java SE 6u23 and later versions.

At the time (March 2020) of writing this article there are 600+ arguments that you can pass to JVM just around Garbage collection and memory. If you include other aspects, total JVM arguments count will easily cross 1000+. 😊. It’s way too many arguments for anyone to digest and comprehend. In this article, we are highlighting seven important JVM arguments that you may find it useful.
