It facilitates the profiling applications that run locally as well as in production.

Detailed profiling and visualization: The profiler should be able to capture detailed metrics and allow for visualizations.īased on our evaluation, we chose Java Flight Recorder (JFR).Low TCO: We did not want to spend big bucks on it.Low overhead: The profiler should be suitable for continuous profiling in production.We evaluated a few options that were commonly used across the industry to perform JVM application profiling, a few notable mentions are: which help the developers in analyzing the applications. The second component uses the metrics/events from the reporter and generates relevant visualizations- these can be time trends, flame graphs, etc.

In a JVM profiler, this component generally looks at the JVM-specific events such as thread samples (which show where the program spends its time), lock profiles, and garbage collection details.

The first component gathers the metrics/events from a running application and logs them to a reporter (generally a file, stream, or downstream application).

Profilers usually consist of two components: It then generates relevant metrics against the same and sends them to a reporter, the reporter can be either a file, stream or a downstream application.

These constructs and operations include object creation, iterative executions (including recursive calls), method executions, thread executions, and garbage collections. The JVM Profiler monitors the java byte-code constructs and operations at the JVM level. JVM Profiling is the process of performing application diagnostics to figure out any performance, memory, or I/O-related bottlenecks that could be plaguing the applications that run on JVMs. In this post, we’ll discuss our approach to profiling JVM applications running in Kubernetes. Although some of them are suitable for production usage, getting them to work in a dynamic environment like Kubernetes is a real challenge. There are plenty of JVM profiling tools available and most of them are geared towards profiling local applications. This is where we need the detailed JVM profiling. We use NewRelic as our primary Application Performance Monitoring (APM) tool, and though NewRelic helps us find whether an application performance issue is actually caused by JVM, it falls short if we want to drill down to find the actual cause within JVM. We, at times, encounter performance issues with these workloads - be it issues around thread contention or frequent major GC cycles causing undesired autoscaling of applications and unnecessary resource usage. A lot of our applications are developed using Java or Kotlin. Also note that screenshot below illustrates Eclipse’s “Run Configurations -> Arguments” tab.At OLX Autos, we run a lot of JVM workloads in our Kubernetes cluster. Locally these options aren’t needed but in this example we’re going to run SampleConsoleServer on a remote testserver. To enable the remote management agent on a Java process we’ll add the following parameters when starting it: - Dcom. It also includes a fully featured JMX MBean browser that you can use to monitor and manage MBeans in the JVM and in your Java application. The tool presents live data about memory and CPU usage, garbage collections, thread activity, and more. The JMX Console is a tool for monitoring and managing a running JVM instance. Java Mission Control uses JMX to communicate with remote Java processes. JMC can also be installed in Eclipse IDE. More plug-ins can easily be installed from within Mission Control. JMC consists of the JMX Console and the Java Flight Recorder. Oracle Java Mission Control has been included in standard Java SDK since version 7u40. Oracle Java Mission Control is a tool suite for managing, monitoring, profiling, and troubleshooting your Java applications.

Note that Java Mission Control is free for use during development and testing but requires a license when used for production purposes. Then we will log some runtime data with Java Flight Recorder and analyze it with Java Mission Control. In this post we’ll be connecting JMC to instance of SampleConsoleServer running on a remote host. This post aims to be more practical presentation. There is already a lot of very good writings available about this subject like this or this one.

This blog post intends to give some insight into what the monitoring and diagnostics tool Oracle Java Mission Control (JMC) is and how it can be used to investigate Java application performance.
