评估网络Java应用程序的性能

Question

We want to automatically measure performance of our Java product.

We want to have following metrics:

• Processor loading
• Memory loading
• Network loading
• Project related metrics

We want to run those performance tests continuously on Jenkins server. Project related performance metrics and system metrics above, will be displayed as some trend graphs.

Could you please suggest a Java performance framework or maybe, approach, to measure system metrics automatically?

I found a list of open source performance test tools and considering to use JMeter Java Sampler and running it from Java code. But I am not familiar enough with JMeter and not sure that this is a proper choice.

Answer 1

You will likely want to use some kind of JMX monitoring / profiling tool, such as VisualVM, https://visualvm.java.net/ . It gives detailed processor load, memory load (split by JVM memory pool), and you can extend it to add your own metrics by writing custom MBeans in your code.

I worked on building a monitoring webapp at a previous job - it periodically collected information from servers via JMX, and pinged that information to a Graphite instance so we could track the metrics over long time periods. You could consider doing a similar thing. VisualVM is a good interim solution though.

Answer 2

JMeter is a good choice as it's free and open source, it can scale, it is Java-based and can be easily added as a task to CI process.

1. JMeter PerfMon Plugin - Servers Performance Monitoring reporting CPU, RAM, Network and Disk IO
2. There is a JMeter Jenkins plugin providing native integration of JMeter tests into continuous build process
3. JMeter tests can be launched as OS command-line task, Ant task, Maven plugin, from Java code and you can use JMeter API to build and execute the test on the fly. See 5 Ways To Launch a JMeter Test without Using the JMeter GUI guide for details.
