How do you plan a JVM performance tuning?
How to Properly Plan JVM Performance Tuning
- Understand the JVM garbage collector.
- Be familiar with the common tools for JVM performance monitoring.
- Have the ability to read GC logs.
- Perform tuning only when necessary and practical (JVM performance tuning cannot solve all performance problems)
What is JVM tuning?
JVM tuning mainly involves optimizing the garbage collector for better collection performance so that applications running on VMs can have a larger throughput while using less memory and experiencing lower latency.
What are JVM tools?
The best JVM monitoring tools
- AppOptics (FREE TRIAL) AppOptics is a cloud-based service that operates both infrastructure and application monitoring.
- ManageEngine Applications Manager.
- Site24x7 APM.
- Datadog APM.
- Sematext Monitoring.
- Dynatrace.
What is JVM monitoring and why is it important?
The JVM is a complex process that requires monitoring for several key metrics that indicate the health and performance of your running application. APM tools can make this task a lot easier by recording data on the most important metrics and displaying it in a helpful format that’s more convenient to read and interpret.
How can I improve the performance of my JVM application?
Elasticsearch and Apache Solr are two of them. In such cases, leaving more memory for the operating system will be beneficial for overall JVM performance. And, of course, the heap is not everything. The JVM-based application can also use off-heap memory.
What is JVM tuning and why is it important?
Either way, the goal of JVM tuning is to optimize the garbage collector so that you have high throughput with less memory consumption and low latency. However, less memory/low latency does not automatically mean that the less or lower the memory or latency is, the better the performance.
What is the CPU utilization of the JVM?
In the graph above, the CPU utilization is less than 1\% so there is no reason for concern. Of course, you can set monitors for each of these metrics in the same way as the JVM memory monitor. The JVM is a complex process that requires monitoring for several key metrics that indicate the health and performance of your running application.
