Upsun Continuous Profiler is powered by Blackfire. It is available directly the Console, under the Profiling tab of your environments.
The Java continuous profiling is currently made across 3 dimensions:
- CPU Time: Time spent running on the CPU
- Allocations: Time spent running on the CPU
- Allocated Memory: Number of bytes allocated
The default sampling frequency is 100 Hz. This means the Java continuous profiler is collecting information 100 times per second.
Prerequisites 
Upsun Continuous Profiler requires Java >= 17.
Configuration
The Java continuous profiler is enabled by default without configuration.
