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 Anchor to this heading

Upsun Continuous Profiler requires Java >= 17.

Configuration Anchor to this heading

The Java continuous profiler is enabled by default without configuration.
