Example

// Create a new CPU profiler with a sampling frequency of 1000 Hz and an empty ignore list.
let cpu = scuffle_pprof::Cpu::new::<String>(1000, &[]);

// Capture a pprof profile for 10 seconds.
// This call is blocking. It is recommended to run it in a separate thread.
let capture = cpu.capture(std::time::Duration::from_secs(10)).unwrap();

// Write the profile to a file.
std::fs::write("capture.pprof", capture).unwrap();

Analyzing the profile

The resulting profile can be analyzed using the pprof tool.

For example, to generate a flamegraph:

pprof -svg capture.pprof
