precord

A command line tool to record process and system performance data.

Installation

Install with cargo:

shell cargo install precord

Usage

shell precord -p 1203 -o result.svg

Options

• -c / --category - categories for recording, possible values:
  • cpu- CPU usage of process
  • mem- Memory usage of process
  • gpu- GPU usage of process
  • fps- Frame rate of process
  • sys_cpu_freq- CPU frequency of system
  • sys_gpu- GPU usage of system
• -p / --process - ID of processes
• --name - Name of processes
• -o / --output - Output of recording result, possible extensions:
  • .svg
  • .json
  • .csv
• -i / --interval - Interval of recording
• -n - Count of recording
• -r / --recurse_children - Flag to recurse child processes

precord-core

A library for retrieving process and system performance data.

```rust use precord_core::{Features, System}; use std::thread; use std::time::Duration;

fn main() { let mut system = System::new(Features::PROCESS || Features::GPU, [1203]); system.update();

thread::sleep(Duration::from_secs(1)); system.update();

if let Some(cpuusage) = system.processcpuusage(1203) { println!("Process({}) %CPU: {:.2}%", 1203, cpuusage) }

#[cfg(targetos = "windows")] if let Some(gpuusage) = system.processgpuusage(1203) { println!("Process({}) %GPU: {:.2}%", 1203, gpu_usage) }

if let Some(sysgpuusage) = system.systemgpuusage() { println!("System %GPU: {:.2}%", sysgpuusage); } } ```
