Command line tool for recording process or system performance data.

Installation

Install with cargo:

cargo install precord

Usage

precord -p 1203 -o result.svg

Options

precord -h

• -c / --category - categories for recording, possible values:
  • cpu - CPU usage of process
  • mem - Memory usage of process
  • alloc - Allocation of process
  • gpu - GPU usage of process
  • vram - VRAM usage of process
  • fps - Frame rate of process
  • net_in/net_out - Network recv/send of process
  • disk_read/disk_write - Disk read/write of process
  • kobject - Kernel object count of process
  • sys_cpu - CPU usage of system
  • sys_cpu_freq - CPU frequency of system
  • sys_cpu_temp - CPU temperature of system
  • sys_gpu - GPU usage of system
  • sys_power - Power usage of system
• -p / --process - ID of processes
• --name - Name of processes
• -o / --output - Specify the output file, possible extensions:
  • .svg
  • .html
  • .json
  • .csv
• -i / --interval - Interval for recording
• -n - Count for recording
• --time - Time limit for recording, e.g., --time 1h30m59s
• -r / --recurse-children - Flag to recurse child processes
• --skip - Number of skip records
• --gpu-calc - Gpu calculation, possible values:
  • max
  • sum

Command Mode

Type : during recording will enter the command mode, and press Esc will back to recording. The supported commands are:

• w - Write(Save) output
• q - Exit
• wq - Combination of w and q
• time - modify time limit for recording

Sub Commands

• thread-list <PID> - List threads and cpu usage

precord-core

A library for retrieving process and system performance data.

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

fn main() {
  let mut system = System::new(Features::PROCESS || Features::GPU, [1203]).unwrap();
  thread::sleep(Duration::from_secs(1));
  system.update();

  if let Some(cpu_usage) = system.process_cpu_usage(1203) {
    println!("Process({}) %CPU: {:.2}%", 1203, cpu_usage)
  }
  
  #[cfg(target_os = "windows")]
  if let Some(gpu_usage) = system.process_gpu_usage(1203, GpuCalculation::Max) {
    println!("Process({}) %GPU: {:.2}%", 1203, gpu_usage)
  }
  
  if let Some(sys_gpu_usage) = system.system_gpu_usage(GpuCalculation::Max) {
    println!("System %GPU: {:.2}%", sys_gpu_usage);
  }
}
