precord

Command line tool for recording process or system performance data.

Installation

Install with cargo:

shell cargo install precord

Usage

shell precord -p 1203 -o result.svg

Options

shell precord -h

• -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
  • net_in/net_out - Network recv/send of process
  • sys_cpu_freq - CPU frequency of system
  • sys_cpu_temp - CPU temperature of system
  • sys_gpu - GPU 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

precord-core

A library for retrieving process and system performance data.

```rust 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(cpuusage) = system.processcpuusage(1203) { println!("Process({}) %CPU: {:.2}%", 1203, cpuusage) }

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

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