TRACER

Monitor live application either as child process or separate PID, collecting /displaying stats ( cpu usage, memory usage).

Note: For monitoring one-shot applications - see https://github.com/yarenty/appbenchmark._

CLI

Build

shell cargo build -r --bin tracer

Usage

```shell app-tracer 0.1.0 Tracing / benchmarking long running applications (ie: streaming).

USAGE: tracer [OPTIONS] [APPLICATION]

ARGS: Application to be run as child process (alternatively provide PID of running app)

OPTIONS: -h, --help Print help information -l, --log Set custom log level: info, debug, trace [default: info] -o, --output

Name of output CSV file with all readings - for future investigations [default: output.csv] -p, --pid PID of external process -r, --refresh Refresh rate in miliseconds [default: 1000] -V, --version Print version information

```

Example output

log 12:20:23.407 (t: main) INFO - tracer - Application by PID to be benchmark is: 5344 12:20:23.408 (t: main) INFO - tracer - Refresh rate: 1000 12:20:23.408 (t: main) INFO - tracer - Starting with PID::5344 12:20:24.493 (t: main) INFO - tracer - CPU: 0, MEM: 3780952064 12:20:25.498 (t: main) INFO - tracer - CPU: 6.6926346, MEM: 3780952064 12:20:26.500 (t: main) INFO - tracer - CPU: 7.279213, MEM: 3780952064 12:20:27.505 (t: main) INFO - tracer - CPU: 6.3983507, MEM: 3780952064 12:20:28.510 (t: main) INFO - tracer - CPU: 7.1348634, MEM: 3780952064 12:20:29.514 (t: main) INFO - tracer - CPU: 7.176454, MEM: 3780952064

TUI

Build
