base on Perf monitoring CLI tool for Apple Silicon # asitop  Performance monitoring CLI tool for Apple Silicon  ```shell pip install asitop ``` ## What is `asitop` A Python-based `nvtop`-inspired command line tool for Apple Silicon (aka M1) Macs. * Utilization info: * CPU (E-cluster and P-cluster), GPU * Frequency and utilization * ANE utilization (measured by power) * Memory info: * RAM and swap, size and usage * (Apple removed memory bandwidth from `powermetrics`) * Power info: * CPU power, GPU power (Apple removed package power from `powermetrics`) * Chart for CPU/GPU power * Peak power, rolling average display `asitop` uses the built-in [`powermetrics`](https://www.unix.com/man-page/osx/1/powermetrics/) utility on macOS, which allows access to a variety of hardware performance counters. Note that it requires `sudo` to run due to `powermetrics` needing root access to run. `asitop` is lightweight and has minimal performance impact. **`asitop` only works on Apple Silicon Macs on macOS Monterey!** ## Installation and Usage `asitop` is a Python-based command line tool. You need `pip` to download and install `asitop`. macOS already comes with Python, to install `pip`, you can follow an [online guide](https://phoenixnap.com/kb/install-pip-mac). After you install `asitop` via `pip`, you can use it via the Terminal. ```shell # to enter password before start # this mode is recommended! sudo asitop # it will prompt password on start asitop # advanced options asitop [-h] [--interval INTERVAL] [--color COLOR] [--avg AVG] optional arguments: -h, --help show this help message and exit --interval INTERVAL Display interval and sampling interval for powermetrics (seconds) --color COLOR Choose display color (0~8) --avg AVG Interval for averaged values (seconds) ``` ## How it works `powermetrics` is used to measure the following: * CPU/GPU utilization via active residency * CPU/GPU frequency * Package/CPU/GPU/ANE energy consumption * CPU/GPU/Media Total memory bandwidth via the DCS (DRAM Command Scheduler) [`psutil`](https://github.com/giampaolo/psutil) is used to measure the following: * memory and swap usage [`sysctl`](https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/sysctl.3.html) is used to measure the following: * CPU name * CPU core counts [`system_profiler`](https://ss64.com/osx/system_profiler.html) is used to measure the following: * GPU core count Some information is guesstimate and hardcoded as there doesn't seem to be a official source for it on the system: * CPU/GPU TDP * CPU/GPU maximum memory bandwidth * ANE max power * Media engine max bandwidth ## Why Because I didn't find something like this online. Also, just curious about stuff. ## Disclaimers I did this randomly don't blame me if it fried your new MacBook or something.
