| # Explore the memory usage |
| |
| `ffx profile memory` is a tool to explore the RAM usage of a Fuchsia system. |
| It works by evaluating how much commited memory is used by VMOs on the system, regardless of whether these VMOs are mapped or not (unlike `ps`). |
| |
| ### Getting the raw data |
| |
| Under the hood, this tool uses the component `memory_monitor` to capture information on all the VMOs of the system. |
| |
| You can get the raw data exported by `memory_monitor` with the option `--debug-json` |
| |
| ### Measuring data over time |
| |
| You can track the memory usage over time by combining the `--csv` and `--interval` options, for example: |
| ``` |
| ffx profile memory --csv --interval 1 |
| ``` |
