* update(procmon): fix windowed table follow-scroll & row sizing` * Update plugin.toml * Update README.md * fix(procmon): always render list body as scroll to stop bottom clipping 0-result search switched the body from ui.scroll to a bare ui.row; when results returned the row->scroll switch left the flexGrow viewport stuck short, clipping bottom rows. Use ui.scroll with a shared key in both branches so the tree keeps one stable scroll node.

# Process Monitor
|
|
|
|
A bottom-style process monitor for Noctalia: live CPU/RAM/swap bars and a
|
|
sortable, searchable process table with a per-process kill action, all in a
|
|
panel. Great for spotting a runaway process or a zombie and killing it without
|
|
opening a terminal.
|
|
|
|
## Plugin
|
|
|
|
| Field | Value |
|
|
| ------- | -------------------------------------------------------- |
|
|
| ID | `weinguyen/procmon` |
|
|
| Entries | Bar widget: `widget`; panel: `panel`; service: `service` |
|
|
|
|
## Requirements
|
|
|
|
Install `ps`, `kill`, `head`, `grep` and `cat` on `PATH` (all are present on
|
|
virtually every Linux distribution).
|
|
|
|
## Usage
|
|
|
|
Add the **Process Monitor** widget to a bar. It shows the current CPU and RAM
|
|
usage (plus the process count). Click the widget to toggle the process panel:
|
|
|
|
```sh
|
|
noctalia msg panel-toggle weinguyen/procmon:panel
|
|
```
|
|
|
|
The panel shows CPU, RAM and swap bars with the 1/5/15-minute load averages,
|
|
then a process table. Sort by the column dropdown (PID, CPU%, MEM%, RSS,
|
|
COMMAND) and flip asc/desc with the arrow button. Type in the filter box to
|
|
match a process by name, user or PID. Click the ✕ button on a row to run the
|
|
configured kill command against that PID (default `kill -TERM`). Zombie
|
|
processes are tinted with the error color so they stand out.
|
|
The table refreshes on the interval set in the `refresh_interval` setting. The
|
|
panel re-renders automatically as new samples arrive, so the view stays live
|
|
while it is open.
|
|
|
|
## Settings
|
|
|
|
| Setting | Type | Default | Description |
|
|
| ------------------ | -------- | ------------ | ------------------------------------------------------------------------------------------ |
|
|
| `refresh_interval` | `int` | `1000` | Process resample interval in milliseconds. (default 1000) |
|
|
| `sort_by` | `select` | `cpu` | Initial sort column when the panel opens (`cpu`, `mem`, `pid`, `cmd`). |
|
|
| `kill_command` | `string` | `kill -TERM` | Command run against a selected PID; the PID is appended. Empty falls back to `kill -TERM`. |
|
|
| `show_count` | `bool` | `true` | Bar widget also shows the total process count. |
|
|
|
|
## Notes
|
|
|
|
- **Spawns processes.** A background service runs `ps` every 2nd refresh
|
|
interval (the process table changes slowly) and reads `/proc` stats every
|
|
interval; `runAsync` runs the configured `kill_command` when a row's ✕ is
|
|
clicked. There is no confirmation dialog, so check the PID before clicking.
|
|
|
|
- The bar widget only renders data the service publishes; it never runs
|
|
commands. The panel runs the configured `kill_command` when a row's ✕ is
|
|
clicked.
|
|
- Requires `plugin_api = 13`. The panel renders a windowed slice of the
|
|
process table and follows the keyboard cursor with edge-follow scrolling
|
|
(window slides only when the cursor pushes past an edge, so scrolling up
|
|
doesn't collapse the page until the top edge is reached). CPU%, RAM%, swap
|
|
and the 1/5/15-minute load averages are sampled from `/proc` (`/proc/stat`,
|
|
`/proc/meminfo`, `/proc/loadavg`) by the service, so they work with no
|
|
separate system-monitor dependency.
