* Add procmon plugin with live process panel New Noctalia plugin: bar widget shows CPU/RAM usage and process count; floating panel has a sortable, searchable process table with per-process kill. Background service samples ps and /proc stats and publishes via plugin state. * Throttle data-driven panel renders Rebuild table at most every 500ms to stay within the panel update CPU budget. User interactions still render immediately; only state watches and the tick go through maybeRender(). * Update procmon deps and fix timestamp precision Document head, grep, and cat as required commands. Correct refresh interval default to 1000 ms. Sample refreshedAtMs in milliseconds. * Add keyboard navigation and reduce CPU sampling - Panel: arrow keys move cursor, Ctrl+D kills selected, Ctrl+F focuses filter - Service: sample /proc stats every 1s, ps every 2s; 2s render floor - Widget: handle vertical bars, truncate text, use valid theme color - Bump version to 0.4.0, plugin_api 13
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:
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
psevery 2nd refresh interval (the process table changes slowly) and reads/procstats every interval;runAsyncruns the configuredkill_commandwhen 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_commandwhen a row's ✕ is clicked. -
Requires
plugin_api = 13. 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.
