User feedback: '进程比较关键，以下显示太少了，需要继续优化下监控UI'
Process monitor panel was rebuilt:
1. core/monitor.py: 200 -> 500 processes, added PPID / PRI / NICE
New ps fields: pid ppid user pcpu pmem vsz rss stat pri nice etimes times args
Python parser: new fields ppid, pri, nice
2. ui/widgets.py MonitorPanel:
a) Toolbar: search box + sort dropdown (CPU/MEM/PID/start/user/comm)
+ view toggle (Flat / Tree) + CPU% min filter (SpinBox 0-100%)
+ batch kill button
b) Table: 12 columns (Flat) / 13 cols (Tree + indent col)
PID PPID USER CPU% MEM% RSS STAT PRI NI '启动' 'CPU时间' 命令
- Compact row height 20px (was default 30)
- Extended selection (Ctrl/Shift multi)
- Color highlights:
CPU% >=80 red bg+fg bold, >=50 red fg bold, >=20 orange
MEM% >=15 orange bg+fg bold, >=5 orange
STAT: Z orange bg + orange-red fg bold, R green, D purple
NI: negative green, positive orange
- Red bg on EXTREME rows for instant visibility
c) Tree view: builds PPID tree with ├─/└─/│ connectors;
root processes (PID 1) at depth 0, sorted by CPU within siblings.
Useful for 'which process is spawning these things?'
d) Right side panel:
- 进程详情 (QTextEdit dark theme): full PID/PPID/USER/STAT/PRI/NI/
CPU/MEM/RSS/VSZ/etime/cputime, command, parent process name,
child processes list (top 10)
- 🔥 CPU TOP 5 (QListWidget dark): click to jump+select in main table
- 💾 内存 TOP 5 (QListWidget dark): same
e) Right-click menu enhanced:
kill (SIGTERM) | kill -9 (SIGKILL) | batch kill (if multi-select)
| copy PID | copy command | filter by command | view details
f) Batch kill: collects all selected PIDs, runs 'kill p1 p2 p3 ...'
in a single SSH call, then loops 'kill -0' to report survivors.
One confirmation dialog lists top 10 + '还有 N 个'.
g) Status row at bottom: 'Ctrl+A 全选, Shift+点击多选, 右键批量操作'
3. test_process_monitor.py: 5/5 tests pass with 500 rows, tree view,
TOP 5, CPU min filter, etc.
All tests pass: core 6/6 + UI 3/3 + E2E 6/6 + terminal 5/5 + proc 5/5
Build: 57 MB single-file exe.
User asked for process monitoring. Added:
1. core/monitor.py:
- Extended _LINUX_METRICS_SCRIPT with ===PROC=== section
- ps -e -o stat= | awk counts total/running/sleep/disk-sleep/zombie
- ps -eo pid,user,pcpu,pmem,vsz,rss,stat,etimes,times,args
Uses etimes/times (numeric) instead of start/time (string with
spaces) to avoid column-shift bugs. awk joins 10th col onwards
with spaces so comm retains its full command line.
- New empty-dict fields: proc_total, proc_running, proc_sleep,
proc_disk, proc_zombie, processes
- New processes[] array with full per-process fields
2. ui/widgets.py MonitorPanel:
- New _build_proc_summary() - 4-stat overview card (total/running/
sleep/zombie, color-coded)
- New _build_proc_table() - 9-column process list with:
* Search box (multi-keyword AND match across pid/user/stat/comm)
* Sort dropdown (CPU / MEM / PID / start time / user)
* Color-coded CPU% (red >=50%, orange >=20%)
* Color-coded MEM% (red >=10%, orange >=5%)
* Color-coded STAT (red for zombie)
* RSS formatted with format_bytes
* ETIME / TIME formatted as 5d3h / 2h15m / 45s
- _apply_proc_filter() - filter + sort + render in one pass
- _proc_context_menu() - right-click menu:
* kill (SIGTERM) | kill -9 (SIGKILL) | copy PID | copy cmd |
filter by this command
- _proc_kill_selected() / _proc_kill() - sends kill over SSH
with confirmation dialog, shows remote exit code in result
- Splitter: 4 metric cards + proc summary + disk + net on top,
process list on bottom. User-draggable.
3. New test_process_monitor.py (5 tests, all pass):
- Real SSH connection, collects process data
- Renders MonitorPanel with 200 rows
- Tests search filter / sort change / clear
- Tests killing a real sleep process: starts sleep 60, finds it
in the table, calls _proc_kill (with QMessageBox monkey-patched
to auto-yes), verifies remote kill -0 returns 'No such process'
- Also fixed passwords in test_e2e.py + test_terminal.py to match
the working local sshd credentials
All tests pass: core 6/6 + UI 3/3 + E2E 6/6 + terminal 5/5 + proc 5/5
