Process Manager
- Sort by CPU, RAM, or GPU usage
- Search by process name, PID, user, or command (
GPU0 / #0 syntax to filter by GPU card)
- Right-click context menu: Copy Cell / Copy Row (full command included) / Copy PID
Settings Panel
- Refresh Interval — 1s / 2s / 5s / 10s
- Status Bar — Toggle visibility, position (left/right), priority, choose which metrics to display
- Disk Filter — Default / More / All / Custom (exclude FS types, path prefixes, virtual FS)
- Display — Enable/disable sparkline charts, chart duration (1–30 min)
Quick Start
- Install the extension from Marketplace or Open VSX
- Open a Linux workspace — Remote-SSH, WSL, Dev Container, or a local Linux desktop
- The sidebar icon and status bar metrics appear automatically
Note: The system must be Linux. On remote connections (SSH / WSL / Dev Container), the extension runs in the remote extension host. On local Linux, it reads system info directly. On non-Linux local machines, the extension offers to add itself to remote.SSH.defaultExtensions for auto-install on remote servers.
First launch
- Remote-SSH / local non-Linux: The extension offers to add itself to
remote.SSH.defaultExtensions so it auto-installs on every server you connect to.
- Local Linux: The extension activates immediately and monitors the local system.
Configuration
All settings are accessible via the Settings button in the sidebar panel. You can also edit settings.json directly:
{
"sysmonitor.refreshInterval": 2,
"sysmonitor.statusBar": {
"barEnabled": true,
"alignment": "left",

"skipIdle": false
}
},
"sysmonitor.disk": {

"hideParentMounts": true
}
}
