Moba Status Bar
A lightweight VS Code status bar resource monitor inspired by MobaXterm.
Moba Status Bar keeps CPU, memory, and disk usage visible in the VS Code status bar, so you can notice resource pressure without leaving your editor.

Features
- CPU usage in the status bar: shows current system CPU usage with a compact rectangular trend graph.
- Memory usage in the status bar: shows used memory and total memory, for example
8.4GB / 16.0GB.
- Workspace disk usage: shows usage for the disk that contains your first workspace folder. If no workspace is open, it uses your home directory.
- Top CPU processes: click the CPU item or run the command to see the top 5 CPU-consuming processes.
- Top memory processes: click the memory item or run the command to see the top 5 memory-consuming processes.
- Warning highlights: CPU, memory, and disk items can highlight automatically when usage reaches your configured threshold.
- Configurable refresh rate: choose how often CPU and memory usage updates.
Status Bar Items
After installation, the extension starts automatically when VS Code finishes launching.

Settings
You can configure Moba Status Bar from VS Code settings.
| Setting |
Default |
Description |
mobaStatusBar.enabled |
true |
Enable or disable the status bar monitor. |
mobaStatusBar.refreshIntervalMs |
1000 |
Enabled monitor refresh interval in milliseconds. Values below 500 are clamped to 500. |
mobaStatusBar.cpuEnabled |
true |
Enable CPU monitoring. When disabled, CPU sampling and CPU trend history are not collected. |
mobaStatusBar.cpuWarningThresholdPercent |
90 |
Highlight the CPU item when CPU usage is at or above this percentage. |
mobaStatusBar.showCpuTrendGraph |
true |
Show a compact CPU usage trend graph in the status bar. |
mobaStatusBar.cpuTrendGraphLength |
6 |
Number of samples shown in the CPU trend graph. |
mobaStatusBar.memoryEnabled |
true |
Enable memory monitoring. When disabled, memory usage is not sampled. |
mobaStatusBar.memoryWarningThresholdPercent |
90 |
Highlight the memory item when memory usage is at or above this percentage. |
mobaStatusBar.diskEnabled |
true |
Enable disk monitoring. When disabled, disk usage is not sampled. |
mobaStatusBar.diskWarningThresholdPercent |
85 |
Highlight the disk item when disk usage is at or above this percentage. |
Example settings.json:
{
"mobaStatusBar.refreshIntervalMs": 1500,
"mobaStatusBar.cpuEnabled": true,
"mobaStatusBar.cpuWarningThresholdPercent": 85,
"mobaStatusBar.showCpuTrendGraph": true,
"mobaStatusBar.cpuTrendGraphLength": 6,
"mobaStatusBar.memoryEnabled": true,
"mobaStatusBar.memoryWarningThresholdPercent": 90,
"mobaStatusBar.diskEnabled": true,
"mobaStatusBar.diskWarningThresholdPercent": 80
}
Notes
- Disk usage is cached and refreshed less often than CPU and memory to keep the extension lightweight.
- Disabled monitors are not sampled in the refresh loop.
- Process lists are collected only when you open them.
- On Windows, process data is collected through PowerShell/CIM. On macOS and Linux, it is collected through
ps.
