otter-monitor is the Otter Shell system monitor. It runs as a normal Wayland window with live CPU, memory, GPU, disk, and network stats. Sort and search processes, group desktop apps, and end tasks from the table.

​
Usage

otter-monitor
Launch from otter-launcher or pin the Otter Monitor desktop entry. The sidebar lists eight views:
ViewWhat it shows
DashboardSummary cards and top resource consumers
ApplicationsDesktop apps grouped from .desktop entries
ProcessesFull process list with sortable columns
CPUPer-core usage and a 60-second history graph
MemoryRAM and swap usage with history
GPUDevice stats and per-process GPU or VRAM when NVML is available
DiskMount points, throughput, and I/O
NetworkInterfaces, throughput, and packet rates
Click a column header to sort. Filter by name in the search box. On Applications and Processes, the user filter shows only processes owned by your login.

​
Ending processes

Select a row and open the action menu. Quit sends SIGTERM. Force Quit sends SIGKILL. Either way, you confirm before the signal goes out.

​
Configuration

Config file: ~/.config/otter-shell/otter-monitor.conf 
refresh_interval_seconds = 3
  • refresh_interval_seconds: how often counters refresh (1 to 3600 seconds, default 3)
Edit the file in otter-settings on the Monitor tab, or by hand. Restart otter-monitor after changing the refresh interval. Colors come from theme.conf. otter-monitor watches that file and updates colors without a restart.

​
Dependencies

  • Wayland compositor with xdg_shell
  • Optional: NVIDIA driver with NVML for GPU process stats and VRAM columns
