System Monitor
Dinotty has a built-in system monitor showing real-time CPU, memory, and network metrics for the server. No need to install htop or Activity Monitor separately.
Opening the Monitor
| Method | Action |
|---|---|
| Terminal toolbar | Click the "Monitor" icon in the pane title bar |
| Command Palette | Type monitor.open |
| Settings -> Monitor | View long-history data |
Monitor data comes from the server, reflecting the server host's load, not the client's.
Real-time Metrics
| Metric | Description |
|---|---|
| CPU | Overall usage percentage + per-core line chart |
| Memory | Used / total / swap |
| Network | Inbound / outbound throughput (KB/s) |
| Process count | Total server process count |
Refresh defaults to once per second. Adjust the interval in settings (1s / 2s / 5s).
Historical Data
Below the real-time stats is a 60-second line chart:
- CPU line (red)
- Memory line (green)
- Network line (blue)
Hover for exact values. History is in-memory only, cleared on server restart.
Monitor Popover
The MonitorPopover at the top of the terminal pane is a lightweight popup:
- Click the "Monitor" icon to pop
- Does not switch panes, overlays the current pane
- Shows the current pane's usage (PTY output volume, child process CPU / memory)
Useful for diagnosing whether an agent is stuck or consuming too much.
Typical Use Cases
Diagnosing a stuck agent
Agent stops responding:
- Open that pane's MonitorPopover
- Check if PTY output volume is still growing
- Check if child process CPU is at zero (agent exited / waiting for input)
- Check if child process memory is spiking (pre-OOM)
Server load monitoring
For a VPS-deployed server:
- Open Dinotty remotely
- Settings -> Monitor for long-history view
- Spot sustained 90%+ CPU, locate the offending process
Multi-device shared monitoring
The server has a single source of monitor data; all connected devices see the same view. Mobile can also check server load.
Notification Integration
Configure threshold alerts in settings:
- CPU > 80% for 30s -> trigger notification
- Memory > 90% -> trigger notification
Notifications push to all devices via the Notification System.
