Gateway Overview
The Gateway Overview page displays the gateway's running status, system resource usage, and project configuration information in real time. It is the core entry point for daily operations and maintenance monitoring. Page data refreshes automatically every 3 seconds.
Page Entry
After logging into the system, the Gateway Overview page is displayed by default, or you can click "Gateway Overview" in the left menu to enter.
Statistics Cards
| Card | Description |
|---|---|
| Total Channels | Displays total number of channels, enabled count, disabled count |
| Total Devices | Displays total number of devices, online count, offline count |
| Total Variables | Displays total number of variables, normal count, abnormal count |
| Real-time Alarms | Displays real-time alarm count, alarm count, recovery count |
System Resource Monitoring
| Metric | Description |
|---|---|
| CPU Usage | System CPU usage percentage, with progress bar. Normal: <60%; Warning: 60-80%; Critical: >80% |
| Memory Usage | System memory usage percentage, showing used/total |
| Process Memory | Current process memory usage, showing GC memory value and thread count (format: GC: xxx MB | Threads: N). Continuous growth of GC memory may indicate a memory leak |
| Disk Usage | System disk usage percentage, showing used/total. Insufficient disk space affects data storage and log recording |
| System Uptime | Running time since system startup |
Performance Monitoring Recommendations
- When CPU consistently exceeds 80%, check if there is a large amount of concurrent device collection or complex rule engine calculations
- When memory continues to grow without dropping, it may be a memory leak; it is recommended to restart the runtime service
- It is normal for GC memory to be much smaller than process memory; the .NET runtime pre-allocates memory
CPU Trend Chart
Displays the historical trend curve of CPU usage, refreshing data every 3 seconds.
Network Speed Chart
Displays the historical trend curve of network upload and download speeds.
Project Information
Displays basic information about the current project, using a responsive layout:
| Information | Description |
|---|---|
| Firmware Version | Gateway firmware version number |
| Serial Number | Device serial number/UUID |
| AOT Publish | Whether it is an AOT publish version. AOT (Ahead-of-Time) pre-compiled publish, can run without installing .NET runtime, starts faster but has a larger size |
| Max Authorized Channels | Number of channels authorized. When exceeded, new channels cannot be added; please contact the supplier to upgrade the authorization |
| Max Authorized Devices | Number of devices authorized. When exceeded, new devices cannot be added; please contact the supplier to upgrade the authorization |
| Max Authorized Variables | Number of variables authorized. When exceeded, new variables cannot be added; please contact the supplier to upgrade the authorization |
| Project Name | Name of the currently loaded project |
| Project Description | Project description information |
| Project Version | Project version number |
| Project Generation Time | Time when the project was generated |
