# Nerd Monitor - Quick Start Guide
|
|
|
|
## Building
|
|
|
|
```bash
|
|
# Build for current OS
|
|
make build
|
|
|
|
# Build for all platforms (Linux, macOS, Windows)
|
|
make build-all
|
|
|
|
# Clean build artifacts
|
|
make clean
|
|
```
|
|
|
|
## Running the Server
|
|
|
|
```bash
|
|
# Start server with default credentials (admin/admin)
|
|
./bin/nerd-monitor-server
|
|
|
|
# Start server on custom address/port
|
|
./bin/nerd-monitor-server -addr 0.0.0.0 -port 8080 -username myuser -password mypass
|
|
|
|
# Access the dashboard at: http://localhost:8080
|
|
```
|
|
|
|
## Running Agents
|
|
|
|
### Linux / macOS
|
|
```bash
|
|
# Default: connects to localhost:8080 every 15 seconds
|
|
./bin/nerd-monitor-agent
|
|
|
|
# Custom server
|
|
./bin/nerd-monitor-agent --server 10.0.20.80
|
|
|
|
# Custom server with port
|
|
./bin/nerd-monitor-agent --server 10.0.20.80:9090
|
|
|
|
# Custom reporting interval
|
|
./bin/nerd-monitor-agent --server myserver --interval 30s
|
|
```
|
|
|
|
### Windows
|
|
|
|
On Windows, use the batch wrapper to run the agent in the background (it won't show a terminal window):
|
|
|
|
```batch
|
|
# Default: connects to localhost:8080 every 15 seconds
|
|
nerd-monitor-agent.bat
|
|
|
|
# Custom server
|
|
nerd-monitor-agent.bat --server 10.0.20.80
|
|
|
|
# Custom server with port
|
|
nerd-monitor-agent.bat --server 10.0.20.80:9090
|
|
|
|
# Custom interval
|
|
nerd-monitor-agent.bat --server myserver --interval 30s
|
|
```
|
|
|
|
**Note**: The batch file automatically hides the console window and runs the agent as a background process.
|
|
|
|
## Dashboard Features
|
|
|
|
### Agent Status Indicators
|
|
- **Green "Online"** - Agent reported stats within the last 2 minutes
|
|
- **Red "Offline"** - Agent hasn't reported for more than 2 minutes
|
|
|
|
### Dashboard Overview
|
|
- Real-time agent status with online/offline indicators
|
|
- CPU usage percentage
|
|
- Memory (RAM) usage and total
|
|
- Disk usage and total
|
|
- Last seen timestamp
|
|
- All values are human-readable (B, KB, MB, GB, TB)
|
|
|
|
### Agent Detail Page
|
|
Click on any hostname to see detailed stats for that agent:
|
|
- CPU usage with progress bar
|
|
- Memory usage with progress bar
|
|
- Disk usage with progress bar
|
|
- Agent ID and detailed information
|
|
|
|
### Stale Agent Management
|
|
Agents that haven't reported for 6+ months show a warning. You can:
|
|
- See a list of all stale agents
|
|
- Bulk select and remove them
|
|
- Keep your dashboard clean
|
|
|
|
## Auto-Generation Features
|
|
|
|
### Agent ID
|
|
Agent IDs are automatically generated from the machine hostname (e.g., `my-laptop` or `DLO-DEV-001`)
|
|
|
|
### Auto-Refresh Dashboard
|
|
The dashboard automatically refreshes every 10 seconds to show the latest stats
|
|
|
|
## Connection Recovery
|
|
|
|
The agent automatically retries connections if the server is unavailable. It will keep attempting to report stats at the configured interval.
|
|
|
|
## Default Credentials
|
|
|
|
- **Username**: admin
|
|
- **Password**: admin
|
|
|
|
Change these when starting the server:
|
|
```bash
|
|
./bin/nerd-monitor-server -username myuser -password mysecurepass
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- **Server**: Web UI, API endpoint for agent stats, in-memory storage
|
|
- **Agent**: Lightweight monitoring agent that reports CPU, RAM, and Disk usage
|
|
- **No Database**: All data stored in server memory (resets on restart)
|
|
- **Minimal Dependencies**: Only Chi (router) and Templ (templating) besides Go stdlib
|
|
|
|
## Troubleshooting
|
|
|
|
### Agent shows "Offline" in dashboard
|
|
- Check if the agent process is running
|
|
- Verify the server address is correct
|
|
- Check network connectivity between agent and server
|
|
- Review agent logs for connection errors
|
|
|
|
### Windows agent terminal window appears then closes
|
|
- Use the `nerd-monitor-agent.bat` wrapper instead of the `.exe` directly
|
|
- The batch file handles running the agent in the background
|
|
|
|
### Can't connect to server
|
|
- Verify server is running: `http://localhost:8080`
|
|
- Check firewall rules allow the agent port
|
|
- Ensure correct server address and port are specified
