# Progress Tracking and System Status Enhancement Guide
|
|
|
|
This document describes the improvements made to the ZitiNexus Router Enrollment UI to fix progress tracking and system status checking issues.
|
|
|
|
## 🔧 Issues Fixed
|
|
|
|
### Issue 1: Progress UI Always Shows "Initializing"
|
|
**Problem**: The enrollment progress UI would always show "Initializing" throughout the entire enrollment process, providing no real-time feedback to users.
|
|
|
|
**Root Cause**: The original implementation used a single synchronous AJAX call that waited for the entire enrollment to complete before returning results. No progress streaming mechanism existed.
|
|
|
|
**Solution**: Implemented real-time progress tracking using AJAX polling:
|
|
- Progress data is stored in PHP sessions during enrollment
|
|
- JavaScript polls a progress endpoint every 500ms
|
|
- UI updates in real-time showing current step, percentage, and logs
|
|
|
|
### Issue 2: System Status Not Actively Checking After Enrollment
|
|
**Problem**: System status would show outdated information, especially after package removal/purge operations. The status checking was not thorough enough.
|
|
|
|
**Root Cause**:
|
|
- Status checking only verified if commands existed, not if packages were properly installed
|
|
- No real-time verification of package installation status
|
|
- Cache issues prevented fresh status checks
|
|
|
|
**Solution**: Enhanced system status checking:
|
|
- Added package detection via `dpkg` commands
|
|
- Implemented real-time status refresh functionality
|
|
- Better certificate checking using sudo for root-owned files
|
|
- Force refresh capabilities to clear caches
|
|
|
|
## 🚀 New Features
|
|
|
|
### Real-Time Progress Tracking
|
|
|
|
#### Files Added/Modified:
|
|
- `UI/progress.php` - Progress polling endpoint
|
|
- `UI/public/progress.php` - Public directory version
|
|
- `UI/includes/enrollment.php` - Enhanced with session-based progress tracking
|
|
- `UI/public/assets/js/app.js` - Added AJAX polling functionality
|
|
- `UI/dashboard.php` - Added progress management endpoints
|
|
|
|
#### How It Works:
|
|
1. **Enrollment Start**: Progress is initialized in PHP session
|
|
2. **Progress Updates**: Each enrollment step updates session data
|
|
3. **AJAX Polling**: JavaScript polls progress endpoint every 500ms
|
|
4. **UI Updates**: Progress bar, steps, and logs update in real-time
|
|
5. **Completion**: Polling stops when enrollment completes or fails
|
|
|
|
#### Progress Data Structure:
|
|
```php
|
|
$_SESSION['enrollment_progress'] = [
|
|
'step' => 'CURRENT_STEP', // Current step name
|
|
'message' => 'Step description', // Current step message
|
|
'percentage' => 50, // Progress percentage (0-100)
|
|
'completed_steps' => ['INIT', ...], // Array of completed steps
|
|
'current_step_index' => 4, // Current step index
|
|
'status' => 'running', // ready, running, completed, error
|
|
'error' => null, // Error message if failed
|
|
'logs' => [ // Array of log entries
|
|
[
|
|
'timestamp' => '12:34:56',
|
|
'step' => 'INSTALL',
|
|
'message' => 'Installing...',
|
|
'type' => 'info'
|
|
]
|
|
]
|
|
];
|
|
```
|
|
|
|
### Enhanced System Status Checking
|
|
|
|
#### New Methods Added:
|
|
- `checkZitiInstallation()` - Comprehensive package and command checking
|
|
- `checkServiceStatus()` - Thorough service status verification
|
|
- `checkCertificatesExist()` - Sudo-based certificate checking
|
|
- `refreshSystemStatus()` - Force refresh with cache clearing
|
|
|
|
#### Enhanced Status Data:
|
|
```php
|
|
$status = [
|
|
'hostname' => 'server-name',
|
|
'ziti_status' => 'installed', // installed, not_installed, broken
|
|
'ziti_version' => 'v1.5.4',
|
|
'service_active' => true,
|
|
'config_exists' => true,
|
|
'certificates_exist' => true,
|
|
'package_installed' => true, // NEW: dpkg package check
|
|
'last_checked' => 1640995200 // NEW: timestamp
|
|
];
|
|
```
|
|
|
|
## 📋 API Endpoints
|
|
|
|
### Progress Tracking
|
|
- `GET /progress.php` - Get current enrollment progress
|
|
- `GET /dashboard.php?action=clear_progress` - Clear progress data
|
|
|
|
### System Status
|
|
- `GET /dashboard.php?action=get_status` - Get current system status
|
|
- `GET /dashboard.php?action=refresh_status` - Force refresh system status
|
|
|
|
## 🎯 User Experience Improvements

|
## 🔍 Technical Implementation Details
|
|
|
|
### Progress Polling Architecture:
|
|
```
|
|
User clicks "Start Enrollment"
|
|
↓
|
|
JavaScript starts AJAX polling (500ms interval)
|
|
↓
|
|
PHP enrollment process updates session progress
|
|
↓
|
|
JavaScript fetches progress and updates UI
|
|
↓
|
|
Process continues until completion/error
|
|
↓
|
|
Polling stops automatically
|
|
```
|
|
|
|
### System Status Enhancement:
|
|
```
|
|
User clicks "Refresh Status"
|
|
↓
|
|
JavaScript calls refresh_status endpoint
|
|
↓
|
|
PHP clears caches and runs comprehensive checks
|
|
↓
|
|
Enhanced status data returned to UI
|
|
↓
|
|
UI updates with fresh system information
|
|
```
|
|
|
|
## 🛠️ Maintenance Notes
|
|
|
|
### Session Management:
|
|
- Progress data is automatically cleaned up after completion
|
|
- Session data is limited to last 50 log entries to prevent memory issues
|
|
- Progress can be manually cleared via API endpoint
|
|
|
|
### Performance Considerations:
|
|
- Polling interval is 500ms (configurable)
|
|
- Polling automatically stops when not needed
|
|
- System status auto-refreshes every 30 seconds (when not enrolling)
|
|
|
|
### Error Handling:
|
|
- Progress polling continues even if individual requests fail
|
|
- System status gracefully handles command failures
|
|
- User feedback provided for all error conditions
|
|
|
|
## 🔧 Configuration Options
|
|
|
|
### JavaScript Polling Interval:
|
|
```javascript
|
|
// In app.js, modify this value to change polling frequency
|
|
this.progressPollingInterval = setInterval(async () => {
|
|
// ... polling logic
|
|
}, 500); // 500ms = 0.5 seconds
|
|
```
|
|
|
|
### Session Progress Cleanup:
|
|
```php
|
|
// In enrollment.php, modify log retention
|
|
if (count($progress['logs']) > 50) {
|
|
$progress['logs'] = array_slice($progress['logs'], -50);
|
|
}
|
|
```
|
|
|
|
## 🎉 Benefits
|
|
|
|
1. **Better User Experience**: Users now see real-time progress instead of waiting blindly
|
|
2. **Accurate System Status**: Enhanced checking provides reliable system state information
|
|
3. **Improved Debugging**: Live logs help identify issues during enrollment
|
|
4. **Professional Feel**: Progress indicators make the system feel more responsive
|
|
5. **Reliability**: Better error handling and status verification improve overall reliability
|
|
|
|
This enhancement transforms the enrollment experience from a "black box" operation to a transparent, user-friendly process with real-time feedback and accurate system monitoring.
