- Changed primary method to: ip -4 addr show scope global (gets public/private IPs only)
- Added isLoopbackIp() helper to filter out loopback addresses (127.* and ::1)
- Fallback: hostname -I with loopback filtering
- Last resort: gethostbyname() with loopback check
- On remote server with eth0: 159.89.175.190, will now show public IP instead of 127.0.0.1
Three-level fallback chain:
1. gethostbyname(gethostname()) - PHP built-in, works on Linux and Windows
2. ip -4 addr show scope global | grep inet - Linux shell fallback
3. hostname -I - Linux shell secondary fallback
All results validated with FILTER_VALIDATE_IP before display.
Update improvements:
- Renamed button from "Update System" to "Update HMS"
- Changed update to run only 'git pull' (removed database migrations)
- Added 60-second timeout to prevent system hangup
- Better error messages for timeouts and failures
- Logs update status (running/success/failed/timeout) to history
- Confirmation dialog now says "Pull latest HMS code from repository?"
This ensures quick updates without long-running migrations that could hang
the admin interface. Database migrations can be run separately as needed.
Resource Usage improvements:
- Added visual progress bars for CPU, RAM, and Disk usage
- Progress bars use Bootstrap styling (success/info/warning colors)
- Display percentage and detailed metrics (e.g., RAM 4 / 128 MB (3%))
- Bars animate smoothly with CSS transitions
CPU detection enhancements:
- Added fallback to /proc/stat parsing when shell commands unavailable
- Added fallback to PHP getrusage() for CPU time estimation
- CPU now displays even when shell_exec is disabled
- Graceful fallback chain ensures data is always available
Progress bar styling:
- Success (green) for CPU
- Info (blue) for RAM
- Warning (orange/yellow) for Disk
- All bars styled with height, rounded corners, and smooth transitions
When shell_exec() is disabled on the server (common in production), the system
operations panel now gracefully falls back to PHP built-in functions:
- gethostname() for hostname instead of shell 'hostname' command
- php_uname() for OS info instead of shell 'uname -a' command
- /proc/uptime parsing or unavailable status for uptime
- disk_free_space() and disk_total_space() for disk usage
- memory_get_usage() and PHP memory limit for memory usage
- Improved parsePhpMemoryLimit() to handle memory limit parsing
This ensures the admin panel shows meaningful information even in restricted
production environments where shell_exec is disabled for security reasons.
- Added System Operations link to Admin dashboard (app/Views/Setting/Admin/index.php)
- Uses load_form_div to load the system operations page inline
- Added SystemOperations library for server status collection and actions
- Tile uses server icon (bi-server) and appears in the admin panel grid
- Link: javascript:load_form_div(base_url('setting/admin/system-ops'), 'maindiv', 'System Operations')
