INSI YA KUTENGENEZA LOGS ZA ERRORS NA USER ACTIVITY (Logging Errors & Users)

Logging ni sehemu muhimu sana ya security, debugging, na system monitoring.
Kwa kuweka mfumo wa logs, unaweza kufuatilia makosa (errors), tabia za watumiaji (user activity), na kuboresha utendaji wa mfumo wako kwa muda mrefu.

🧠 1. KWA NINI LOGGING NI MUHIMU

Logging hukusaidia:

Kufahamu errors zinazotokea kwa muda halisi.

Kurekodi vitendo vya watumiaji kwa sababu za ufuatiliaji na usalama.

Kuboresha system reliability kwa kuchambua data ya matukio.

Kupunguza muda wa troubleshooting.

⚙️ 2. KUWEKA ERROR LOGGING YA PHP
a) Kuwezesha PHP Error Logging

Katika faili php.ini, hakikisha umeweka:

log_errors = On
error_log = /var/log/php_errors.log


Hii itahifadhi makosa yote ya PHP kwenye faili /var/log/php_errors.log.
Kwa Windows, unaweza kutumia path kama:

C:\xampp\php\logs\php_errors.log

b) Kurekodi Errors Kwenye File Fulani (kwa kila Project)
ini_set('log_errors', 1);
ini_set('error_log', __DIR__ . '/logs/error.log');
error_log("Error detected on: " . date('Y-m-d H:i:s'));


📎 Hapa tunatengeneza logs/ folder ndani ya project, na kuhifadhi makosa yote humo.

🧩 3. KUWEKA CUSTOM ERROR HANDLER

Unaweza kutumia set_error_handler() kurekodi makosa maalum.

function customErrorHandler($errno, $errstr, $errfile, $errline) {
$log = "[" . date('Y-m-d H:i:s') . "] Error: $errstr in $errfile on line $errline" . PHP_EOL;
file_put_contents(__DIR__ . '/logs/error.log', $log, FILE_APPEND);
}

set_error_handler("customErrorHandler");


➡️ Hii inahakikisha kila kosa linaingia kwenye error.log file na sio kuonekana kwa mtumiaji.

👥 4. KUREKODI USER ACTIVITY

Kwenye mifumo ya login au dashboard, unaweza kurekodi vitendo vya watumiaji (mfano: login, delete, upload, edit).

Mfano rahisi:

session_start();
$user = $_SESSION['username'] ?? 'Guest';
$action = "User $user uploaded a file";

$log = "[" . date('Y-m-d H:i:s') . "] $action" . PHP_EOL;
file_put_contents(__DIR__ . '/logs/user_activity.log', $log, FILE_APPEND);


💡 Hii ni muhimu kwa systems zenye users wengi kama admin dashboards au blog systems.

📋 5. KUHIFADHI LOGS KWENYE DATABASE

Unaweza pia kuhifadhi logs kwenye database kwa urahisi.

Mfano:

$stmt = $pdo->prepare("INSERT INTO activity_logs (username, action, timestamp) VALUES (?, ?, NOW())");
$stmt->execute([$user, $action]);


💡 Hii ni bora kama unataka kutengeneza “Activity History” au “Audit Trail” kwenye dashboard.

🧮 6. KUORGANIZE LOG FILES KWA UTAALAMU

Mfumo mzuri wa structure:

/project_root
├── logs/
│ ├── error.log
│ ├── access.log
│ ├── user_activity.log
│ └── security.log


error.log → PHP na system errors

access.log → Requests na IP addresses

user_activity.log → Matendo ya watumiaji

security.log → Vitendo visivyo salama au login failures

🛡️ 7. KUHAKIKISHA SECURITY YA LOGS

Weka logs/ folder nje ya public_html (ili zisipatikane moja kwa moja).

Weka .htaccess file kama:

Deny from all


Hakikisha logs haziwezi kufikiwa kupitia browser.

⚡ 8. KUONGEZA ALERT SYSTEM (EMAIL AU WHATSAPP)

Unaweza kutuma email notification kila error ikitokea:

$errorMessage = "Critical Error: $errstr in $errfile on line $errline";
mail("admin@faulink.com", "System Error", $errorMessage);

🧠 9. BEST PRACTICES

✅ Tenganisha error logs na user activity logs.
✅ Fanya rotation ya logs (zip old logs weekly).
✅ Usionyeshe errors moja kwa moja kwa watumiaji.
✅ Fanya backup ya logs mara kwa mara.
