What are best practices for implementing server monitoring in PHP, particularly in terms of database integration?

Implementing server monitoring in PHP involves regularly checking server metrics such as CPU usage, memory usage, disk space, and database performance. To integrate database monitoring, you can use PHP database functions to run queries that retrieve relevant metrics and store them in a monitoring database. This allows you to track the performance of your database over time and set up alerts for any anomalies. 

// Example PHP code snippet for database monitoring
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "monitoring_db";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Run query to retrieve database metrics
$sql = "SELECT * FROM database_metrics";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Metric: " . $row["metric_name"]. " - Value: " . $row["metric_value"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
