Are there any specific PHP functions or libraries that can help with monitoring server load?

Monitoring server load is crucial for maintaining the performance and stability of a web application. One way to achieve this is by using PHP functions or libraries that can help gather information about the server's current load, such as CPU usage, memory usage, and disk usage. By regularly monitoring these metrics, developers can identify potential bottlenecks and optimize their application accordingly. 

// Get CPU load
$cpu_load = sys_getloadavg()[0];

// Get memory usage
$mem_total = shell_exec("free -m | grep Mem | awk '{print $2}'");
$mem_used = shell_exec("free -m | grep Mem | awk '{print $3}'");
$mem_usage = round(($mem_used / $mem_total) * 100, 2);

// Get disk usage
$disk_total = disk_total_space("/");
$disk_free = disk_free_space("/");
$disk_usage = round((($disk_total - $disk_free) / $disk_total) * 100, 2);

// Display server load information
echo "CPU Load: " . $cpu_load . "\n";
echo "Memory Usage: " . $mem_usage . "%\n";
echo "Disk Usage: " . $disk_usage . "%\n";
