So now we have the place holder for the Google Chart scripts .
8. Create the needed scripts ( working example below ) and transfer them to the iBay created above :
Script to monitor http memory usage (mysqli_apache_memory_used.php ) :
<?php
// Hostname: 127.0.0.1, username: your_user, password: your_pass, db: your_db
$mysqli = new mysqli('localhost', 'username', 'password', 'db_name');
// Oh no! A connect_errno exists so the connection attempt failed!
if ($mysqli->connect_errno) {
// The connection failed. What do you want to do?
// You could contact yourself (email?), log the error, show a nice page, etc.
// You do not want to reveal sensitive information
// Let's try this:
echo "Sorry, this website is experiencing problems.";
// Something you should not do on a public site, but this example will show you
// anyways, is print out MySQL error related information -- you might log this
echo "Error: Failed to make a MySQL connection, here is why: \n";
echo "Errno: " . $mysqli->connect_errno . "\n";
echo "Error: " . $mysqli->connect_error . "\n";
// You might want to show them something nice, but we will simply exit
exit;
}
// Perform an SQL query
//$query = "SELECT number, period, process_size, processors_used FROM performance LIMIT 50";
$query ="SELECT number, period, process_size, processors_used, mem_used FROM performance WHERE period > DATE_SUB(NOW(), INTERVAL 48 HOUR)";
if (!$result = $mysqli->query($query)) {
// Oh no! The query failed.
echo "Sorry, the website is experiencing problems.";
// Again, do not do this on a public site, but we'll show you how
// to get the error information
echo "Error: Our query failed to execute and here is why: \n";
echo "Query: " . $sql . "\n";
echo "Errno: " . $mysqli->errno . "\n";
echo "Error: " . $mysqli->error . "\n";
exit;
}
// Phew, we made it. We know our MySQL connection and query
// succeeded, but do we have a result?
if ($result->num_rows === 0) {
// Oh, no rows! Sometimes that's expected and okay, sometimes
// it is not. You decide. In this case, maybe actor_id was too
// large?
echo "We could not find a match , sorry about that. Please try again.";
exit;
}
$qresult = $mysqli->query($query);
$results = array();
while($res = $qresult->fetch_assoc()) {
$results[] = $res;
}
$curvechart_data = array();
foreach($results as $result)
{
//$curvechart_data[] = array($result['period'],(int)$result['process_size'], (int)$result['processors_used'],(int)$result['mem_used']);
$curvechart_data[] = array($result['period'],(int)$result['mem_used']);
}
$curvechart_data = json_encode($curvechart_data);
//echo $curvechart_data;
// The script will automatically free the result and close the MySQL
// connection when it exits, but let's just do it anyways
//$result->free();
//$mysqli->close();
