Manipulating processes

Under the hood Symfony\Component\Process is used to connect to your server and performing the command from your check. You can manipulate this Process right before it is executed.

To do this you must create a class that implements Spatie\ServerMonitor\Manipulators\Manipulator. That interface has only a single method to implement:

public function manipulateProcess(Process $process, Check $check): Process;

Let's take a look at an example implementation. In the code below we're going to change the command and up the timeout if the check is being performed on a certain host.

namespace App\ServerMonitor\Manipulators;

use Spatie\ServerMonitor\Models\Check;
use Symfony\Component\Process\Process;

class MyManipulator implements Manipulator
    public function manipulateProcess(Process $process, Check $check): Process
        if ($check->host->name = 'my-host') {
            $manipulatedCommand = "{$process->getCommandLine()} appending extra options";
        return $process;

After creating the class you must specify it's fully qualified name in the process_manipulator key of the server-monitor config file.
