 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";

            $process->setCommandLine($manipulatedCommand);

            $process->setTimeout(60);
        }

        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.
