Inspector for PHP applications.


Total Downloads Latest Stable Version License Contributor Covenant Build Status

Simple code execution monitoring, built for PHP developers.


  • PHP >= 7.2.0


Install the latest version by:

composer require inspector-apm/inspector-php


To start sending data to Inspector you need an Ingestion Key to create an instance of the Configuration class. You can obtain INSPECTOR_API_KEY creating a new project in your Inspector dashboard.

use Inspector\Inspector;
use Inspector\Configuration;

$configuration = new Configuration('YOUR_INGESTION_KEY');
$inspector = new Inspector($configuration);

All start with a transaction. Transaction represent an execution cycle and it can contains one or hundred of segments:

// Start an execution cycle with a transaction

Use addSegment method to monitor a code block in your transaction:

$result = $inspector->addSegment(function ($segment) {
    // Do something here...
	return "Hello World!";
}, 'my-process');

echo $result; // this will print "Hello World!"

Inspector will monitor your code execution in real time alerting you if something goes wrong.

Custom Transport

You can also set up custom transport class to transfer monitoring data from your server to Inspector in a personalized way.

The transport class needs to implement \Inspector\Transports\TransportInterface:

class CustomTransport implements \Inspector\Transports\TransportInterface
    protected $configuration;

    protected $queue = [];

    public function __constructor($configuration)
        $this->configuration = $configuration;

    public function addEntry(\Inspector\Models\Arrayable $entry)
        // Add an \Inspector\Models\Arrayable entry in the queue.
        $this->queue[] = $entry;

    public function flush()
        // Performs data transfer.
        $handle = curl_init('');
        curl_setopt($handle, CURLOPT_POST, 1);
        curl_setopt($handle, CURLOPT_HTTPHEADER, [
            'X-Inspector-Key: xxxxxxxxxxxx',
            'Content-Type: application/json',
            'Accept: application/json',
        curl_setopt($handle, CURLOPT_POSTFIELDS, json_encode($this->queue));

Then you can set the new transport in the Inspector instance using a callback the will receive the current configuration state as parameter.

$inspector->setTransport(function ($configuration) {
    return new CustomTransport($configuration);
