    }
...
}

Usage

Trigger an event

use \PagerDuty\TriggerEvent;
use \PagerDuty\Exceptions\PagerDutyException;

$routingKey = "1d334a4819fc4b67a795b1c54f9a"; //Replace this with the integration key of your service.

// In this example, we're triggering a "Service is down" message from a web server.
try {
    $event = new TriggerEvent(
        $routingKey, 
        "Service is down",  // A high-level, text summary message of the event. Will be used to construct an alert's description.
        "web-server-01",    // human-readable unique identifier, such as a hostname, for the system having the problem.
        TriggerEvent::ERROR,// How impacted the affected system is? Influences the priority of any created incidents. 
        true                // Generate the dedup_key from the driver. If false, the dedup_key will be generated on PD 
    );
    $responseCode = $event->send();
    if($responseCode == 200)
        echo "Success";
    elseif($responseCode == 429)
        echo "Rate Limited";  //You're being throttled. Slow down.
    else // An error occured. Try again later
        echo "Some error has occured. Try again later";
} catch(PagerDutyException $exception) { //This doesn't happen unless you've broken their guidelines. The API tries to minimize user mistakes
    var_dump($exception->getErrors());
}

Trigger event with custom connection, for example: using proxies and/or setting verbosity for debugging, etc.


use \PagerDuty\TriggerEvent;
use \PagerDuty\Exceptions\PagerDutyException;
use \PagerDuty\Http\PagerDutyHttpConnection;

try {
    $routingKey = '1d334a4819fc4b67a795b1c54f9a';  //Replace this with the integration key of your service.

    $event = new TriggerEvent(
        $routingKey, 
        "Service is down",  // A high-level, text summary message of the event. Will be used to construct an alert's description.
        "web-server-01",    // human-readable unique identifier, such as a hostname, for the system having the problem.
        TriggerEvent::ERROR,// How impacted the affected system is? Influences the priority of any created incidents. 
        true                // Generate the dedup_key from the driver. If false, the dedup_key will be generated on PD 
    );

    // create a custom proxy connection
    $connection = new PagerDutyHttpConnection();

    // .. and set the proxy
    $connection->setProxy('https://user:password@your-proxy-ip-address:port');

    // set custom CURL options. Here we set verbosity for debugging
    $connection->addCurlOption('CURLOPT_VERBOSE', 1);
    
    // send event through proxy
    $connection->send($event);
}
catch(PagerDutyException $exception) { //This doesn't happen unless you've broken their guidelines. The API tries to minimize user mistakes
    var_dump($exception->getErrors());
}
catch (\Exception $e) {
    // A configuration exception
}

Automatically send only one PagerDuty incident for repeated errors


//You will only see one incident on PD
(TriggerEvent($routingKey, "Service is down", "web-server-01", TriggerEvent::ERROR, true))->send();
(TriggerEvent($routingKey, "Service is down", "web-server-01", TriggerEvent::ERROR, true))->send();
(TriggerEvent($routingKey, "Service is down", "web-server-01", TriggerEvent::ERROR, true))->send();

Create a detailed 'trigger' event, add optional data. Dump the event and inspect response from PD

use \PagerDuty\TriggerEvent;

//Taken from the `trigger` example @ https://v2.developer.pagerduty.com/docs/send-an-event-events-api-v2
//Send a detailed event, and store the `dedup_key` generated on the server

$event = new TriggerEvent(
    $routingKey, 
    "Example alert on host1.example.com", 
    "monitoringtool:cloudvendor:central-region-dc-01:852559987:cluster/api-stats-prod-003", 
    TriggerEvent::INFO
);
$event
    ->setPayloadTimestamp("2015-07-17T08:42:58.315+0000")
    ->setPayloadComponent("postgres")
    ->setPayloadGroup("prod-datapipe")
    ->setPayloadClass("deploy")
    ->setPayloadCustomDetails(["ping_time" => "1500ms", "load_avg" => 0.75])
    ->addLink("https://example.com/", "Link text")
    ->addImage("https://www.pagerduty.com/wp-content/uploads/2016/05/pagerduty-logo-green.png", "https://example.com/", "Example text"))
;

// Pass in the '$response' variable by reference if you want to inspect PD's response. This is optional, and you probably don't need this in production.
$response = null;
$responseCode = $event->send($response);
// In this case, we will save the `dedup_key` generated by the PD server
var_dump($response['dedup_key']);

Acknowledge an event

(new AcknowledgeEvent($routingKey, "dedup key"))->send();

Resolve an event

(new ResolveEvent($routingKey, "dedup key"))->send();

Questions

Q. How do i get the service key from PagerDuty?

A. In your PagerDuty console, click 'Configuration' > 'Services'. Click the link under 'Integrations' column. It's the 'Integration Key'
