Installation

Install the latest version with composer require stackify/monolog "~2.0"

Installation with Linux Agent

This is the suggested installation option, offering the best logging performance.

PHP:

use Monolog\Logger;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$handler = new StackifyHandler('application_name', 'environment_name');
$logger = new Logger('logger');
$logger->pushHandler($handler);

Symfony:

services:
    stackify_handler:
        class: "Stackify\\Log\\Monolog\\Handler"
        arguments: ["application_name", "environment_name"]
monolog:
    handlers:
        stackify:
            type: service
            id: stackify_handler

Optional Settings

Log Server Environment Variables

• Server environment variables can be added to error log message metadata. Note: This will log all system environment variables; do not enable if sensitive information such as passwords or keys are stored this way.

$handler = new StackifyHandler('application_name', 'environment_name', null, true); 

Installation without Linux Agent

This option does not require a Stackify Agent to be installed because it sends data directly to Stackify services. It collects log entries in batches, calls curl using the exec function, and sends data to the background immediately [exec('curl ... &')]. This will affect the performance of your application minimally, but it requires permissions to call exec inside the PHP script and it may cause silent data loss in the event of any network issues. This transport method does not work on Windows. To configure ExecTransport you need to pass the environment name and API key (license key):

PHP:

use Stackify\Log\Transport\ExecTransport;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$transport = new ExecTransport('api_key');
$handler = new StackifyHandler('application_name', 'environment_name', $transport);
$logger = new Logger('logger');
$logger->pushHandler($handler);

Symfony:

services:
    stackify_transport:
        class: "Stackify\\Log\\Transport\ExecTransport"
        arguments: ["api_key"]
    stackify_handler:
        class: "Stackify\\Log\\Monolog\\Handler"
        arguments: ["application_name", "environment_name", "@stackify_transport"]
monolog:
    handlers:
        stackify:
            type: service
            id: stackify_handler

Optional Configuration

Proxy

• ExecTransport supports data delivery through proxy. Specify proxy using libcurl format: <[protocol://][user:password@]proxyhost[:port]>

$transport = new ExecTransport($apiKey, ['proxy' => 'https://55.88.22.11:3128']);

Curl path

• It can be useful to specify curl destination path for ExecTransport. This option is set to 'curl' by default.

$transport = new ExecTransport($apiKey, ['curlPath' => '/usr/bin/curl']);

Log Server Environment Variables

• Server environment variables can be added to error log message metadata. Note: This will log all system environment variables; do not enable if sensitive information such as passwords or keys are stored this way.

$handler = new StackifyHandler('application_name', 'environment_name', $transport, true); 

Notes

To get more error details pass Exception objects to the logger if available:

try {
    $db->connect();
catch (DbException $ex) {
    // you may use any key name
    $logger->addError('DB is not available', ['ex' => $ex]);
}

Additional Configuration

For additional configurations, you can set on the XML or the PHP File Configuration. Reference for the additional options are located on the stackify logger repository Stackify PHP Logger - Configuration Settings

Transport Level

• This applies to all the transports (ExecTransport, CurlTransport, AgentTransport, AgentSocketTransport)

use Monolog\Logger;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$config = array(
       'CaptureServerVariables' => false,
       'CaptureServerVariablesWhitelist' => '*',
       'CaptureServerVariablesBlacklist' => 'REMOTE_ADDR,SERVER_ADDR',
       ...
   );

$transport = new ExecTransport($apiKey, [
   'config' => $config
]);

$handler = new StackifyHandler('application_name', 'environment_name', $transport);
$logger = new Logger('logger');
$logger->pushHandler($handler);

Handler Level

• This applies to the current Monolog Handler

use Monolog\Logger;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$transport = new ExecTransport($apiKey); // Your selected transport (Can be null which defaults to AgentSocketTransport)
$logServerVariables = false; // Default
$config = array(
       'CaptureServerVariables' => false,
       'CaptureServerVariablesWhitelist' => '*',
       'CaptureServerVariablesBlacklist' => 'REMOTE_ADDR,SERVER_ADDR',
       ...
);

$handler = new StackifyHandler('application_name', 'environment_name', $transport, $logServerVariables, $config);
$logger = new Logger('logger');
$logger->pushHandler($handler);

Handler Level Option

• Include Channel
  • This will include the logger name or the channel set for the log entry.

use Monolog\Logger;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$transport = new ExecTransport($apiKey); // Your selected transport (Can be null which defaults to AgentSocketTransport)
$logServerVariables = false; // Default
$config = array(
       'IncludeChannel' => true,
       ...
);

$handler = new StackifyHandler('application_name', 'environment_name', $transport, $logServerVariables, $config);
$logger = new Logger('logger');
$logger->pushHandler($handler);

• Include Extra In Context
  • This will include the extra property to the context (merging extra to context)

use Monolog\Logger;
use Stackify\Log\Monolog\Handler as StackifyHandler;

$transport = new ExecTransport($apiKey); // Your selected transport (Can be null which defaults to AgentSocketTransport)
$logServerVariables = false; // Default
$config = array(
       'IncludeExtraInContext' => true,
       ...
);

$handler = new StackifyHandler('application_name', 'environment_name', $transport, $logServerVariables, $config);
$logger = new Logger('logger');
$logger->pushProcessor(function ($record) {
     if (empty($record['extra'])) {
       $record['extra'] = [];
     }
     $record['extra']['dummy'] = 1;
     return $record;
});
$logger->pushHandler($handler);

Symfony

services:
    stackify_transport:
        class: "Stackify\\Log\\Transport\\CurlTransport"
        arguments: ["api_key"]
# Square/Curly Brackets
    stackify_handler:
        class: "Stackify\\Log\\Monolog\\Handler"
        arguments: ["application_name", "environment_name", "@stackify_transport", false, { CaptureServerVariables: false, ... }]
# or
# Dash/Colon Space
    stackify_handler:
        class: "Stackify\\Log\\Monolog\\Handler"
        arguments:
            - "application_name"
            - "environment_name"
            - "@stackify_transport"
            - false
            - CaptureServerVariables: false
              CaptureServerWhitelist: "*"
              CaptureServerBlacklist: null
              
monolog:
    handlers:
        stackify:
            type: service
            id: stackify_handler

Troubleshooting

If transport does not work, try looking into vendor\stackify\logger\src\Stackify\debug\log.log file (if it is available for writing). Errors are also written to global PHP error_log. Note that ExecTransport does not produce any errors at all, but you can switch it to debug mode:

$transport = new ExecTransport($apiKey, ['debug' => true]);

You can set it also on the Logger level. Setting the Debug and DebugLogPath

$config = array(
        'DebugLogPath' => '/path/to/log.log',
        'Debug' => true
    );

$logger = new StackifyHandler('application_name', 'environment_name', $transport, $logServerVariables, $config);
