Mezmo/LogDNA handler for Monolog

Monolog backend for mezmo/logdna. This backend use mezmo/logdna ingestion api.

Install

Install with compose composer require nvanheuverzwijn/monolog-logdna.

Usage

$logger = new \Monolog\Logger('general');
$logdnaHandler = new \Zwijn\Monolog\Handler\LogdnaHandler('your-key', 'myappname', \Monolog\Logger::DEBUG);
$logger->pushHandler($logdnaHandler); 

# Sends debug level message "mylog" with some related meta-data
$logger->debug(
  "mylog",
  [
    'logdna-meta-data-field1' => ['value1' => 'value', 'value2' => 5],
    'logdna-meta-data-field2' => ['value1' => 'value']
  ]
);

Live Example

Create the following php script test.php. Don't forget to set the ingestion key prior to running this script.

<?php

include './vendor/autoload.php';

$INGESTION_KEY='';
\date_default_timezone_set('America/Montreal');

$logger = new \Monolog\Logger('general');
$logdnaHandler = new \Zwijn\Monolog\Handler\LogdnaHandler($INGESTION_KEY, 'appname', \Monolog\Logger::DEBUG);
$logger->pushHandler($logdnaHandler);
$logger->debug('mylog');

Execute it with the following docker command.

docker run -it --rm -v "${PWD}":/usr/src/myapp -w /usr/src/myapp php:8-cli php test.php

You should see the log 'mylog' with debug level in the mezmo/logdna account for which the ingestion key is bound to.

Using with Monolog Processors

Monolog Processors may add some extra data to the log records. This data will appear in logdna log metadata as property monolog_extra unless it is empty. If such a property already exists in the log record's context, it will be overwritten.

Time Drift Calculation

By default, the handler sends now parameter to the Ingestion API, which is used to calculate time drift. You can disable sending this parameter via

$logdnaHandler->setIncludeRequestTime(false);
