Logger for Aws Cloud Watch

Breaking Change for version 1.0

When this package started, it started as a listener for log events and would only work with another channel. This package would listen to log events and just add extra log to cloud watch. So, you did not need to add cloudwatch as a channel. But after 1.0 it works as a custom driver. So, you MUST add LOG_CHANNEL as cloudwatch in your logging config for this to work going forward.

Installation

composer require pagevamp/laravel-cloudwatch-logs

Example

You can use laravel's default \Log class to use this

\Log::info('user logged in', ['id' => 123, 'name' => 'Naren']);

Usage with AWS Lambda

Make sure the AWS Lambda template contains an IAM role with enough access. So think about Logs:CreateLogGroup, Logs:DescribeLogGroups, Logs:CreateLogStream, Logs:DescribeLogStream, Logs:PutRetentionPolicy and Logs:PutLogEvents

Config

Config for logging is defined at config/logging.php. Add cloudwatch to the channels array

'channels' =>  [
    'cloudwatch' => [
            'driver' => 'custom',
            'name' => env('CLOUDWATCH_LOG_NAME', ''),
            'region' => env('CLOUDWATCH_LOG_REGION', ''),
            'credentials' => [
                'key' => env('CLOUDWATCH_LOG_KEY', ''),
                'secret' => env('CLOUDWATCH_LOG_SECRET', '')
            ],
            'stream_name' => env('CLOUDWATCH_LOG_STREAM_NAME', 'laravel_app'),
            'retention' => env('CLOUDWATCH_LOG_RETENTION_DAYS', 14),
            'group_name' => env('CLOUDWATCH_LOG_GROUP_NAME', 'laravel_app'),
            'version' => env('CLOUDWATCH_LOG_VERSION', 'latest'),
            'formatter' => \Monolog\Formatter\JsonFormatter::class,       
            'batch_size' => env('CLOUDWATCH_LOG_BATCH_SIZE', 10000),    
            'via' => \Pagevamp\Logger::class,
        ],
]

And set the LOG_CHANNEL in your environment variable to cloudwatch.

If the role of your AWS EC2 instance has access to Cloudwatch logs, CLOUDWATCH_LOG_KEY and CLOUDWATCH_LOG_SECRET need not be defined in your .env file.
