Master	Development

Installing

DTail is available on Packagist.

To install with composer, add: "otternq/dtail": "dev-master" to composer.json in the require section:

"require": {
    "php": ">=5.3.3",
    "otternq/dtail": "dev-master"
}

then run php composer.phar update (or php composer.phar install depending on the situation) and let composer do the rest.

Usage

If you want to incoorperate this into another system, see Usage 1. If you just want to see the log entries, see Usage 2

###Usage 1

include "vendor/autoload.php";

use Colors\Color;

use Aws\Common\Aws;
use Aws\DynamoDb\DynamoDbClient;

use DTail\DTail;

$config = array(
    'dyn-table' => 'PHPErrors',
    'dyn-key'    => YOUR_AWS_KEY,
    'dyn-secret' => YOUR_AWS_SECRET,
    'dyn-region' => 'us-east-1'
);

$dynamodbClient = DynamoDbClient::factory(array(
    'key'    => $config['dyn-key'],
    'secret' => $config['dyn-secret'],
    'region' => $config['dyn-region'],
    )
);

$dtail = new DTail($dynamodbClient);

$iterator = $dtail->get(
    $config['dyn-table'], 
    'PHPErrorReporter'
);

foreach($iterator as $item) {
    var_dump($item);
}

###Usage 2

If you just want to watch/search log files then use the bin/dtail command:

bin/dtail -f /path/to/config/file.php

the config file will look like:

return array(
    'dyn-table' => 'PHPErrors',
    'dyn-key'    => YOUR_AWS_KEY,
    'dyn-secret' => YOUR_AWS_SECRET,
    'dyn-region' => 'us-east-1'
);

and the output will look like:
