A collection of Yii2 log targets that format the log message as a JSON string.

Usage

EmailServiceTarget

The EmailServiceTarget is used to send logs to our external Email Service API

Note, this target can throw a Sil\EmailService\Client\EmailServiceClientException that should be excluded from this target to ensure a looping event is avoided.

As part of a Yii2 app configuration:

    'log' => [
        'targets' => [
            [
                'class' => 'Sil\JsonLog\target\EmailServiceTarget',
                'levels' => ['error'],
                'except' => [
                    'Sil\EmailService\Client\EmailServiceClientException',
                ],
                'logVars' => [], // Disable logging of _SERVER, _POST, etc.
                'message' => [
                    'to' => 'alerts@mydomain.com',
                    'cc' => 'noc@mydomain.com',         // optional
                    'bcc' => 'bcc@mydomain.com',     // optional
                    'subject' => 'Alert from application',
                ],
                'baseUrl' => 'https://emailservice.mydomain.com',
                'accessToken' => 'asdf1234',
                'assertValidIp' => true,
                'validIpRanges' => ['10.0.10.0/24','127.0.0.1'],
                'enabled' => true,
            ],
        ],
    ],

JsonFileTarget

The JsonFileTarget is just like the standard FileTarget except it accepts an array of data in the message and formats it as json before writing to a file.

As part of a Yii2 app configuration:

    'log' => [
        'targets' => [
            [
                'class' => 'Sil\JsonLog\target\JsonFileTarget',
                'levels' => ['error', 'warning'],
                'logVars' => [], // Disable logging of _SERVER, _POST, etc.
            ],
        ],
    ],

JsonSyslogTarget

The JsonSyslogTarget is just like the standard SyslogTarget except it accepts an array of data in the message and formats it as json before sending to Syslog.

As part of a Yii2 app configuration:

    'log' => [
        'targets' => [
            [
                'class' => 'Sil\JsonLog\target\JsonSyslogTarget',
                'levels' => ['error', 'warning'],
                'except' => [
                    'yii\web\HttpException:401',
                    'yii\web\HttpException:404',
                ],
                'logVars' => [], // Disable logging of _SERVER, _POST, etc.
            ],
        ],
    ],

Tips

Have the log prefix (if used) return JSON

Example (to be placed into your Yii2 config file's ['components']['log']['targets'] array):

[
    'class' => 'Sil\JsonLog\target\JsonFileTarget',
    'levels' => ['error', 'warning'],
    'except' => [
        'yii\web\HttpException:401',
        'yii\web\HttpException:404',
    ],
    'logVars' => [], // Disable logging of _SERVER, _POST, etc.
    'prefix' => function($message) use ($appEnv) {
        $prefixData = [
            'env' => $appEnv,
        ];
        if ( ! \Yii::$app->user->isGuest) {
            $prefixData['user'] = \Yii::$app->user->identity->email;
        }
        return \yii\helpers\Json::encode($prefixData);
    },
],

If using syslog to send to Logentries, only send the JSON content

Make sure that the template you define for Logentries in your rsyslog.conf file does not add other content before the %msg% data (aside from your Logentries key). For example, do something like this...

$template Logentries,"LOGENTRIESKEY %msg%\n"

... NOT like this...

$template Logentries,"LOGENTRIESKEY %HOSTNAME% %syslogtag%%msg%\n"
