Hermod

Simple pre-configured Grafana Loki logging and exception handling for Neos

📦 Packagist • Quick Start • Functionality

Quick Start

Important

This package pre-configures the Neos Flow systemLogger and securityLogger as well as the exceptionHandler.

Just add these environment variables and you are good to go:

  • LOKI_URI: the URL to your Loki instance
  • LOKI_USER: Username
  • LOKI_TOKEN: Access Token

Functionality

Logging Backend

A buffered logging backend.

Class: SJS\Hermod\Log\Backend\LokiBackend

Options

Example

Configuration/Settings.Neos.Flow.yaml

Neos:
  Flow:
    log:
      psr3:
        'Neos\Flow\Log\PsrLoggerFactory':
          systemLogger:
            default:
              class: SJS\Hermod\Log\Backend\LokiBackend
              options:
                severityThreshold: "%LOG_DEBUG%"
                url: "%env:LOKI_URI%"
                user: "%env:LOKI_USER%"
                token: "%env:LOKI_TOKEN%"
                maxBufferSize: 300
                labels:
                  target: systemLogger

Exception Handling

Production Class: SJS\Hermod\Handler\ProductionExceptionHandler

Debug Class: SJS\Hermod\Handler\DebugExceptionHandler

Options

The exception handling is split into two parts. The Exception Handler uses the Exception Service to send the data to Hermod.

  Flow:
    error:
      exceptionHandler:
        className: SJS\Hermod\Handler\ProductionExceptionHandler

        defaultRenderingOptions:
          lokiIgnoreException: false
