Architecture

Nebula Logger is built natively on Salesforce - everything is built using Apex, lightning components and various types of objects.

As shown in the above diagram, all of the metadata is broken down into 4 layers/modules:

1. Logger Engine Layer

The core of Nebula Logger that makes logging work. Currently, logging is supported for:

• Apex
• Lightning web components & aura components
• Flow, including a generic Flow log entry, a record-specific Flow log entry, and a collection-specific Flow log entry

This layer includes 1 platform event object:

• LogEntryEvent__e platform event

2. Log Management Layer

This provides the ability to view and manage logging data, using the Logger Console lightning app. This layer includes 4 custom objects:

• Log__c custom object
• LogEntry__c custom object
• LogEntryTag__c custom object
• LoggerTag__c custom object

3. Configuration Layer

Admins, developers, and architects can control & customize Nebula Logger's built-in features, using custom settings, custom metadata types, and permision sets. This layer includes:

• Custom Hierarchy Settings
  • LoggerSettings__c for user-specific configurations
• Custom Metadata Types
  • LoggerParameter__mdt for system-wide key-value pair configurations
  • LogEntryDataMaskRule__mdt for configuring regex-based data masking rules
  • LogStatus__mdt for configuring which picklist values in Log__c.Status__c map to IsClosed__c and IsResolved__c
  • LogEntryTagRule__mdt for configuring tagging rules
• Permission Sets
  • LoggerAdmin
  • LoggerLogViewer
  • LoggerEndUser
  • LoggerLogCreator

4. Plugin Layer

This layer provides the ability to add new functionality to Nebula Logger by creating or installing plugins. Currently, a plugin is available for Slack, and other plugins are in development. Plugins can be built for any of the 5 included objects

• LogEntryEvent__e platform event
• Log__c custom object
• LogEntry__c custom object
• LogEntryTag__c custom object
• LoggerTag__c custom object
