Logging

This section describes logging configuration, that can be applied for below Lime-CRM server services:

• Web Server
• Search Indexer
• Event Handler
• Task Handler
• Task Scheduler
• Importer

Logging can be configured through environmental variables and the application configuration. Environmental variables take precedence over the application configuration.
