Previously, Icinga 2 logged to the shared "Application" log provided by default. Due to the comparatively high volume of log messages, this lead to complaints and for the early logging (before the final logging configuration is loaded and enabled), the behavior isn't configurable easily. By using our own log file, this should be less annoying for users. The log is named "Icinga 2" and the source "Icinga 2 General" because according to the documentation, these names should not be the same: "You cannot use a source name that has already been used as a log name." [1] This naming allows for distributing messages across different sources in the future (think "Icinga 2 ApiListener", "Icinga2 CheckerComponent", ...). However, this requires registering all these names in the registry, so this is just left as an option for now. The existing "Icinga for Windows" log is not used on explicit request.

About
Icinga is a monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.
Scalable and extensible, Icinga can monitor large, complex environments across multiple locations.
Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. The configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL.
