The Azure Cosmos Repository follows the high performance logging guidelines making use of LoggerMessage throughout the library.

This page details what logs we offer and also what EventId ranges we have chosen to use.

Event ID Ranges

Since this library is making use of EventId’s each message we log falls within a range. We have split this range based on the common logging levels you would be use to seeing in any normal applications using ILogger. See the ranges below.

Log Level EventId range
Debug/Verbose 15000 - 15100
Information 15101 - 15200
Critical 15401 - 15500
Warning 15201 - 15300
Error 15301 - 15400
