Telemetry system extension

A method of operating a telemetry system includes automatically populating a base field of a schema in an event definition using a logging library of the telemetry system for an event of an instrumented application, and automatically populating a conditional field of the schema in the event definition using the logging library in response to a selected condition for the event. 种操作遥测系统的方法包括：针对插桩应用的事件，使用遥测系统的日志记录库自动填充事件定义中的模式的基本字段，并且响应于事件的选定条件，使用日志记录库自动填充事件定义中的模式的条件字段。
