 # Trace telemetry: Application Insights data model
 
-Trace telemetry (in [Application Insights](./app-insights-overview.md)) represents `printf` style trace statements that are text-searched. `Log4Net`, `NLog`, and other text-based log file entries are translated into instances of this type. The trace does not have measurements as an extensibility.
