If java.telemetry.enabled is set to true, JDT-LS emits telemetry events.
These events can be collected by the LSP client program.
When telemetry events are enabled, the following information is emitted :
- The name of the build tool used to import a project (eg. Maven, Gradle, Invisible (project), etc.)
- The total number of Java projects within the workspace
- The lowest and highest Java compiler source level used (eg. 11 & 17)
- Whether the project(s) are being imported for the first time (eg. true)
- The elapsed time (in milliseconds) at which the language server initialized the workspace project(s), declared as ready for requests, and completed building the project(s)
- The number of libraries that were indexed after project initialization
- The total size (in bytes) of libraries that were indexed after project initialization
