vscode-microprofile has opt-in telemetry collection, provided by vscode-redhat-telemetry.
vscode-microprofile emits telemetry events when the extension starts and stops, which contain the common data mentioned on the vscode-redhat-telemetry page.
vscode-microprofile emits telemetry events whenever you apply a quick fix or source action, and emits an event if applying the quick fix or source action fails.
Use the redhat.telemetry.enabled setting in order to enable or disable telemetry collection.
Note that this extension abides by Visual Studio Code's telemetry level: if telemetry.telemetryLevel is set to off, then no telemetry events will be sent to Red Hat, even if redhat.telemetry.enabled is set to true. If telemetry.telemetryLevel is set to error or crash, only events containing an error or errors property will be sent to Red Hat.
