vscode-java has opt-in telemetry collection, provided by vscode-redhat-telemetry.
- vscode-java emits telemetry events when the extension starts and stops, which contain the common data mentioned on the vscode-redhat-telemetry page.
- 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
- The number of error markers on the project(s)
- The number of unresolved imports within the project(s)
- Errors relating to running the language server, such as the message & stacktrace
- Whether there is a mismatch between the project's requested source level, and the JDK used for the project (eg. true)
- Information about the following settings. In the case of settings that store a well defined value (eg. path/url/string), we simply collect whether the setting has been set.
java.settings.url
,java.format.settings.url
,java.quickfix.showAt
,java.symbols.includeSourceMethodDeclarations
,java.completion.collapseCompletionItems
,java.completion.guessMethodArguments
,java.completion.postfix.enabled
,java.cleanup.actionsOnSave
,java.sharedIndexes.enabled
,java.inlayHints.parameterNames.enabled
,java.server.launchMode
,java.autobuild.enabled
,java.jdt.ls.javac.enabled
- The extension name and the choice made when a recommendation to install a 3rd party extension is proposed
- The name of Java commands being manually executed, and any resulting errors
- The number of results (eg. 20), whether an error occurred (eg. false), engine type (eg. 'ecj', 'dom') and duration (in milliseconds) when code assist is activated
- Whether the language server ran out of memory and the maximum allocated memory at which that occurred (eg. 200m)
Please see the vscode-redhat-telemetry data collection information for information on what data it collects.
Use the redhat.telemetry.enabled
setting in order to enable or disable telemetry collection.
This extension also 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.
