Data collection

vscode-xml has opt-in telemetry collection, provided by vscode-redhat-telemetry.

What's included in the vscode-xml telemetry data

  • JVM information:
    • Whether LemMinX is being run with Java or as a GraalVM native image (binary)
    • The name of the vm (java.vm.name)
    • The name of the runtime (java.runtime.name)
    • The version of the JVM (java.version)
    • The free, total, and max VM memory
  • LemMinX Version information:
    • The server version number
  • Does NOT include the JAVA_HOME environment variable for privacy reasons
  • The value of the xml.server.preferBinary setting
  • A telemetry event is sent every time the binary server download succeeds, fails, or is stopped by the user
    • If the download fails, the associated error is attached to the telemetry event
  • A telemetry event is sent every time you click the "Open Proxy Configuration Documentation" link that is provided when the language server binary download fails due to a proxy related issue.
  • A telemetry event is sent every time you click the "Download Java" link that appears when you have LemMinX extensions installed but don't have Java installed.
  • A telemetry event is sent every time the Java XML language server crashes due to an Out Of Memory Error, which also contains the maximum heap space for the JVM (-Xmx) that you've set.
  • A telemetry event is sent every time you click on the link to the documentation that appears after the Java XML language server crashes due to an Out Of Memory Error.
  • Text Document Information
    • When a document is opened :
      • The file extension (eg. xml, xsd, dtd, rng)
      • The associated grammar types (eg. none, doctype, xml-model, xsi:schemaLocation, xsi:noNamespaceSchemaLocation)
      • The grammar identifiers for an XML document (eg. http://maven.apache.org/xsd/maven-4.0.0.xsd)
      • The resolver used to resolve the grammar identifier (eg. catalog, file association, embedded catalog.xsd, embedded xml.xsd, embedded xslt.xsd, relaxng.rng)

What's included in the general telemetry data

Please see the vscode-redhat-telemetry data collection information for information on what data it collects.

How to opt in or out

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.
