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)
      • The associated grammar types (eg. none, doctype, xml-model, xsi:schemaLocation, xsi:noNamespaceSchemaLocation)
      • The resolver used to resolve the grammar identifier (eg. catalog, file association, embedded catalog.xsd, embedded xml.xsd, embedded xslt.xsd)
