    Hi Juan Matthew ,

    Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

    We understand from your query that you are experiencing an issue while trying configuration of the Linux Diagnostic Extension.

    • Msgpack settings not set: The Msgpack settings (array size, map size, string size, bin size, ext size, and nesting) are not set, so default values are being used
    • The event ingestion rate limiting (EPS) is set to 20000 events per second.
    • /var/lib/waagent/Microsoft.Azure.Diagnostics.LinuxDiagnostic-4.1.10.lock was taken successfully.
    • The error message indicates that some GCS (Google Cloud Storage) environment variables are missing. Without these variables, GCS won’t be used.
    • XML configuration errors: There are three errors in the XML configuration file /var/lib/waagent/Microsoft.Azure.Diagnostics.LinuxDiagnostic-4.1.10/xmlCfg.xml:
      • Line 3: The MdsTime() function expects an RFC3339 date but received an invalid value 1751507743.
      • Line 25: No default credentials were defined.
      • Line 27: No default credentials were defined.
