    New features and enhancements

    Installer

    On Windows, usage of legacy dtuser will be implicitly converted to Local System account during update.

    Log Monitoring

    The OneAgent log module is able to extract attributes from log content and enrich log records. The OneAgent log module now processes the enriched log data, improving performance. For details, see Connecting log data to traces (Logs Classic).

    OneAgent watchdog

    Two new parameters were introduced (currently used only in OneAgent Linux installation):

    • coredump.non_root_use_sigquit

      If set and watchdog is started with a non-root user (uid != 0), watchdog sends SIGQUIT signal to child process in case of ping timeout, memory exceeded, or shutdown timeout to trigger a core dump. Default: false

    • non_root_drop_capabilities

      If set and watchdog is started with a non-root user (uid != 0), watchdog drops all capabilities after initialization (before starting any child processes) and marks its own process as dumpable (prctl(PR_SET_DUMPABLE, 1)). Default: false
