Real-time change detection (RTCD) works as expected. This fix includes the following changes:

  • The program RTNForwarder.exe is no longer launched to download the updated configuration file. This program is still present on your SolarWinds Platform server, but it is not used.

  • The Log Viewer (LV) and Log Analyzer (LA) now include a new action called Real-Time Config Change Detection. This action is available only if NCM or Hybrid Cloud Observability Advanced is installed.

    In 2023.2.1 and later, this action is used (instead of Run External Program) in rules configured for real-time change detection. The Real-Time Config Change Detection action requires no configuration. You don't need to specify an executable or provide command line arguments.

During an upgrade, the installer makes the following changes:

  • Any LV or LA rules (preconfigured or custom) that performed the action of launching RTNForwarder.exe are automatically updated to perform the new Real-Time Config Change Detection action instead.

  • If there are any SolarWinds Platform alerts configured to launch RTNForwarder.exe as an action, that action is disabled.

Using Kiwi Syslog Server or a third-party syslog or trap receiver with RTCD is not recommended. If you are currently using anything other than LV or LA, SolarWinds recommends that you do the following after the upgrade:

  1. Have the syslog or trap receiver forward messages to the SolarWinds Platform server.

  2. In LV or LA, enable the default rule or configure custom rules to detect config change notifications. For more information, see Step 2 of Configure real-time change detection in NCM.
