Adapter and Collector Log Files

You can review adapter errors in the adapter and collector log files, which can be viewed in the VMware Aria Operations UI or in an external log viewer.

  • Adapter log files are located in the $VCOPS_BASE/user/log/adapters/NetworkingDevicesAdapter/ folder.

  • Collectorlog files are located in the $VCOPS_BASE/user/log/ folder.

To set the base log level for the collector in VMware Aria Operations:

  1. Navigate to Administration > Logs.

  2. Expand the PRIMARY folder, then select the COLLECTOR folder.

  3. Click the Edit Propertiesicon.

  4. In the Root logger level drop-down menu, select the desired option.

  • The default logging level is warning.

  • To troubleshoot issues, set the logging level to info.

  • To view detailed messages, including micro steps, queries, and returned results, set the logging level to debug.

    Caution:

    If you set the logging level todebug,log files can become large very quickly. Set the logging level todebugonly for short periods of time.

For more information about viewing log files and modifying levels, refer to the VMware Aria Operations online help.
