secondly reviewing the WCPU percentage for the mgd process by running the following command:\n\nmgd process example:\n\nuser@device-re#> show system processes extensive | match \"mgd|PID\" | except

activity:\n\nWhile there is no specific command that shows a specific session in use for NETCONF, you can review logs for UI_LOG_EVENT with \"client-mode 'netconf'\"\n\nFor example:\n\nmgd[38121]:
