help: set ironic inspect autodiscovery failed

Hi All, I'm trying the ironic inspect autodiscovery but failed. What I did:      Set the inspector.conf 1. [discovery] enroll_node_driver = ipmi [processing] permit_active_introspection = true processing_hooks = $default_processing_hooks,extra_hardware,lldp_basic Configure the python agent: inspection_callback_url: There's no node automatically added. I enter the host and read the log of python agent, no inspect related log. Could anybody give any advice about how to triage or setup correctly? Thanks & Regards, Wei
