Abount netif.yml

When I added metadata: sec.zon.name to netifs.yml, the collector stopped receiving data. Then when I delete the data, I can receive the data normally . Please look at it for me

If the collector stops receiving data completely when you added the metadata definitions to the netifs.yml file then that seems to indicate there is something in the configuration preventing the collector from starting properly.

If the metadata tags are not being applied properly then that could be either a parsing issue or a bug.

You should review the logs when the collector is started with the metadata tags in netifs.yml to see if the collector has an issue starting when they are used. Be sure to check the system time just before the restart of the collector so that you can review the logs that come in after the restart time.
