Hey Eric sorry, i want to ask,how to send zeek all event to syslog collector?
Okay thanks eric for reference, I will try it, if there is a problem maybe I will discuss again with you here. Is there something I missed from the steps you listed here? Thank you, Julian.

For some background, CentOS 8 no longer ships with network-scripts support and requires the use of NetworkManager for network configuration.
However, NetworkManager does not provide the level of configuration required to optimize sniffing interfaces for packet capture, hence the need for the now legacy, network-scripts. You can however run it such that NetworkManager is used for your management interfaces, and network-scripts are used just for the sniffing interfaces.
All that said, you have two choices: 1. Re-enable NetworkManager. For most people, the easier option will be number 1. To start and re-enable NetworkManager, run:. Hi Eric, I did that and it worked.

Zeek interprets what it sees and creates compact, high-fidelity transaction logs, file content, and fully customized output, suitable for manual review on disk or in a more analyst-friendly tool like a security and information event management SIEM system. The project welcomes contributions of all kinds: documentation, code, feature requests, offers to spread the word about Zeek… even cupcakes!
