This is a simple script to introspect all Zeek logs and output field name, type, and description information. The default output format is CSV files.
Via zkg:
zkg install jsiwek/zeek-print-log-info
Manually:
cd <prefix>/share/zeek/site git clone https://github.com/jsiwek/zeek-print-log-info
Run the following command:
ZEEK_ALLOW_INIT_ERRORS=1 zeek zeek-print-log-info
There is a lot of extraneous output because it's loading and parsing a lot of scripts that aren't necessarily meant to be loaded in this fashion, but otherwise should write *.csv files in the current directory just fine.
