Right now there is a fixed set of log types that get enriched by NetBox. This is for performance and storage reasons.

We ought to make this configurable, probably via environment variable. I'm not sure what the exact best answer is, but something with options like

  • (blank, or default) - use existing set of logs we're enriching today
  • all - enrich all logs
  • let them customize the list? e.g., zeek.conn,zeek.http,zeek.notice,suricata.alert,..., etc?

    * these variables in [`arkime.env`](https://github.com/idaholab/Malcolm/blob/main/config/arkime.env.example) to allow configuration of Arkime's ILM/ISM settings (#300)
