Hello, I'd like to throw another alternative and some comments into this thread. Am 22.04.2009 um 04:38 schrieb Paul Schmehl:

Whether snort feeds mysql directly *or* barnyard parses the unified format and feeds mysql, the result is the same - events are entered into the *snort* database. The BASE install adds the four acid_* tables. Those tables are fed by base, not by snort or barnyard. So, if the snort db event table has entries but the acid_event table does not, the problem is BASE not snort, mysql or barnyard.
Both direct Snort DB insertion as well as Barnyard require the BASE caching process (which basically aggregates data from 'tcphdr, udphdr, icmphdr, event, sensor and signature' into 'acid_event') in order to consolidate the data inserted by (possibly) multiple Snort or Barnyard deployments. At OSSIM we changed this behaviour and aggregate events at correlation engine level, receiving data from multiple agents (which in turn parse multiple snorts logging using unified format), aggregating it and filling in all the tables from a central point, removing the caching process and thus enabling realtime visualization of that data. Our requirements, both in terms of performance and data visualization made us maintain a patch against BASE for many years, but we recently decided to fork it into our codebase since it would be easier to maintain. You're more than welcome to give it a shot.
