Dear All, I hope you are doing great. I have successfully configured Barnyard2 to write to mysql and then Base picks up the information and displays correctly. I have then decided to add the option "output alert_fast tofile" and send that same file to Logstash. Barnyard2 is able to write correctly to that file but when Logstash displays it, it is missing the "reference"; "classification", "gen-msg" and "sid-msg" of the rule used. For example: Here is a logstash output: "[1:2010935:2] Snort Alert [1:2010935:2] [**] [Classification: Potentially Bad Traffic] [Priority: 2] {TCP} X.X.X.X:52727 -> X.X.X.X:1433" Now for Base, here is output for the same rule: "ET POLICY Suspicious inbound to MSSQL port 1433" It looks like barnyard2 doesn't read "reference"; "classification", "gen-msg" and "sid-msg" files when it comes to "output alert_fast". In the other hand, in Snort, if I use in command line option "-A fast", the output is fine for Logstash. Best regards, Tarek
