Hi Geoff, Thanks for the report. The Avg/Match isn't correct. We've created a bug to address this. Thanks again, Todd Geoff Whittington wrote:
Hello, We've been giving 2.8.3 a whirl specifically to use snort's metrics. The following is a sample output of a single run of snort against one pcap and one snort signature. Num SID GID Checks Matches Alerts Microsecs Avg/Check Avg/Match Avg/Nonmatch === === === ====== ======= ====== ===== ========= ========= ============ 1 151 1 36 36 36 20254 562.6 0.2 0.0 Since Checks=Matches=36 I would have expected Avg/Match to be 562.2, not 0.2. Is the documentation correct? Thanks, - Geoff According to the URL: http://www.snort.org/docs/snort_htmanuals/htmanual_283/node150.html The columns represent: * Number (rank) * Sig ID * Generator ID * Checks (number of times rule was evaluated after fast pattern match within portgroup or any-rules) * Matches (number of times ALL rule options matched, will be high for rules that have no options) * Alerts (number of alerts generated from this rule) * CPU Ticks * Avg Ticks per Check * Avg Ticks per Match * Avg Ticks per Nonmatch ------------------------------------------------------------------------ ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ------------------------------------------------------------------------ _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
