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
