Information About Advanced Threat Detection Statistics
Advanced threat detection statistics show both allowed and dropped traffic rates for individual objects
such as hosts, ports, protocols, or ACLs.
Caution Enabling advanced statistics can affect the ASA performance, depending on the type of statistics
enabled. Enabling host statistics affects performance in a significant way; if you have a high traffic load,
you might consider enabling this type of statistics temporarily. Port statistics, however, has modest
impact.
