The meaning of the individual fields:
- Ticks – total ticks spent on this rule, so a sum of all inspections
- % – share of this single sig in the total cost of inspection
- Checks – number of times a signature was inspected
- Matches – number of times it matched. This may not have resulted in an alert due to suppression and thresholding.
- Max ticks – single most expensive inspection
- Avg ticks – per inspection average, so “ticks” / “checks”.
- Avg match – avg ticks spent resulting in match
- Avg No Match – avg ticks spent resulting in no match.
The “ticks” are CPU clock ticks:
