| 0 | Total Alerts | 20 | 0 | VT_COUNTER | Count | Total number of IDS alerts recorded for this individual signature within each 300-second (5-minute) collection interval. VT_COUNTER type — a running count for the bucket, not a cumulative all-time total. |
| 1 | Unused Cardinality counter | 20 | 20 | VT_GAUGE | Uniques | Reserved VT_GAUGE slot for a unique-value (cardinality) metric. Not currently mapped to any field for this counter group, so no data populates this meter — placeholder carried over from the counter-group template rather than something specific to this signature. |
| 2 | Unused Cardinality counter | 20 | 20 | VT_GAUGE | Uniques | Second reserved VT_GAUGE cardinality slot, identical in status to meter 1 — inactive, not instrumented for this group. |
