Stage 6

Alarm Health Audit

A practical scan of the Niagara AlarmService database. This report prioritises noisy alarm sources, active unacknowledged alarms, normal-but-unacknowledged records, repeated alarm counts, and database capacity risk.

Alarm database is near or at capacity

The database is using 100.0% of configured capacity. Noisy alarms may push older records out of the database. Export evidence before clearing records, then tune the repeat offenders first.

How to read this report

Findings are action items. A single alarm source can create multiple findings, such as repeat source, high count, active unacknowledged, or normal-but-unacknowledged.

Record count is how many records from that source are present in the current alarm database. Max Count is Niagara's alarm Count value and usually indicates repeated alarm transitions.
