Control the minimum number of occurrences of a query required before a hour pattern can be detected.
Can be set in: collection.cfg
This option specifies the minimum (average) number of queries required per hour before a particular query can be detected as a trend alert. Collections with a high query volume may wish to raise this value to eliminate patterns caused by random fluctuations in relatively uncommon queries.
The default value is set to 5, meaning an average of five queries per hour over the period is required.
