What happens if my thresholds are too sensitive (false positive alerts)?

Use Statistics to analyze actual patterns and adjust thresholds. False positive symptoms: Alerts firing during legitimate low-volume periods (weekends, holidays, after-hours), minor variances trigger alerts (order volume fluctuates 745-855/hour, threshold Min 800 triggers intermittent alerts).

Tuning process:

  1. Collect 2-4 weeks of Statistics: Review average message counts, standard deviation, Min/Max observed values, day-of-week patterns
  2. Identify false positives: Check alert history, correlate alerts to business events (did order volume actually drop, or normal Saturday low volume?)
  3. Adjust thresholds: Set Min threshold to 80% of average (allows 20% variance), set Max threshold to 150% of average (50% buffer for peaks). Example: Average 847 orders/hour → Min 678 (80%), Max 1,271 (150%)
  4. Refine business hours: If false positives occur weekends, change schedule from "7 days/week" to "Mon-Fri only", set separate weekend thresholds (lower Min)
  5. Add exclude dates: Import company holiday calendar (Thanksgiving, Christmas, New Year's), exclude from evaluation
  6. Use Warning vs. Error thresholds: Set Warning at 85% of average (early heads-up, low urgency), Error at 70% of average (critical data outage, high urgency). Reduces alert fatigue (fewer critical alerts)

Statistics-driven example: Manufacturing production monitoring showed 12 false positive alerts/week (every Saturday/Sunday = "Machine Idle >60 minutes" alerts during scheduled no-production days). Solution: Added exclude dates Sat-Sun, false positives dropped to zero, alert accuracy 100%.
