Will trigger when value exceeds this threshold for 5 minutes
How to Use This Calculator
1. Metric Name: Identify what you're monitoring (e.g., "CPU Utilization", "Database Latency").
2. Alert Type: Choose whether high values, low values, or both should trigger alerts.
3. Sensitivity: Select how sensitive your alerts should be:
- Low (3σ): Fewer alerts, only extreme outliers
- Medium (2σ): Balanced approach (default)
- High (1σ): More alerts, catches smaller anomalies
4. Time Window: Set how long the threshold must be breached before alerting.
5. Data Points: Enter historical values for your metric to calculate baseline statistics.
Statistical Method
The calculator uses standard deviation (σ) to determine thresholds:
Upper Threshold: mean + (sensitivity × σ)
Lower Threshold: mean - (sensitivity × σ)
This method assumes your data follows a normal distribution. For non-normal distributions, consider using percentiles instead.
