Understanding Sensitivity Analysis — Tune Thresholds with Confidence
The Sensitivity tab in ThresholdIQ helps you answer one of the most important monitoring questions: “What happens to my alert volume if I tighten or relax my thresholds?” Instead of guessing, you get a clear, data‑driven view of how your system behaves under different threshold scenarios.
Why Sensitivity Analysis Matters
Thresholds are powerful — but they’re also tricky. Set them too tight and you drown in alerts. Set them too loose and you miss real issues. Sensitivity Analysis shows you exactly how your alert volume changes as thresholds shift, helping you tune your monitoring strategy with confidence.
1. Summary Metrics
At the top of the Sensitivity tab, you’ll see a quick snapshot of your dataset:
- Total Rows — how many data points were analyzed
- Alerts Fired — number of alerts under your current threshold
- Alert Rate (%) — percentage of rows that triggered alerts
- Severity Breakdown — how many alerts were Emergency, Critical, or Warning
2. Daily Alert Count
This bar chart shows how many alerts fired each day for the selected measure. It helps you identify:
- Days with unusual spikes
- Patterns of instability
- Operational periods where issues cluster
Consistent spikes often indicate a recurring operational issue or a threshold that needs adjustment.
3. Sensitivity “What‑If?” Analysis
This is the core of the Sensitivity tab. ThresholdIQ recalculates your entire dataset using hypothetical thresholds:
- -30%, -20%, -10% — tighter thresholds (more alerts)
- Current — your actual configuration
- +10%, +20%, +30% — looser thresholds (fewer alerts)
This lets you see how alert volume changes as thresholds shift.
4. Top Alert Windows
This section highlights the hours with the highest concentration of alerts. It’s especially useful for operational datasets where issues follow time‑based patterns.
- Recurring problem hours
- Night‑time instability
- Shift‑based operational issues
If you consistently see alerts at the same hour, that’s a strong signal to investigate upstream processes.
Putting It All Together
The Sensitivity tab gives you a complete picture of how your system behaves under different threshold conditions. It helps you:
- Reduce alert fatigue
- Tune thresholds intelligently
- Understand system stability
- Make data‑driven decisions
