detecting-anomalies

You can detect time-series anomalies by applying statistical outlier methods like Z-score and IQR to flag unusual latency, error counts, or throughput. These calculations surface spikes, drifts, and outliers in your monitoring data.

The best way to identify sudden spikes and trend shifts is by using change-detection patterns such as rate-of-change and moving-average deviation. These methods effectively spot rapid deviations from established data trends over a specific time window.

Yes, you can use OPAL to configure threshold and percentile-based alerts to enforce SLOs and capacity limits. It applies standard statistical methods to time-series data, requiring no external installation beyond the existing OPAL tooling.

To reduce false positives when monitoring throughput for outliers, use noise-robust detection and multi-method consensus. Combining multiple statistical techniques like moving averages and Z-score helps filter out irrelevant data noise.

No, you do not need to install external dependencies to apply Z-score anomaly detection. The process uses standard OPAL tooling and built-in statistical methods to analyze time-series metrics without extra setup.
