WebNov 1, 2024 · It roughly calculates the following: . rate (x [35s]) = difference in value over 35 seconds / 35s. . The nice thing about the rate () function is that it takes into account all of the data points, not just the first one and the last one. There is another function, irate, which uses only the first and last data points. Webpredict_linear() This function receives a range vector and a scalar time value as arguments. It extrapolates the value of each matched time series from the query evaluation time to …
WebJul 23, 2024 · Using boundaries of ±2σ on either side of our prediction is a pretty good measurement for determining an outlier with seasonal predictions. How to set up alerting using Prometheus If you want to set up alerts for anomaly events, you can apply a pretty straightforward rule to Prometheus that checks if the z-score of the metric is between a …
