Error rate - static threshold 🔗


This page explains how to use this condition when you are creating a µAPM detector. If you are creating an Infrastructure or Custom Metrics detector, see this page instead.

What this alert condition does 🔗

Alerts when the error rate goes above a specified percentage for a minimum number of requests.

When to use this alert condition 🔗

Use this condition when you want to be alerted based on a fixed value, as opposed to trends (for which you could use the Sudden Change condition). For example, if a 10% error rate is normal and acceptable, you might want to be alerted whenever the error rate is higher than 10%.

Basic settings 🔗

Trigger threshold and Clear threshold Number between 0 and 100, inclusive

Trigger the alert when the current value is more than this percentage.

Clear the alert when the current value is less than this percentage; must be lower than trigger threshold.

Advanced settings 🔗

Current window Integer >= 1, followed by time indicator (s, m, h, d, w), e.g. 30s, 10m, 2h, 5d, 1w The time range being monitored for errors. For example, a value of 10m indicates that you are looking for the percentage error rate for the most recent 10 minutes.
Minimum request volume Number >= 0 Minimum number of requests in current window; prevents alerts for sparse data.
