How to Find the Source of an Alert

This article describes the steps for tracking down what triggered an alert. To understand how alerts work, see Alerts.
To understand the root cause of an alert you receive from the ThousandEyes platform, use the details of the alert to interpret what thresholds triggered it. You can look up the details of an alert from the Alert List widget in a dashboard, or from Alerts > Alert List.

Looking Up Alerts from a Dashboard

The Dashboards screen is available as the default page when you log in to the ThousandEyes platform. If your dashboard includes the Alert List widget, click the name of the active alert in the Alert Source column (see figure below). A new tab opens, showing the details of the active alert.
(1) Click the name of the active alert

    Having located the alert, use the Impacted Tests column to see the test that is associated with the alert rule that was triggered. You can also see related metrics that help show why this alert rule was triggered.

    Click the stack icon to the right of an impacted alert trigger (e.g., agent or monitor) to view the test results in a separate tab for that specific alert trigger. The test results offer a timeline view of the alert activity.

Reducing Noise in Alerts

If an alert is throwing notifications that exceed your operational requirements, you can adjust the alert condition thresholds.
  1. 1.
    Go to Alerts > Alert Rules.
  2. 2.
    Select the name of the alert rule that you want to adjust.
  3. 3.
    On the Settings tab, in the Alert Conditions section, review the current thresholds.
  4. 4.
    Make changes to these settings to reduce the frequency of alerts, according to your requirements.
After you adjust a noisy alert to meet your service-level expectations, the alert should begin to clear. An active alert that clears is moved to the Alert History tab. To view cleared alerts, go to Alerts > Alert List > Alert History.
