Alert logs

Some user profiles don't have access to the Alert logs page.

To go to the Alert logs page, click the alerts icon  at the top right corner of the Portal.

Use the Alert logs page to review the alerts that have been triggered by tests in your account. You can filter the table to focus on the alerts you're particularly interested in, for example:

  • All alerts for a specific test, to troubleshoot that test.
  • Alerts within a given time frame to look for patterns of time- or date-specific events.
  • Alerts of a specific type, if you're analyzing a performance issue such as slow response time or incomplete page loads.
  • Alerts for a specific test type.

The Alert logs page is refreshed to list the latest alerts as soon as you go to it. The alert count listed at the top of the page may not be the same as the number in the alert icon because the icon is only refreshed every 5 minutes. The alert icon lists the number of active alerts from the last 24 hours. The alert count in the Alert logs page may also differ because when you select a time frame other than 24 hours, the time frame for the alert icon doesn't change.

Alert summary

The Alert logs table gives you summary information about the alerts.

Test and browser icons

Each test is identified by product (test type). Performance tests are also identified by Browser Agent.

Test type

Backbone test icon Backbone

Private Last Mile test icon Private Last Mile

Availability test icon Availability

Browser Agent

IE Agent icon Internet Explorer

Firefox Agent icon Firefox

Chrome Agent icon Chrome

Mobile Agent icon Mobile


If a test name is truncated to the column width, hold the mouse pointer over it to display the full name.

Alert time

The alert time is the date and time the threshold was triggered. The displayed time is based on the time zone configured for your account.

By default, the table lists alerts from most recent to oldest.

Alert type

The alert type may be one of the following.

  • Response time
  • Step response time (available for Backbone tests)
  • Transaction failure
  • Step transaction failure (available for Backbone tests)
  • Page object error
  • Byte limit exceeded

For more information, see Types of Performance test alerts.


The alert progression can be one of the following:

  • Initial – The alert was triggered when the test first exceeded the alert thresholds.
  • Reminder – The condition is not resolved; reminders are sent if they were configured for the alert.
  • All Sites – The condition that triggered the alert occurred on all measurement locations used by the test.
  • Condition improved – The issue that triggered the alert is resolved and test performance has returned to normal.
  • Sample – A sample alert was sent to validate the alert destination.

Viewing alert details for a Performance test

To see details about an alert, click the alert time. For more information, see Alert details.

Alert details aren't relevant to Availability tests. Clicking the alert time for an Availability test alert takes you to the Test overview page for that test.

Modifying an alert

Click the edit icon in the alert's row to go to the alert settings in the Edit a <TestType> Test page. For details, see Test settings.

Filtering the alerts table

Use the filters to refine the table contents so you can focus on the alerts of most interest to you.

Show inactive alerts

By default, the table is filtered to Show active alerts only. An alert is active as long as the condition that triggered the alert isn't resolved. The alert becomes inactive after the test progresses to Condition Improved. Sample alerts are also inactive. To list all alerts including Sample and Condition Improved, click the Show active alerts only switch to disable the option .

Alerts aren't triggered for inactive measurement locations.

Change the time frame

The default time frame is Last 24 hours. To view alerts for a different time frame, click the time icon and select the time, from the last 5 minutes through the last 45 days.

The Last week option displays alerts for the last full week, Sunday through Saturday.

Last month displays alerts for the last full month, to a maximum of 45 days before the current date. For example, on July 1 through 15, alerts are listed for all of June; on July 28, however, alerts are listed beginning with June 14 (45 days before July 28) through June 30.

Find alerts by test name

Enter a string in the Filter tests field to list only the test names that contain that string. The filter string can be anywhere in the test name.

Use the alert filters

Use the filters on the left side of the page to refine the alerts table by alert type, progression, and test type. You can select more than one item in each filter category. For example, you may want to view Initial and All sites alerts.

When you select a filter, it is highlighted with blue text. To remove a filter, click it again; or click All at the top of the filter pane to remove all alert filters.

Drilldowns for data analysis

You can drill down from the Alert details page to the Trend details page and from there through the analysis workflow to the Waterfall summary page; or directly to the Waterfall summary page. For more information, see Alert details and Analysis workflow.
