Private Last Mile alert settings

You can create these test level alerts for Private Last Mile tests:

Default values for new alerts are defined in the test defaults.

You can't create alerts as part of provisioning a new test. After the test is created, open the editing page for the test to define the alerts.

Configuring alert settings

  1. In the Edit a Private Last Mile Test page, select the Test Level Alerts tab.
  2. The Response Time Alerts configuration screen is displayed by default. To configure a Transaction Failure alert, scroll to the bottom of the page and click Transaction Failure Alerts.
  3. Complete the alert settings as described below.
  4. Add notifications as described below.
  5. Click Update to save the settings and continue editing the test, or Update and Finish to save the settings and return to the Tests page.

Alert settings

Response Time alerts

Activation

Select On to enable the alert, or Off to disable it.

Test thresholds for error conditions

  1. Optionally, in the Exclude measurements from locations with bandwidths less than field, enter the number of Kbps to exclude measurements from locations when bandwidths fall below this value.

  2. Select the Dynamic, Static, or Average threshold type, then define the severity levels.
    A Warning threshold must have a lower value (in either percentage or number of seconds) than the values for a Severe alert.

    • Dynamic – Trigger an alert if the current average for the past hour is either an absolute number of seconds or the specified percent greater than the historical average (the past 1 day).
      You cannot edit the current or historical average window.
    • Static – Trigger an alert if a percentage or a specific number of peer tests exceeds the specified number of seconds.
      Enter either the percentage of tests or the specific number of tests to use to calculate the alert threshold.
    • Average – Trigger an alert when the average response time of tests executed in the past hour exceeds the defined threshold.

For more information on these threshold types, see Alert Thresholds.

Transaction Failure alerts

Activation

Select On to enable the alert, or Off to disable it.

Thresholds

  • Minimum Percentage of Peers (%) – Set the threshold as a minimum availability percentage. An alert is triggered when availability for the last hour falls below the specified percentage.
  • Number of Peers – Set the threshold based on the number of test locations with transaction failures. An alert is triggered when the number of peers with transaction failures exceeds the specified number.

Notifications

Use the Notifications section of the alert settings to specify who should be notified for the alert, and whether reminders should be sent until the test returns to "Good" status.

Use these options to help you determine where to send alert notifications:

You can define as many notifications as needed for the people who need to be notified when the alert is triggered. Repeat these steps for each notification:

  1. Click Add Notification to display the configuration fields.

  2. Select the Level of notification to configure. The level options depend on the alert type:

    • Response Time – Improved, Warning, Severe
    • Transaction Failure – Improved, Failed
  3. Select the destination for this alert.
    The Destination list includes all alert destinations defined for your account, plus the built-in destination mobile application (push notification) to send notifications to a mobile device through the Dynatrace Synthetic Mobile app.
    If no destination is selected, the alert is sent to the alert log only.

  4. When you select an email destination, the subject line for that destination appears in the field below the alert destination. If necessary, modify the subject line. For more information about defining the subject line, see Alert Destinations.

  5. To send reminders, select Send Reminders, then select a frequency from the Reminders Frequency list. The default setting is never (don't send any reminders).

    • Reminders can only be sent to an alert destination; they cannot be sent if you select no destination (alert log only).
    • Reminders cannot be sent for Improved alerts.
    • Reminders will be sent until the test returns to "Good" status. Set the reminder so that at least one test run can occur before a reminder would be sent. For example, if the test frequency is every 15 minutes and the reminder frequency is only 5 minutes, reminders will be sent before the next test run shows whether the test is still in an alert status or has improved.

To stop sending notifcations to a destination, select no destination (alert log only) in the Destination/Subject list for the destination.
