Alerts

Alerts can be set up and managed for any entity type, and enable you to be notified when some specified attribute of an entity or entities changes in a predefined way.

Create an alert

To create an alert for an entity:

  1. Click Alerts in the left column, then click Alert Settings.

    The Alert Settings window is displayed showing all alerts that are currently active.

  2. Click Create Alert in the upper right corner.

    In the Logs Explorer, click the Create alert for this search query icon to create a new alert.

    The details tab of the create alerts page is displayed.

  3. Enter a name and description for the alert, and select whether you want it shown as Critical, Warning or Info.

    If you do not want the alert to be enabled immediately, disable it using the slider. The alert can be enabled from the Alert Settings page.

  4. Click Next to move to the Conditions tab.
  5. Select either a Metrics condition or a Logs condition.

  6. Select the entity type, scope, and selection criteria. The Scope by drop-down menu enables you to select a specific entity or select multiple entities by entering a string of characters that must be or must not be in the entity name.

    The number and percentage of entities contained in the scope are displayed in the Overview.

  7. To list and review the entities and their health statuses, click Show All Entities in Scope.
  8. Under Define a condition, click the condition box to start defining the first condition for this alert.
    1. Select the metric on which this condition is based from the Metric drop-down menu. All the metrics available for the selected entity type are displayed. When selected, a graph showing the behavior of this metric is displayed for each of the selected entities. The time period for this graph can be selected from the drop-down menu. You can show or hide the metrics for a particular entity by clicking the name in the legend beneath the graph.
    2. (Optional) Click Add tags to include or exclude specific metric tags.
    3. In the Aggregate on drop-down menu, select the aggregation method (such as average, maximum or minimum) to apply to this metric.
    4. From the Trigger when metric is drop-down menu, select the operator (such as equal to, higher than or lower than) to apply to the aggregation, and enter the value for the operator.
    5. Enter the value and time frame to complete the condition that must be met for the alert to be triggered.

    After entering a condition, the icons before each entity will show whether an entity would trigger the alert or not in the selected period. In the example below, only the bz-test-web website would trigger the alert as the maximum response time has been over 250 ms for at least two minutes on one or more occasions in the last hour.

  9. To add another condition, click Add new condition and repeat step 7.
  10. When you finish setting up the conditions for the alert, click Next to move to the Notification tab.
  11. Click Add and select the Notification service you want to be used when this alert is triggered.

    This can be Email, Microsoft Teams, Slack or Webhook.

    For each method, select a name and description, and further settings appropriate to each method.

  12. Add further Notification services if required, then click Next to go to the Summary.
  13. Ensure the conditions and notification settings are correct (click Previous to navigate back to appropriate pages if required), then click Create.

The alert page for this alert is displayed.
