|---|---|
| Target | The covered area of the watched target that triggered the alert. Note: If the scope of the target is at the server or instance level (i.e. Q-REGRESSION and not Q-REGRESSION: SQL Server Agent Jobs), then it will be a hyperlink to display Health, Dashboards, or Top SQL for that target). |
| Type | The alert type, such as SQL Server, a deadlock (Deadlocks: Deadlock), etc. |
| Name | The name of the alert. |

| View | Select the Details hyperlink to view a popup window containing the details logged for the alert: The available details vary depending on the condition, and may contain information such as the step of a failed SQL Server Agent job and the error behind the failure .On an alert such as High CPU, which looks for CPU greater than 90, the performance counter value collected at the time of the alert evaluation is included (e.g. Performance Counter: Processor Information: % Processor Time, Total [97.4264] > [90] *TRUE* ). |

Email Notifications
You have the option to send alert emails when an alert's condition evaluates to True.
Important: SentryOne will send a maximum of 50 alert emails per day. This maximum is for all emails, across all alerts. It is recommended that you only configure email notifications for critical alerts that require a fast response so that you keep your overall emails to a minimum, and do not miss emails for more important alerts.
Select Send alerts for [Condition Name] to me at [email@address.com] to receive email notifications for the associated alert, at the default email address for your user name. A toast notification pops up to confirm the change. Deselect this option to disable email notifications for the associated alert, for your user name.
Use the Send alerts for [Condition Name] to these email adresses: option to enter additional email addresses that should receive alert emails.
- Enter an email address, or multiple email addresses (separated by a comma).
- Select Add.
- Once you have the email addresses entered, use the Back to Conditions button to save the changes.
Select the X after an additional email address to stop it from receiving alert emails for the associated alert.
Important: Changes to email addresses (adding or deleting) are not saved until you select the Back to Alerts button.
Note: You can send alert emails to yourself, others, or a combination of these emails.
Evaluation Status
Applies to the following products and features: The SentryOne Monitor product.
The Evaluation Status table is accessed by selecting a row from the Actions column in the Configuration table.
Note: The following columns are all read-only or hyperlinks.
| Column | Description |
|---|---|
| Object Name | The name of the target associated with the evaluation. Note: The hyperlink provides option to jump to other views for the target (e.g. health or dashboard). |
| Last Result | Displays the outcome of the most recent evaluation against the alert. The result will be True or False. Example: The High CPU alert checks for sustained CPU usage over 90%.
|
| Duration | The amount of time it took to evaluate the result of the alert. |
| Last Evaluation Time | The last time the evaluation completed. |
| Last Error | If there was an error during the evaluation attempt, it displays information here. |
| Evaluation Type | Displays whether the evaluation was executed as Scheduled or Manual. Each alert in SentryOne Monitor is set to evaluate at a frequency specific to the alert. Scheduled indicates that the evaluation was performed on schedule by the monitoring service. For example, the High CPU alert is scheduled to evaluate every 30 seconds, while the SQL Server Paged to Disk alert is scheduled to evaluate every 5 minutes. Manual means that a user chose to evaluate the alert ad-hoc through the configuration client. This is an infrequent Evaluation Type in SentryOne Monitor as users rarely need to access the configuration client. |
