Alerts
The alert is a notification that a rule is violated.
On the Alerts page you can:
- View the number of critical, warning, and information alerts for all the solutions for the selected time range
- Filter the alerts by solution, runtime, severity, and status
- Configure the rules by adjusting the alert threshold values
- Configure the summary of the alerts
- Configure the recipient email based on alert severity. For more information about configuring alerts, see Configuring the Alerts.
By default, the alerts page displays the number of alerts (critical, warning, and information) for all the solutions, and detailed information about the alerts in a tabular format.
The alert does not appear immediately when the corresponding rule violation occurs. The system will wait for a certain duration between the violation of the rule and the firing of the alert. In this time period, the system will check whether the alert continues to be active during each evaluation for that time period before firing the alert. The evaluation time for different alerts is as follows:
5 seconds for run-time availability rules(Critical alert will be fired only if runtime is unavailable for more than 5 seconds).
180 seconds for run-time availability rules(Information alerts for one or more instances of clustered products will be fired only if they are unavailable for 180 seconds).
60 seconds for the rest of the rules(Alerts will be fired only when rules are violated more than 60 seconds).
The system will not send an alert if the rule violation condition is resolved during the corresponding evaluation period.
If you deactivate a solution, the Alerts page will not display the alerts for the solution.
If you activate a solution, the Alerts page will display both the historical alerts for the solutions that had been raised before the deactivation of the solution, and the alerts that were raised after the activation of the solution.
When a solution update starts, the existing active alerts for the solution are set to resolved. During the update period, no alerts are generated for the solution. You can disregard any email alerts that you receive during the upgrade period.
The following table describes the information that is displayed in the table on the Alerts page.
