On the Alerts tab within the device interface, you can configure the delivery of the device alerts.
You can create and configure custom notification groups with different types of alert addresses to receive alerts.
In the Send Alerts to Group(s) section, you can assign one or more alert groups to the monitored device. To add a new address, click the Add Group button and select the necessary check boxes.
To enable an alert for a group based on the duration of an error, select an error duration time in the Escalation field for this group. The alert will be sent to the selected group only if the error condition persists during a specified time. The escalation time intervals range from immediate to three hours and are available in 10-minute increments. For details, see the Escalation article.
When an error is detected, we run series of checks to ensure it is not a false alert. Those checks may take some time, depending on the error type and a number of tasks in the device. This may cause some delay in downtime alert.
You can disable False Positive Check to ensure immediate downtime alert, but it may result is some “false” alerts. For more details, see False Positive Check.
To receive notifications when a device begins successfully completing tasks after a failure, select the Send Uptime Alert check box. For more details, see Uptime alerts.
To determine how monitoring alerts are processed or displayed, in the Alter filter field, select the filter to apply to alerts.
Ignore an Error if the following error conditions apply: You can specify multiple filters to help eliminate false positives and excessive alerts.
Error is reported for less than x minutes: Errors will be suppressed until the number of minutes specified has passed between failing errors.
Error is not confirmed by at least x monitoring locations: Errors will be suppressed until the error has been confirmed by x number of locations.
Error is detected in less than x tasks: The error will be suppressed until x number of tasks have confirmed the error. (These must be tasks included within the same device. Tasks from multiple devices will not be considered valid in this filter.)
Error if Owner Device is Down: If you have selected an Owner Device for a particular device, errors for the device this filter is applied to will be suppressed if the owner device is currently returning errors or is unavailable.
In the Minimum Number of Minutes Between Alerts fields, you can set the throttling option.
To adjust the number of minutes that will elapse before the system generates another alert, enter the necessary value in the related address type field.
This may be particularly beneficial when sending alerts to devices with the additional cost such as pagers or phones not in the USA.
