Editing alerts

You can edit the alert details such as threshold, target instances, alert conditions, and notifications. You can edit the alerts created through UI. Only the alert creator and the admin user can edit the alerts.

1. In the application bar area, click the Alerts list and select Definitions.
2. In the Active Alerts tab, select an alert.
   The details section opens.

   Note: If the alert that you want to edit is paused, go to the Paused Alerts tab.
3. Click the Edit link.
   The Edit Alert window is displayed.
4. In the Alert Resource section, you can edit the following details:
   • Choose Select one or more target instances.
   • Include future instances Automatically apply the alert to future target instances. (This option is only available if all target instances are selected.)
   • For Instance(s) Select the resource instance.
     Note: The resource instances can be filtered based on certain criteria. For example, the disk type is displayed for RAID Pool Tier resource. You can filter the resource instances using the filter option (disk type) and then set alerts for the filtered resources. You can also choose to skip resource instances from the filtered list.
   • Include future instances Automatically include any future resource instances. (This option is only available if all resource instances are selected.)
5. In the Alert Condition section, you can set alert condition for the metric that was selected at the time of adding alert:
   • For configuration metrics, provide the following details:
     • Condition Select the condition type. Metrics with numeric values use: greater than, between, and less than. Metrics with string values use the having condition.
       Note:

       • Under certain circumstances, the Analyzer detail view cannot identify whether a metric is a numeric or string value. When this occurs, all condition types are listed in the GUI (greater than, between, less than, and having). To select the proper condition, you must know whether the metric is a numeric value or a string. You can find the value by running the query in Report Builder. See, Identifying the metric value.
       • If you are editing an alert with dynamic threshold, only the greater than and less than conditions are listed.
     • Threshold Depending on type of threshold (Static or Dynamic) defined when adding the alert, do the following:
       • Static threshold: Type or select a threshold value. (Certain metrics with string values include predefined thresholds.) The value set for the having condition is saved and is available for other users.

         The threshold value specified in this field applies to all the selected resource instances.

         Note:

         • The threshold field supports alphanumeric characters, hyphen (-), underscore (_) , comma (,), colon (:), at (@), slash (/), dot (.), and space.
         • Switching between static and dynamic thresholds is not supported.
         • Customize Threshold For Resources Click this link to customize the value for a specific resource instance.

           The Customize Threshold for Resources window is displayed. The instances selected in the Alert Resource section are displayed.

           1. Select the instances for which you want to customize the threshold. You can also filter the instances based on criteria, such as disk type.
           2. In the Set Custom Threshold field, enter a value and then click Update. The threshold value is updated for the selected instances.
           3. Click OK.
       • Dynamic threshold: The dynamic threshold is derived by adding the values of Daily Moving Average (DMA) and Standard Deviation (SD). Analyzer detail view uses last 7 days data to calculate the DMA and SD values. Based on DMA and SD values, the dynamic threshold is determined everyday when a day is changed (as per Analyzer detail view application time zone). You can select one of the following options:
         • 7 DMA + 1 SD
         • 7 DMA + 2 SD
         • 7 DMA + 3 SD

         SD is calculated by applying a formula. 1 SD is a value derived from the formula. 2 SD and 3 SD is the value of 1 SD multiplied by 2 and 3, respectively.

         Suppose, the DMA value is 20 and SD value is 10. The calculation will be as follows:

         • 7 DMA + 1 SD= 30
         • 7 DMA + 2 SD = 40
         • 7 DMA + 3 SD = 50
       Note:

       • Dynamic threshold cannot be edited using REST API.
       • Switching between static and dynamic thresholds is not supported.
   • For a performance metric, enter the following details:
     • Condition Select the condition type: greater than, between, and less than.
     • Threshold Depending on type of threshold (Static or Dynamic) defined when adding the alert, do the following:
       • Static threshold: Type the threshold value.
         The threshold value specified in this field applies to all the selected resource instances.

         Note: Switching between static and dynamic thresholds is not supported.
         • Customize Threshold For Resources Click this link to customize the value for a specific resource instance.

           The Customize Threshold for Resources window is displayed. The instances selected in the Alert Resource section are displayed.

           1. Select the instances for which you want to customize the threshold. You can also filter the instances based on criteria, such as disk type.
           2. In the Set Custom Threshold field, enter a value and then click Update. The threshold value is updated for the selected instances.
           3. Click OK.

         Note:

         • Dynamic threshold cannot be edited using REST API.
         • Switching between static and dynamic thresholds is not supported.
     • Criteria Select the criteria. (The maximum value for minutes is 60.)
       To select the proper alert criteria you must know the data collection interval of the metric, see Identifying the collection interval.

       Note:

       • If you want to add alerts for the metrics with a data collection interval exceeding 60 minutes, you must configure the data collection interval for these metrics up to 60 minutes on the RAID Agent.
       • The Criteria field is not applicable for the configuration metric. You can select criteria only for the performance metric.
     • Monitor Between Select the monitoring time. Alert monitoring window is based on UTC timezone. Be sure to select the appropriate time window. If applicable, also consider the Daylight Saving Time. For example, if the Analyzer detail view UI timezone is set to Pacific Time (GMT-08:00) and you want to add alert for time window 9:00 AM to 7:00 PM, then set alert monitoring window as 05:00 PM to 03:00 AM.
       Note: The Monitor Between field is not applicable for the configuration metric. You can select the monitoring time only for the performance metric.
6. In the Alert Notification section, click the Email, Syslog, or SNMP tab and provide the following details:
   • Email Select the email groups to which you want to send the notification, or type the individual email address. You can choose any of the following options:
     • Each alert violation Sends a notification on every alert.
     • Hourly or Daily Sends notification hourly or daily.
     • The first alert violation Sends the first violation alert and suppresses subsequent alert notifications when alert violations happen for an extended period. Sends the second notification when the alert condition is ended.
     Note: You can add email groups in Manage > Manage Email groups and the email address in Manage > Manage SMTP.

   • Syslog server Select the Syslog server.
     Note: You can configure the Syslog server in Manage > Manage Syslog.
   • SNMP Manager Select the SNMP Manager.
     Note:

     • You can configure the SNMP Manager in Manage > Manage SNMP.
     • If you select SNMP Manager, alert violations on the real-time data are not sent to the SNMP Manager.
7. Click Update.
