Viewing Storage Object Performance Data in the Investigator › Alerts for Storage Conditions

Alerts for Storage Conditions

An alert is a text- and visual-based indicator of abnormal behavior on your logical partitions (LPARs). The Alerts module lets you monitor and investigate alerts from the dashboard as they are generated. When a defined processing limit is reached or exceeded on an LPAR, an alert is issued.

To view alerts in the Alert module, add it to your CA Chorus dashboard and follow the prompts to configure it.

Alerts can be generated two ways:

• Alerts generated by the CA Chorus Policies module.
• Alerts generated by the General Object Automation (GOA) component of the storage engine system.

Policies Module Alerts

Use the Policy Status Light module to create simple policy alerts. These types of Alerts are better suited for when one field in an object row meets a certain condition of which you want to be notified of.

Example set up of idle data sets Policy Light and Alert

As a storage administrator you want to be alerted of any online data sets that have not been used for a lengthy period of time so you can move them to cheaper storage media. Data sets that have not been used for a long period of time waste online space. This example explains how to set up a Policy Light and an alert when more than 10 online data sets have not been used for more than 365 days. Change values in the example to meet your site specific storage management policy

Follow these steps:

1. Log in to CA Chorus.
2. Add the Policy Status Light module to your dashboard.
3. Configure the Policy Status Light module.
4. Select Storage from the discipline drop-down list and then select Chorus Personal Policies.
5. Click Create New Policy in the Actions pane.

   The Details pane expands with the General Details tab selected.

6. Enter Idle Data Sets GT 365 days in the Name field and in the Description field enter Number of data sets that have been unused for at least 365 days, select Public, and click Next.

   The Objects tab is selected in the Details pane.

7. Click Next and then Modify to open the Object Picker window and the Storage tree.
8. Expand the Storage tree to the directory Diagnostics & Investigations, Data Set Management, and Summaries.
9. Select the object Archive Data Set Modeling to open it.

   This object is an archive modeling table. It lists the number of data sets and the space that would be archived if you adopted an archive policy based upon the value in the Days Unused field.

   Note: This object provides a list of unused data sets in increments of days. In this example we use 365 days, but you can choose the unused days row that best meets your site's storage policy.

10. Scroll down the table and select the check-box in the row with 365 in the Days Unused column.
11. Click the Select button in the menu bar.

    The line item is added to the Objects tab in the Details pane of the Object Picker.

12. Click Next to open the Rules tab in the Details pane.
13. Click the down-arrow in the Parameter field and select Number of Dsn (number of data sets).
14. Click the down-arrow in the Threshold field and the > (greater-than) operator, enter 10 in the value field, and click Next.

    Note: Enter a value that best meets your site's storage policy.

    The Actions tab opens in the Details pane.

15. Do the following:
    • Select Change Traffic Light Color and Red.
    • Select Send Alerts to Alerts Module and click Configure (it displays when you select Send Alerts to Alerts Module). In the Alert Details dialog select Severity 1 from the Severity drop-down list and enter the message Number of data sets that are idle for more than 365 days exceeds 10 and click Save.
    • In the Action Management section enter 1 in the Count of Events field and 24:00:00 in the Duration field.
    • In the Action Suppression section enter 24:00:00 in the Suppression Duration field.
16. Click Finish to add the Policy to the Chorus Personal Policies object.

    Note: You can select the policy in the object and select the Edit icon in the Details pane to make changes to the policy.

17. Select the check-box next to the policy and click Save to close the Object Picker window.

    The Edit Title/Add Description dialog opens where you can change the name and enter the description Investigate data sets that are idle for more than 365 days.

18. Click Save.

    The Policy Light is added to the dashboard. If the light is green, the number of data sets that have been idle for 365 days or more is equal-to or less-than 10. If the light is red, the number of data sets that have been idle for 365 days or more is greater-than 10.

19. Add the Alerts module to your dashboard, and follow the prompts to configure it.
20. Select Chorus Alerts in the Alert Source field and Idle Data Sets Alerts in the Module Label field.

    When the Policy Light is red, the related Alert appears in the Alerts module labeled Idle Data Sets.

    You have created a light policy and CA Chorus Alerts appear when the conditions defined are met.
