View Storage Resource Statistics in the Investigator

Use the following example procedure to review performance statistics in the Investigator for your storage data in table format or by creating side-by-side charts. Reviewing the information in side-by-side charts helps you identify trends.

Observe the following points about the Filter for TSF objects:

• The Filter in the Investigator for TSF objects is case-sensitive when you use some of the operators. For example, when you use the = (equal sign), less than - greater than (<> sign), and Like operators. Any test value that you enter in a filter where you use these operators for a TSF object must be in the same case as it is displayed. For storage TSF objects, field values are usually all upper case. For example, if a volume in TSF is shown as TSO123, it must be entered in the = (equal sign) operator filter query as TSO123 (all upper case) to find the match. Entering tso123 results in "no matches", as does any other entry that contains some lower case characters. In all non TSF storage objects (those objects not in the Statistics category), the Filter is not case-sensitive.
• Some TSF Storage Group objects may have spaces between the name and before its type (MVS, SMS, VAM, or USR) in the Storage Group Name field. When you use the Filter to search specifically for these names with spaces, use the Starts With or Contains operators with just the first or last part of the Storage Group Name (without the blanks). For example, to search for the DISK MVS storage group, use the following filter statement:

  Storage Group Name Starts With DISK 
  

  You can also use the % wildcard character which means any characters when placed between two words, if you are not sure if there are no spaces, one space, multiple spaces, or other characters between two words. For example, you could create the following filter statement:

  Storage Group Name Like DISK%MVS
  

  The Like operator means includes, so this filter would find all storage groups that have DISK, then followed with no characters or any characters, and then followed with MVS, anywhere in the Storage Group Name string.

Note: You can also display TSF object performance data in the Metrics panel.

Example: Monitor Storage Groups statistics charts in the Investigator

Your team monitors available space on storage groups so applications have enough space and to avoid space abends. Having sufficient space on storage groups improves the efficiency of your site. Retrieve a baseline of acceptable levels so you can compare current conditions against the baseline and measure performance.

Follow these steps:

1. Log in to CA Chorus.
2. Add the Investigator module to your dashboard from the Module Library, and click Start New Investigation.

   The Investigator opens.

3. Select Storage from the discipline drop-down list.
4. Expand the Statistics, Storage Groups subcategory, system, LPAR directory in the Storage object tree.

   Storage Group objects that have been set up to collect storage object metrics for TSF are displayed.

5. Select the Storage Group metrics object for which you want to view the metrics.

   The metrics object table opens.

6. Perform one of the following sequences:
   • To review the data using the Time Series Facility (TSF):
     1. Select the record in the table.
     2. Click Add Entity to Time Series in the Actions pane on the right-hand side.
     3. Select the Entity and Metrics for comparison, and click Perform Charting.
     4. Click the icon next to the Contributors button to duplicate the chart.
     5. Modify the End Date/Time or Period for each chart to compare a baseline view with a more current view.
   • To review all of the data in a tabular view while in the table view:
     1. Select the wrench icon.
     2. Add all of the Storage Group fields to the grid, and click Save.
     3. The Storage Group statistics appear in the table in the center pane.
     4. Click the export icon in the upper-right corner of the center pane.
     5. Save the table data to a comma-separated value (CSV) file.
7. Repeat these steps periodically and compare the data in TSF graphs or the CSV file. Keep the Storage Group statistics at acceptable levels.
