View Storage Object Performance Data in the Time Series Facility

The Time Series Facility (TSF) stores data that is collected and provided by CA products. TSF provides a single point for collection, storage, management, and organization of the product data. When you request a Time Series chart from the Investigator, TSF provides the data content for the chart.

The TSF displays storage statistics. That is, data from the objects in the Statistics folder in the object tree. When you add a storage object to TSF, it becomes an entity, and you can use it to create a chart. Doing so lets you determine trends and identify valid anomalies. The TSF charts allow up to four lines.

An entity is an application performance object that has been added to TSF. You can add the system entity to TSF with the CA Chorus for Storage Management discipline.

Note: For detailed common TSF concepts and procedures, see the CA Chorus Product Guide.

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

Example: Analyze storage group usage in the Investigator

In this example, the Storage Groups object is added to the TSF and the total space per group is analyzed. By monitoring the ratio between total storage capacity bytes, allocated bytes, and free bytes; you can evaluate the space usage compared to the free bytes.

The Storage Groups object provides a numeric description of space usage in each Storage Group. Each Storage Group is a collection of one or more volumes. They can be MVS esoteric names, DFSMS, CA Allocate, or storage engine system user-defined Storage Groups.

The Storage Group with the fixed name of TOTAL ONL displays totals for all volumes.

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.

    Select Storage from the discipline drop-down list.

  3. Expand the Statistics, Storage Groups subcategory, system, LPAR directory in the Storage object tree.

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

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

    The metrics object table opens.

  5. Select the record in the table.
  6. Click Add Entity to Time Series in the Actions pane on the right-hand side.

    The system is added to the TSF and the TSF panel appears.

  7. Select the Entity and Metrics, and click Perform Charting.

    TSF produces a chart for the selected metric. The selected entity becomes a line on the chart.

  8. Select an entity from the Contributors drop-down list and click Contributors.

    The Entities panel becomes the Base Entities panel and shows the original criteria that is passed by the Investigator for the selected entity.

  9. Click the Contributors drop-down list.

    The drop-down list shows the valid contributors.

    Note: To exit the contributors function, click Back to Entities.

  10. Select a contributor type.

    A list of all the contributors for the selected entity and metric combination appears. If no contributors appear, then clear one or more base entities.

    Note: All Storage metrics are defined as “averages”. When multiple values are rolled up for a time period, or across multiple entities, the average value is represented on the Time Series charts.

  11. Click Perform Charting.

    The new chart is generated from the selected entities.

    The chart provides an overview of storage group attributes and allows you to easily see historical and current attribute values to evaluate the space usage compared to the free bytes.
