The All Storage Solutions category folder contains all the Summary Objects available in the storage object tree. They are divided into two sub folder categories:
Contains Summary Objects supplied with the storage engine from the factory.
Contains Summary Objects that you have created. Use the Summary Designer in the storage engine windows client to create your own Summary Objects.
In a multiple storage engine environment, user-defined Summary Objects that exist in the Main Engine at the time of the JBoss server startup are included in the storage object tree. Use the Summary Objects Distribution Wizard in the storage engine windows client to distribute user-defined Summary Objects to your storage engines. If you create new Summary Objects after the JBoss server startup, you must restart the JBoss server to display them in the Investigator.
Note: For more information about starting and stopping the JBoss server, see the CA Chorus Administration Guide. For more information about the Summary Designer and the Summary Objects Distribution Wizard in the storage engine windows client, see the CA Vantage User Guide. Both guides are available in the Knowledge Center.
Summary Objects summarize the data present in any Source Object. For example, you want to know how many items match certain filter criteria, the average value of certain fields, or the maximum and minimum values applicable to a field. Each row in a Summary Object provides statistics on a Summary Group. A Summary Group is simply a subset of the Source Object data that you define using a method. The statistics available include counts, maximum values, minimum values, average values, and totals. These statistics are provided for each Summary Group and for all the records in the object table.
Summary Objects have an object name, an entry on the Object tree and behave the same way as all other objects. Summary Objects can take advantage of all storage engine services such as report distribution, historical logging, trending, and automation. These services let you distribute reports, generate alerts, take automated actions, and identify trends, which are all based on the summarized statistical information present in Summary objects.
The following methods are available to define the Summary Groups within an object:
This method defines Summary Groups that are based on the value of up to five fields that combine to produce a key. All records that have the same values in this key make up a Summary Group and are summarized in a single Summary Object row. A separate row is produced for every change or break in the value of the key. A single Summary Object row is included that provides overall statistics for the entire Summary Object.
An example of the Value Method is to summarize DASD volumes by the vendor field. In this example, there would be one Summary Group for each vendor (for example, IBM, EMC, HDS, and StorageTek) with selected statistics calculated for each vendor's share of the DASD volumes. The Value Method also provides overall statistics for the entire list of DASD volumes.
This method defines Summary Groups that are based on a numeric field and a step size. A single Summary Object row is produced for all the rows that fall into each Summary Group that is established by the field name and step size. A single Summary Object row is included, that provides overall statistics for the entire Summary Object.
An example of the Step Method is to summarize data sets by the block size field, with a step size of 4096. In this example, there would be one Summary Group for all data sets having block sizes from 0 to 4095, from 4096 to 8191, from 8192 to 12287, and so on. The selected statistics are calculated for the data sets having block sizes that fall into these ranges. Overall statistics for the entire list of data sets are provided.
In this method, the content of each Summary Group is determined by a complete filter expression. Up to 1000 filters are allowed. All records that match each filter make up a Summary Group and are summarized in a single Summary Object row. If any records do not match any of your filters, the summary of those records is given a Summary Group name of UNASSIGNED and is displayed on a separate row. A grand total for all of the records (including UNASSIGNED) is displayed in the ALL RECORDS row. The Unassigned row, All Records row, or both can be turned off so that they do not appear in the table.
An example of the Filter Method is to summarize tape volumes by megabytes used. Where one filter is set for all tape volumes using less than 50 MB and another filter for tape volumes using more than 50 MB.
This method is similar to the Value method. But instead of using the entire value of a field to define the contents of a Summary Group, only a portion of a field value is used. The "." and "/" characters are used as delimiters. Each node is separated by a delimiter. The common example of a Node field is the data set name or directory name. A Summary Object Row is produced for all the rows that have the same values in the specified nodes.
For example, a data set name summarized by node 1 identifies all the unique high-level qualifiers being used, and produces a Summary Object row for each of them. A subtotal or summary line is produced for all the rows that have the same values in the specified nodes.
Note: For more information about Summary Objects, see the CA Vantage User Guide. This guide is available in the Knowledge Center.
The CA SRM category displays the CA SRM open systems objects. These objects provide an overview of your open systems storage environment. These objects are available if you have licensed CA SRM and configured the storage engine to display them.
Note: For more information about CA SRM object configuration, see the CA Vantage Configuration Guide.
The objects represent your open systems storage:
