Overview of attributes

OMEGAMON for Storage gathers data from remote agents located on the managed systems of your network and stores this data in system elements called attributes. You can use these attributes to build situations to monitor the performance of the managed systems you are concerned with.

Attributes correspond to the column names contained on the table views in associated OMEGAMON for Storage on z/OS workspaces. Related attributes are grouped into attribute groups. A given table view contains information provided by a single attribute group.

To use attributes effectively, you must first understand the structure of an attribute.
  • An attribute is made up of an attribute group and an attribute item.
  • An attribute group associates attributes that refer to some unique characteristic of the data that is being stored.
  • An attribute item stores data for a particular property of an attribute group.

    For example, in the attribute TOTALSTORAGE_RANKS.Total_Bytes_Read

  • Total Bytes Read is an attribute item that stores a value representing the total number of bytes read from the rank over the interval in the following attribute group.

You use attributes to create situations that monitor the state of your storage environment. A situation describes a condition you want to test. When you start a situation, the monitoring server compares the values that you have assigned for the situation's attributes with the values collected by OMEGAMON for Storage on z/OS and registers a situation event if the condition is met. You are alerted to situation events by indicator icons that appear in the Navigator.

Attributes are listed and described in the online help for OMEGAMON for Storage on z/OS
