Use the Local Group Object Analysis (GOA) Volume Group attributes to create situations that monitor DASD performance by volume.
Data Sharing Group The name of a data sharing group. Valid format is alphanumeric, with a maximum of 8 characters; for example, TDDB241G.
DB2 ID The name of a DB2 subsystem.
IDNAME An internal attribute used for navigation, it contains either the Data Sharing Group Name or the DB2ID. Valid format is alphanumeric with a maximum of 8 characters; for example TDDB242G.
MVS System The MVS System Management Facility (SMF) ID. Valid format is alphanumeric with a maximum of 4 characters; for example SP11.
Number of Data Sets The total number of allocated data sets for the DB2 being monitored. Valid value is an integer in the range 0 - 10000.
Number of Extents The number of data set extents that the operating system has allocated for a data set. Valid value is an integer in the range 0 - 219.
Originating System ID Identifies the originating Tivoli Enterprise Monitoring Server. Valid format is alphanumeric, with a maximum of 32 characters; for example, DB2.USCACO01.D412.
Time Stamp Represents the end of data collection or the end of an interval, and is the local time where the system is running.
For example, 07-16-10 14:58:29 indicates that data collection ended on July 16, 2010 at 14:58:29 PM.
Volume DB2 I/O The total number of I/Os for the volume originating from the DB2 subsystem being monitored. Valid value is an integer in the range 0 - 2147483647.
Volume DB2 I/O Rate The total number of I/Os per second for the volume originating from the DB2 subsystem being monitored. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 9999.9; for example, 0.9.
Volume Name The name of the volume that contains the DB2 objects. Valid format is alphanumeric, with a maximum of 6 characters; for example, PRI123.
Volume Service Time The average service time for the volume since the beginning of the collection interval. This value is the sum of the average I/Os pending time, the average I/Os connect time, and the average I/Os disconnected time for the volume. It does not include I/Os queue time. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 9999.9; for example, 1.7.
Volume Total I/O The total number of I/Os for the volume. The value is from an MVS perspective. If the volume is shared by multiple MVS systems, the value may not reflect all I/O activity for the volume. Valid value is an integer in the range 0 - 2147483647; for example, 19.
Volume Total I/O Rate The total number of I/Os per second for the volume. The value is from an MVS perspective. If the volume is shared by multiple MVS systems, the value may not reflect all I/O activity for the volume. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 9999.9; for example, 1.7.
Volume Use Percent The percentage of DB2 I/O activity to the volume. The program calculates the value by dividing the total I/O rate for the database by the total I//O rate for the volume. Valid format is a decimal number, with one decimal place allowed, in the range 0.0 - 100.0; for example, 3.0.
Volume Utilization The percentage of volume utilization. The value represents a percentage of time the volume is in use. Valid value is an integer in the range 0 - 100; for example, 22.
