Group Object Analysis Volume Summary Attributes

Use the Group Object Analysis (GOA) Volume Summary attributes to create situations that monitor DASD performance by volume.

Data Sharing Group The name of a data sharing group.

It is an alphanumeric text string, with a maximum of 8 characters; for example, TDDB241G.

DB2 ID The name of a DB2 subsystem.

DB2 I/O Percent The percentage of total DB2 I/O that is attributable to the volume. It is calculated by dividing the volume DB2 I/O count by the total DB2 I/O count. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 100.0; for example, 24.

Extents per Data Set Ratio The ratio of total extents allocated to the total data set count.

IDNAME An internal attribute used for navigation, it contains either the Data Sharing Group Name or the DB2ID.

MVS System The MVS System Management Facility (SMF) ID. It is an alphanumeric text string 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 DB2 systems The total number of monitored DB2 systems. Valid value is an integer in the range 1 - 64.

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 The managed system name of the agent. It is an alphanumeric text string, with a maximum of 32 characters; for example, DB91:SYS1:DB2.

Time Stamp Represents the end of data collection or the end of an interval, and is the local time where the system is running.

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 DB2 I/O Rate Max The maximum I/O rate per second during the collection interval. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 2147483647.0; for example, 2.5.

Volume Name The name of the volume that contains the DB2 objects. It is an alphanumeric text string, 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 IOS pending time, the average IOS connect time, and the average IOS disconnected time for the volume. It does not include IOS 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 Service Time Max The maximum service time for the volume since the beginning of the collection interval. The value is the sum of the IOS pending time, the IOS connect time, and the IOS disconnect time for the volume. It does not include IOS queue time. Valid value is a decimal number, with one decimal place allowed, in the range 0.0 - 9999.9; for example, 0.5.

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 and represents the percentage of time the volume is in use. Valid value is an integer in the range 0 - 100; for example, 22.
