Local GOA Volume Group Attributes

Use the Local 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 Identifier 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 SystemThe MVS System Management Facility (SMF) identifier. Valid format is alphanumeric with a maximum of 4 characters; for example SP11.

Number of DatasetsThe total number of allocated datasets for the DB2 being monitored. Valid value is an integer in the range 0 - 10000.

Number of Extents The number of dataset extents that the operating system has allocated for a dataset. Valid value is an integer in the range 0 - 219.

Originating System Identifier Identifies the originating Candle Management Server (CMS). Valid format is alphanumeric, with a maximum of 32 characters; for example, DB2.USCACO01.D412.

Timestamp Represents the end of data collection or the end of an interval, and is the local time where the system is running. Valid format is
MM-DD-YY HH:MM:SS, where:

MM

Month

DD

Day

YY

Year

HH

Hour

MM

Minute

SS

Second

For example, 07-16-00 14:58:29 indicates that data collection ended on July 16, 2000 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 NameThe name of the volume that contains the DB2 objects. Valid format is alphanumeric, with a maximum of 6 characters; for example, PRI123.

Volume Service TimeThe 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 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 PercentThe 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 UtilizationThe 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.
