DB2 Volume Activity Attributes

Use the DB2 Volume Activity attributes to create situations to monitor the status and performance of DB2 volume activity.

Data Sharing Group The name of a data sharing group. It is an alphanumeric text string, with a maximum length of eight characters.

DB2 IO Percent The percentage of DB2 I/O activity to the volume. Valid entry ranges from 0.0 to 100.0.

DB2 ID The name of the DB2 subsystem. It is an alphanumeric text string, with a maximum length of four characters.

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

Filler A placeholder to keep fullword alignment.

IDNAME An internal attribute used for navigation, it contains either the data sharing group name or the DB2ID. It is an alphanumeric text string, with a maximum length of eight characters.

MVS System The MVS System Management Facility (SMF) ID. It is an alphanumeric text string, with a maximum length of four characters.

Number of Data Sets The total number of allocated data sets for the DB2 subsystem being monitored.

Number of DB2 systems The total number of monitored DB2 systems that are sharing this volume.

Number of Extents The number of extents the operating system has allocated for a data set.

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 The date and time, as set on the monitored system, indicating the instance when the agent collects information.

Volume DB2 IO The total number of I/Os for this volume originating from the DB2 system being monitored.

Volume DB2 IO Rate The total number of I/Os per second for the volume originating from the DB2 subsystem being monitored.

Volume DB2 IO Rate MAX The maximum I/O rate per second during the collection period.

Volume Name The name of the volume that contains the DB2 objects. It is an alphanumeric text string, with a maximum length of six characters.

Volume Service Time The average service time for the volume since the beginning of the collection interval.

Volume Service Time MAX The maximum service time for the volume since the beginning of the collection interval.

Volume Total IO The total number of I/Os for this volume.

Volume Total IO Rate The total number of I/Os per second for the volume.

Volume Use Percent The percentage of DB2 I/O activity to the volume that is attributable to the database, computed by dividing the total I/O rate for the database by the total DB2 I/O rate to the volume. Valid entry ranges from 0.0 to 100.0.

Volume Utilization The percentage of volume utilization, which represents the percent of time the volume is in use. Valid entry ranges from 0.0 to 100.0.
