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. Valid entry 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. Valid entry 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. Valid entry is an integer of up to four digits.

Filler A placeholder to keep fullword alignment. Valid entry is an integer of up to two digits.

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

MVS System The MVS System Management Facility (SMF) ID. Valid entry 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. Valid entry is an integer of up to four digits.

Number of DB2 systems The total number of monitored DB2 systems that are sharing this volume. Valid entry is an integer of up to four digits.

Number of Extents The number of extents the operating system has allocated for a data set. Valid entry is an integer of up to four digits.

Origin Node Name The name of the DB2 system. Valid entry is an alphanumeric text string, with a maximum length of 32 characters.

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

The timestamp format for SCAN and STR functions is CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:
  • C = Century (0 for 20th, 1 for 21st)
  • Y = Year
  • M = Month
  • D = Day
  • H = Hour
  • M = Minute
  • S = Second
  • m = millisecond

Volume DB2 IO The total number of I/Os for this volume originating from the DB2 system being monitored. Valid entry is an integer of up to four digits.

Volume DB2 IO Rate The total number of I/Os per second for the volume originating from the DB2 subsystem being monitored. Valid entry is an integer of up to four digits.

Volume DB2 IO Rate MAX The maximum I/O rate per second during the collection period. Valid entry is an integer of up to four digits.

Volume Name The name of the volume that contains the DB2 objects. Valid entry 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. Valid entry is an integer of up to four digits.

Volume Service Time MAX The maximum service time for the volume since the beginning of the collection interval. Valid entry is an integer of up to four digits.

Volume Total IO The total number of I/Os for this volume. Valid entry is an integer of up to four digits.

Volume Total IO Rate The total number of I/Os per second for the volume. Valid entry is an integer of up to four digits.

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.
