Channel Initiator Tasks attributes

This channel initiator statistics attribute group provides channel initiator task data from SMF Type 115 records for all tasks per task type.

Average CPU Microseconds The average task busy CPU time per request in microseconds. The valid format is a 64-bit integer.

Average Elapsed Microseconds The average task elapsed time per request in microseconds. The valid format is a 64-bit integer.

CPU Busy Percent The task busy CPU time percent of the sample interval duration. The valid format is decimal (formatted to 1 decimal place).

Elapsed Percent The task elapsed time percent of the sample interval duration. The valid format is decimal (formatted to 1 decimal place).

Channels The number of channels running in a dispatcher task. This value is n/a for other types of tasks, which is denoted by a value of -1 enumerated to n/a. The valid format is an integer.

CPU Busy Microseconds The task busy CPU time in microseconds in the sample interval. The valid format is a 64-bit integer.

Elapsed Microseconds The task elapsed time in microseconds in the sample interval. The valid format is a 64-bit integer.

Host Name The name of the system on which this queue manager is running. On z/OS systems, this is the SMF ID. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Interval Time The length of the sample interval, expressed in hundredths of seconds. The valid format is decimal (formatted to 2 decimal places).

Longest Request Microseconds The duration of the longest request for SSL and DNS task types. This value is n/a for other types of tasks, which is denoted by a value of =1 enumerated to n/a. The valid format is a 64-bit integer.

Longest Request Date & Time The date and time of the longest request for SSL and DNS task types. This value is n/a for other types of tasks, which is denoted by a value of 16 character zeroes enumerated to n/a. The valid format is the standard 16-character date/time format CYYMMDDHHMMSSmmm, where the strings have the following meanings:
C Century (0 for 20th, 1 for 21st)
YY Year
MM Month
DD Day
HH Hour
MM Minute
SS Second
mmm Millisecond

Origin Node The IBM MQ Monitoring agent-assigned name of the node on which the data for the queue manager originates. On z/OS systems, this name takes the form qmgr:smfid:MQESA, where qmgr is the name of the queue manager and smfid is the z/OS system ID or SMF ID.

QMgr Name The name that is assigned to this queue manager. The valid format is an alphanumeric string of up to 48 case-sensitive characters.

Query Type Indicates whether the query addresses current, recent or historical data samples; the default is current, which is the required setting for situations for this table. Valid values are as follows:
Current=0
Recent=1
Historical=2

Request Count The number of requests for the task in the sample interval. The valid format is an integer.

Sample Date & Time The date and time of the sample. The valid format is the standard 16-character date/time format CYYMMDDHHMMSSmmm, where the strings have the following meanings:
C Century (0 for 20th, 1 for 21st)
YY Year
MM Month
DD Day
HH Hour
MM Minute
SS Second
mmm Millisecond

Task Control Block Address The Task Control Block (TCB) address for the task in the Channel Initiator address space. The valid format is an 8 byte string of hexadecimal characters.

Task Number The number assigned to the task, 0 - N. The valid format is an integer, maximum four digits.

Task Type The type of channel initiator task. Valid task types:
  • Dispatcher=DSP
  • Adapter=ADP
  • SSL=SSL
  • DNS=DNS

Wait Microseconds The task wait time in microseconds in the sample interval. The valid format is a 64-bit integer.

Wait Percent The task wait time percent of the sample interval duration. The valid format is decimal (formatted to 1 decimal place).
