Display Monitor History

The monitor history is a record of all the instances that you invoked for a particular monitor profile. To see the history of a monitor profile from the Monitor Definition panel, enter line command H (History) next to the profile and press Enter.

The Monitor History panel is displayed. This panel lists all data sets for the selected monitor profile.

For more information about the collected data, see Samples and Observations, and Sampling Rules .

Press PF11 to scroll right and see more fields.

The fields on the Monitor History panel are described next:

Measured Job

Name of the job being measured by CA Mainframe Application Tuner.

Run

Number of active runs for this profile.

Start Date

Date this monitor instance was run.

CPU Time

Length of time this monitor session ran in HH:MM:SS format.

EXCP Count

Number of input/output operations for the job step during the monitored period.

This number includes I/O counts that are not reflected in the I/O counts at the DD name level.

SIO Rate

Number of start I/O operations per second for the job during the monitored period.

Percent Active

Percentage of the monitored period during which one or more CPUs were in use by application tasks within the address space.

This number is the ratio of samples with CPU active to the total number of samples.

Percent Wait

Percentage of the monitored period during which application tasks within the address space were not using CPU.

This number is the ratio of samples with CPU not active to the total number of samples.

Percent NonDisp

Percentage of samples where CA Mainframe Application Tuner detected the address space to be dispatchable but not dispatched.

This number is the ratio of samples in which the address space was dispatchable but not dispatched to the total number of samples.

Percent ProcDelay

Percentage of the monitored period when CA Mainframe Application Tuner detected the address space was unable to be dispatched because a processor could not be made available.

While this situation is occurring, the application is unable to execute.

Percent Swapped

Sample SWAPPED percentage.

This number is the ratio of samples when the job was swapped out to the total number of samples.

Observation Rate

Final observation rate, which is the number of observations per millisecond, calculated by CA Mainframe Application Tuner.

CA Mainframe Application Tuner might have adjusted this rate during the monitor.

For information about monitoring the entire duration of a job step, see Determine Number of Observations to Take and Total Time to Monitor.

Samples Collected

Number of samples collected during the monitored period.

A significant difference between samples collected and samples used might be noted during step-level monitoring.

Samples Used

Number of samples used in the last analysis request.

Elapsed Time

Length of time the monitor session ran in HH:MM:SS format.

Measured Job ID

JES job identifier of the job that was monitored.

This field is valid for jobs that were initiated under a job entry subsystem.

Measured Step

Name of the job step that was monitored.

Measured ProcStep

Name of the job step within a cataloged procedure that was monitored.

Measured Program

Name of the program on the EXEC statement of the JCL of the job that was monitored.

Measured ASID

Address space identifier of the job that was monitored.

System

Name of system where job was monitored.

SMF ID

One- to four-character name assigned with the system.

The SMFID is written as a field in any SMF record created by this system.

Exists

Indicator of data set availability.

You can display the following values in this field:

• YES - The data set containing the sample data for the monitor instance is available and has not been migrated.
• NO - The data set is not found.
• ML1 - The data set containing the sample data for the monitor instance exists but is migrated to the DFSMShsm ML1 migration pool. ML1 migration generally goes to disk.
• ML2 - The data set containing the sample data for the monitor instance exists but is migrated to the DFSMShsm ML2 migration pool. ML2 migration generally goes to tape.
• INV - The data set name is invalid. If this value is displayed, check the entry to make sure the data set name is valid before continuing.
• PER - A program error occurred. This value can indicate a catalog error other than the data set not being found. See your technical support staff for more information.

Dataset name

Data set name of the monitor data set.

Invocation Time

Date this sample monitor was invoked.

Invocation Date

Time this sample monitor was invoked.

Requested Observations

Number of observations requested in the monitor definition.

Error samples

Number of samples that contain errors.

The samples are not included in the monitor data set.

Storage Above

High-water amount of virtual storage above the 16MB line that is used by the job.

Storage Below

High-water amount of virtual storage below the 16MB line that is used by the job.

Page in Count

Number of page-in operations for the job.

A high value in this field can indicate job delays.

z/OS level

Release level of the operating system where the target job was executed.

CPU type

CPU type of the system on which this monitor instance executed.

CPU Mdl

CPU model number of the system on which this monitor instance executed.

CPU Serial

CPU serial number of the system on which this monitor instance executed.

The following table lists the Monitor History panel line commands and describes where to find more information about each command.

If the monitor request has not been completed, or has been abnormally terminated, these fields might appear as BLANK, ZERO, or NA. The fields will be populated the first time you analyze the monitor.
