The monitor history is a record of all the instances that you invoked for a particular monitor profile. Use the following procedure to see the history of a monitor profile from the Monitor Definition panel.
Follow these steps:
The Monitor History panel is displayed. This panel lists all data sets for the selected monitor profile.
Note: For more information about the collected data, see Samples and Observations, and Sampling Rules.

The fields on the Monitor History panel are described next:
Indicates the name of the job measured by CA MAT.
Indicates the sequence of monitor runs. If five monitor runs were scheduled for a single job step execution, the first run is Run Number.
Indicates the date this monitor session began.
Indicates the length of time the monitor session ran (HH:MM:SS).
Number of input and 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.
Indicates the number of start I/O operations per second for the job during the monitored period.
Indicates the percentage of active samples. This number is the ratio of samples with CPU active to the total number of samples.
Indicates the sample WAIT percentage. This number is the ratio of samples with CPU not active to the total number of samples.
Indicates the ratio of samples when the job was ready to run but was prevented from running because of higher priority work in the system to the total number of samples.
Percentage of the monitored period when CA MAT 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.
Sample SWAPPED percentage.
This number is the ratio of samples when the job was swapped out to the total number of samples.
Final observation rate, which is the number of observations per millisecond, calculated by CA MAT.
CA MAT 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.
Number of samples collected during the monitored period.
A significant difference between samples collected and samples used might be noted during step-level monitoring.
Number of samples used in the last analysis request.
Length of time the monitor session ran in HH:MM:SS format.
JES job identifier of the job that was monitored.
This field is valid for jobs that were initiated under a job entry subsystem.
Displays the name of the job step that was monitored.
Displays the name of the job step within a cataloged procedure that was monitored.
Displays the name of the program on the EXEC statement of the JCL of the job that was monitored.
Displays the address space identifier of the job that was monitored.
Displays the name of system where job was monitored.
Displays the one- to four-character name assigned with the system.
The SMFID is written as a field in any SMF record created by this system.
Displays the indicator of data set availability.
You can display the following values in this field:
Indicates that the data set containing the sample data for the monitor instance is available and has not been migrated.
Indicates that the data set is not found.
Indicates that 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.
Indicates that 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.
Indicates that the data set name is invalid. If this value is displayed, verify the validity of the data set name before continuing.
Indicates that a program error occurred. This value can indicate a catalog error other than the data set not being found. For more information, contact your technical support staff.
Displays the data set name of the monitor data set.
Displays the date this sample monitor was invoked.
Displays the time this sample monitor was invoked.
Displays the number of observations requested in the monitor definition.
Displays the number of samples that contain errors.
The samples are not included in the monitor data set.
Displays the high-water amount of virtual storage above the 16-MB line that is used by the job.
Displays the high-water amount of virtual storage below the 16-MB line that is used by the job.
Displays the number of page-in operations for the job.
A high value in this field can indicate job delays.
Displays the release level of the operating system where the target job was executed.
Displays the CPU type of the system on which this monitor instance executed.
Displays the CPU model number of the system on which this monitor instance executed.
Displays the CPU serial number of the system on which this monitor instance executed.
This section lists the Monitor History panel line commands and describes where to find more information about each command.
Displays information that is not directly related to the target application is eliminated. Data is reported as follows:
The following samples are eliminated from analysis: Non-dispatched (.NONDISP), No CPU available (.DISPWT), Processor Delay (.PROCDLY), Page wait (.PAGEWT), Swapped (.SWAPWT), and No activity (.OTHERWT). These samples are considered for the overall OverView activity percentages and runtimes.
CodeView and related histograms are sorted based on Active percentages, not total percentages. The Visual field reflects the Active percent only. Wait samples are included. Percentages are calculated on total samples; all activity values have equal weight.
Allows you to analyze information and calculate the percentages based on samples where the program was actively using CPU. Samples that contain only wait information are filtered out, which allows you to make normalized CPU comparisons of program activity.
Allows you to compare delays occurring when the program is executing in both active and wait states.
Percentages are calculated based on all samples.
Allows you to analyze information and calculate percentages based on samples where the program was in a wait state. Samples that contain only active information are filtered out which allows you to make normalized comparisons of program wait activity.
Removes the monitor definition and the monitor’s history but does not delete the associated monitor data sets.
Note: For more information, see Delete a Monitor Definition.
Lets you generate batch reports any time after you invoke the monitor and data collection has been completed.
Note: For more information, see Submit a Job to Generate Batch Reports.
Accesses the CSV Reporting panel that allows you to submit a batch job to create comma-separated value output of analysis reports for the selected profile. These reports can be imported for use with the Spreadsheet Converter.
Note: For more information, see Create Spreadsheet Reports.
Creates an export file of the monitor data set suitable for electronic transmission. Use this command when sending monitor data to CA Technical Support.
Displays the batch reports job card that is associated with the selected Monitor profile.
If the monitor request has not been completed, or has been abnormally terminated, these fields might appear as BLANK, ZERO, or NA. The fields are populated the first time you analyze the monitor.
