MAT Detect Plug-in for Zowe CLI

The MAT Detect plug-in for Zowe CLI enables you to detect performance issues and access performance data supplied by the Performance Management Assistant component (PMA) of Mainframe Application Tuner. The plug-in ensures interaction of your jobs with the Performance Management Assistant and provides access to PMA functionality.

If you include the MAT Detect plug-in for Zowe CLI in your CI/CD pipeline, the PMA module can measure the performance of your job after each code commit and evaluate the performance based on the previous measurements and the thresholds that you define within PMA. This information can help you detect possible performance degradation of your job at early testing stages, before your code is deployed to the production environment.

Create a User Profile

To use the MAT Detect plug-in for Zowe CLI, create the following profiles:

• z/OSMF profile
• PMA profile

The profile details are stored in the Zowe configuration file. To create a global Zowe configuration file, use the command zowe config init --global-config, then edit the configuration file and add sections that are specific to the required profiles.

Create a z/OSMF Profile

To interact with z/OS jobs, you need to define a z/OSMF profile. The profile contains your host, port, username, and password for z/OSMF. Edit the Zowe global configuration file and add a section with the z/OSMF profile details:

"zosmf": {
            "type": "zosmf",
            "properties": {
                "port": 443,
                "host": "zosmf.example.com",
                "user": "johndoe",
                "password": "qwerty"
            },
            "secure": []
        },

Create a PMA Profile

To enable the interaction of the MAT Detect plug-in for Zowe CLI with PMA, you need to create a PMA profile. Edit the Zowe global configuration file and add a section with the PMA profile details:

"pma": {
            "type": "pma",
            "properties": {
                "job_acct": "123456789",
                "job_class": "A",
                "job_mclass" "A",
                "job_load": "PMA.MAT12.CEETLOAD",
                "job_pmahlq": "PMA.MAT12"
            },
            "secure": []
        },

PMA Profile Options
--job_acct | --ja (string)
Specifies z/OS TSO/E accounting information. Only numbers are allowed.

--job_class | --jc (string)
Your z/OS class information. Valid values are any characters from A to Z and any numbers from 0 to 9.

--job_mclass | --jmc (string)
Specifies the MSGCLASS parameter value and assigns the job log to the specified output class. The specified MSGCLASS value is used in all JCLs that PMA runs while you execute the commands. If you do not provide the job_mclass parameter, the default MSGCLASS value is used. Values: alphanumeric characters (A-Z, 0-9).
Default value: A

--job_load | --jl (string)
Specifies PMA loadlib information. To provide the correct loadlib name, refer to your PMA installation details (&HLQ.CEETLOAD).

--job_pmahlq | --jph (string)
Specifies the PMA HLQ to access the KSDSALT, KSDSJOB, and KSDSEXC vsam files that ensure the collection of the necessary data.

If the details are not specified or if you want to temporarily use different profile settings, you can specify all or some profile details with each command. The profile details that are provided with a command have the highest priority and override all other values. For more information about using profiles in Zowe, see Using Global Profile Configuration in the Zowe documentation.

Use Cases and Commands

The MAT Detect plug-in for Zowe CLI commands are organized in the following command groups:

GET

The commands from the GET group enable you to get performance information using PMA utilities. You can get the current performance data of your jobs and check for today's performance alerts.

get | gt

Usage

$ zowe mat-pma-util get <command>

where command is one of the commands described below.

perf | pf

Gets the current performance data of a specific job using PMA. If the current measurement results for any of the measured parameters are higher than the averages, an alert message is displayed.

Usage

$ zowe mat-pma-util get perf <jobname> [options]

jobname (string)
The name of the job you are interested in or under test (e.g. TESTPMA8).

Options
The PMA Connection and Profile Options are available for this command.

$ zowe mat-pma-util get perf TESTPMA8

• Get the current performance data of the TESTPMA8 job using specific PMA profile details:

$ zowe mat-pma-util get perf TESTPMA8 --ja 123456789 --jc A --jmc A --jl HLQ.CEETLOAD --jph PMAHLQ

alert | at

Check for alerts created in PMA and detect whether any of your jobs violates statistical norms of today’s performance. If the threshold is exceeded, a PMA alert is triggered.
