Tivoli Event Pump for z/OS V4.2.2 Overview

Overview

The IBM® Tivoli® Event Pump for z/OS® product has been focused on including "as-is" best practices for customers to manage their subsystems and enterprise applications. Continuing with this focus, the newly released Tivoli Event Pump for z/OS V4.2.2 product significantly extends your message management capability by including the following features:

New source for messages

The Event Pump now supports JES SPOOL SYSOUT(JOBLOG) message processing. The product can now handle not only z/OS system console (SYSLOG) messages, but also JOBLOG messages. This new functionality is called JOBLOG Data Source.

New event feeds

Some of the following new event feeds are also available as interim fixes in V4.2.1:

  • SMS event feed
  • IBM Tivoli AF/OPERATOR on z/OS event feed
  • Set of BMC MainView event feeds:
    • MainView for z/OS
    • MainView for IBM CICS®
    • MainView for IBM DB2®
    • MainView AutoOPERATOR for z/OS

Easy-to-use improvements

To simplify configuration efforts for new users (and also gain performance benefits), two of three address spaces that are required to run the Event Pump product have been combined.

Debug and Trace Facilities

In this release, the built-in trace and debug facilities have been significantly enhanced to make problem analysis easier and faster.

Tivoli Event Pump for z/OS V4.2.2: New event feeds

Before introducing the JOBLOG Data Source term, 'Data Feed' or even 'Data Source' often was used to name the supported feeds for the Tivoli Event Pump product. With the introduction of the new source of information, the differentiation between feeds and sources should be made. So the term 'Data Source' is used throughout this article to mean supported sources of data like SYSLOG and JOBLOG. The 'Event Feed' term is used to mean supported products like CICS, DB2, IMS, and other similar products.

A summary of the currently supported feeds is shown in the following figure:

SMS Event Feed

With the SMS event feed, you can use the Tivoli Event Pump to monitor the following SMS resources:

  • Disk devices
  • Storage groups
  • Storage volumes

The following two types of monitoring are supported:

  • SMS events monitoring
  • Interval monitoring of exceptions (performance and space monitoring)

SMS events monitoring is a standard trapping of SMS-related z/OS system console messages. This type of SMS monitoring is implemented based on the Event Pump Customizer facility.

Use the MONITOR TYPE=STORAGE registration statement to enable and configure this type of SMS monitoring. As a result, z/OS messages starting with IEA, IEC, IEE, IEF, IGD, and IOS are registered as SMS events through the use of the default configuration member.

Interval monitoring is implemented based on the RMF Sysplex Data Services and IDCAMS DCOLLECT data. In this case, the Tivoli Event Pump generates events based on interval collection of performance (disk device) or space (disk volume) metrics. These events are created internally by polling both Sysplex data services and DCOLLECT data and then reporting the exceptions.

To configure this type of monitoring, use the SMS registration statement. The SMS registration statement defines the registration of SMS exceptions based on the SMS exception type and SMS profile type. The following exception types are supported:

  • DPE device performance exceptions
  • CPE cache performance exceptions
  • DSE space usage exceptions

The z/OS Discovery Library Adapter (DLA) is used to discover the number of SMS resources. These SMS resources are represented by using the StorageVolume Common Data Model (CDM) class. For the full representation of these resources in the IBM Tivoli Application Dependency Discovery Manager (TADDM) and IBM Tivoli Business Service Manager (TBSM) products, new DiskDevice and StorageGroup classes, and the corresponding update of SMS discovery have been added to the TADDM topology.

Tivoli AF/Operator event feed

The Tivoli Event Pump interface with IBM Tivoli AF/OPERATOR is implemented based on the Event Pump External data interface (EDI). The EDI interface enables an external application program to pass text-based messages directly into the source collector on the same z/OS system.

This feed allows the transfer of events collected by Tivoli AF/OPERATOR to the EIF Probe.

BMC MainView event feeds

Support for the following BMC products have been added:

  • BMC MainView AutoOPERATOR
  • BMC MainView Performance Monitors:
    • BMC MainView for z/OS
    • BMC MainView for DB2
    • BMC MainView for CICS

The Event Pump interface with BMC MainView AutoOPERATOR is implemented based on the EDI.

Interaction with BMC performance monitors is implemented based on processing of the related z/OS system console messages. To enable this enhancement, configure the BMC MainView performance monitors to direct messages to the z/OS system console.

The MONITOR TYPE=MAINVIEW SUBSYS=ZOS/DB2/CISC registration statement should be used to enable and configure BMC performance monitors interaction.

The set of BMC feeds allows the transfer of events collected by BMC products to the EIF Probe.

Tivoli® Event Pump for z/OS® V4.2.2: New data source

The purpose of the JOBLOG Data Source is to monitor the specified JES SPOOL data sets and associated trapping messages from these data sets.

To configure JOBLOG data source, you should complete the following two steps:

  1. Use the SOURCE TYPE=JOBLOG registration statement to specify the SPOOL DD for the particular job you want to be monitored.
  2. Use the ZEVENT Customizer registration statements to set up messages that you want to be trapped.

You must include two mandatory parameters in the SPOOL DD statement: JOBNAME and DDNAME. All other parameters are optional. The definition for the JOBNAME and DDNAME parameters does not adequately define a particular SPOOL data set in the JES JOBLOG feature. Several jobs with the same name and SPOOL DD statement name might be included in the data set. In this case, the JOBLOG manager automatically monitors all SPOOL data sets that are associated with a specified SPOOL filter. You can filter a SPOOL data set by changing optional parameters such as STEPNAME, USERID, and other parameters.

Tivoli® Event Pump for z/OS® V4.2.2: Merge address spaces

Merge of the Source Collector and Event Distributor

The Historical Event Pump consists of the following three address spaces:

  • Source Collector
  • Data Space
  • Event Distributor

To eliminate cross address space communications and to simplify customization efforts, the Source Collector and Event Distributor have been merged into a single combined address space known as the Master address space.

In Tivoli Event Pump V4.2.2, configurations for both address spaces 2 and 3 are supported.

Tivoli® Event Pump for z/OS® V4.2.2: Support enhancements

Enhanced logging

Implementation of additional debug and trace facilities have been started in the previous release and enhanced in release V4.2.2. In V4.2.2, you can enable or disable additional messages by using startup parameters or the modify console command. You are not required to have these options enabled. But in some cases, IBM Software Support personnel might request that you enable these options to help gather additional information for problem analysis.

In V4.2.2, these options have been implemented for the JOBLOG monitoring and Event Pump Customizer.

See the following examples of JOBLOG debug and trace data:

IBM Support Assistant add-on utility for the Tivoli Event Pump

One more new function that is not directly related to V4.2.2 but that has been released recently is the IBM Support Assistant (ISA) add-on utility for the Tivoli Event Pump. The Support Assistant is a free tool that helps you answer questions about IBM products and tools. If you can't find a solution, you can open up a PMR (problem management record) with the Support Assistant Workbench. A Support Assistant add-on is an addition to the IBM Support Assistant that helps you with a particular product. The Tivoli Event Pump add-on contains helpful links and support information for the Tivoli Event Pump product.

Conclusion

The Tivoli Event Pump V4.2.2 is a significant milestone for the Tivoli Event Pump product. It covers all aspects of product development. Moreover, the JOBLOG Data Source is one of the most exciting things about the new product release. The JOBLOG Data Source extends the scope and functional superiority of the Event Pump capability to manage message processing and reflect the status of the application.
