Proactively Monitor and Manage Your z/OS System in Real Time

ASG-TMON for z/OS is a dynamic solution for monitoring every area of IBM's z/OS operating system across every partition in your enterprise.

It provides real-time performance information on important software and hardware resources and long-term online data for after the fact analysis of resource usage trends, service levels, I/O contention, job delays, exceptions, and more. It is designed specifically for systems programmers, performance analysts, application tuners, and operations personnel, and it includes powerful exception processing and productivity-enhancing utilities.

Differentiators

  • Detailed day-of-week and time-of-day sensitive exception monitoring that automatically issues operator messages and JES2 commands

  • Detailed XCF activity in Sysplex environments

  • Delay analysis for site and SRM-defined workloads, which identify factors impacting performance of jobs, started tasks, and TSO sessions

  • Identification of jobs and I/O bottlenecks causing data set contention

  • Monitors TSO response time at the period level

  • Instruction-level traces to help identify looping jobs and inefficient code

  • Validation of effectiveness of storage isolation parameter changes

Benefits

  • Monitors z/OS performance in real time across your enterprise

  • Stores short- and long-term performance data online, collected and summarized to your needs

  • Focuses access of long-term data using powerful filtering criteria so that you can easily find “after-the-fact” job delays and I/O contention

  • Exploits zIIP processing, reducing product costs

  • Provides subcapacity MSU forecasting to help monitor and avoid cap breaches causing cost overruns

  • Integrated with IBM’s Health Checker for fast problem analysis and resolution
