For Complete Performance Management of IBM's Virtual Telecommunications Access Method (VTAM)

ASG-TMON for VTAM is a comprehensive solution for monitoring every area of VTAM activity. It monitors both internal and external influences on the performance of your communications environment.

ASG-TMON for VTAM provides in-depth analysis of all VTAM applications, including dataflow and response time information, and displays operating system components that can affect VTAM performance. In addition, ASG-TMON for VTAM gives you easy-to-use diagnostic capabilities for problems with VTAM definitions, configurations, applications, sessions, routes, and I/O devices.


  • Provides a single view of VTAM subsystems across the enterprise, and identifies and resolves performance issues before outages occur.

  • Provides system-level support including end-user response time, virtual route analysis, device analysis, and VTAM profiling.

  • Monitors application activity and configuration, including activation time, active or pending sessions, message distribution and I/O rates.

  • Establishes the thresholds that trigger electronic, audible, and visual advance warnings, enabling automated actions.

  • A real-time alternative to VTAM buffer trace supporting multiple, concurrent traces, data filtering, and interpretation.
