SmartTrace

Packet tracing is a valuable tool for troubleshooting network connectivity problems. SmartTrace is a real-time packet tracing facility.

SmartTrace enables you to do the following:

Initiate a trace on demand (often while a problem is occurring and while you can still catch it), and view the results while the trace is running. You can have separate traces for different resources running at the same time.
Define trace criteria using a panel interface. You can define a number of traces to wait on infrequent and difficult to capture network activity, and to pinpoint complex failure scenarios. You can also set criteria that cause a trace to stop when matched. Samples are provided to make it easier to define a trace that is relevant to your problem.
Export trace data to libpcap or CTRACE format, enabling you to use the trace data with other packet trace viewers.
Import trace data in libpcap format, enabling you to use CA NetMaster NM for TCP/IP to decode packets captured by other means.

CA NetMaster NM for TCP/IP also supports IBM's Component Trace (CTRACE) facility.
