VIT CIA (ODPK,PKI/PKO/MPDU) trace converter

VTAM Internal Trace Option CIA traces the DLC Layer of a z/OS LPAR. As such the first couple of bytes of all inbound and outbound IP packets are traced in PKI/PKO, ODPK or MPDU trace entries. The trace formatter shipping with VTAM (ISTRAFT1 or IPCS) are not very helpful to analyze the IP packets contained in those entries.
Suggestion: Povide a VIT2CAP trace converter that converts all IP packets flowing through the DLC layer into sniffer or tcpdump format to be used by external tools like wireshark. This would speed up problem source identification especially for intermittent problems if the VIT trace with CIA option is already running into HVCOMMON storage and a socket application takes a dump (or sets a slip to trigger for an event).

    We believe that this requirement can be addressed by using the CSDUMP command (and being sure to include the TCPNAME parameter) to capture the dump on the event (e.g. VTAM message) you are monitoring and also capture the packet trace itself. (This was made possible because in V1R13 we moved the packet trace to 64bit common and all of common is included in CSDUMP). Hopefully this solution will satisfy your request and it will be much more efficient in terms of CPU cost and the volume of date collected.
