XPI Inspector - new tracing tool provided by SAP
SAP have provided a new diagnostics tool, the XPI Inspector, for tracing XI issues. See note #1514898 Diagtool for troubleshooting XI.
This is particularly useful for SSL related scenarios but can be used to trace all XI adapters.
The tool is still a work in progress and further improvements are planned for the future. Any feedback you have or any suggestions for improvements will be greatly appreciated.
