In a previous post I spoke about the use of the Web Services Navigator for development and, to some extent, the management of Web services. The second piece for this, the Data Collector for IBM Web Services Navigator is now available on IBM alphaWorks. See the link for the full description, but here's a bit of it:
The Data Collector for IBM Web Services Navigator intercepts and instruments Web service requests and responses and writes information about the Web services to a log file. This log file is used by an Eclipse-based viewer called the IBM Web Services Navigator. The Navigator processes log files that are generated by the Data Collector and generates visual representations of various characteristics of the monitored Web services.
