I take it you are running LTM as a point product and don't have
DECMcc.  You're right LTM has very limited usefulness for reporting
statistics.  DEC sells an assets package called LTMReports which
basically collects the ltm packets which are saved in a data file over
a given period of time.  you can then run LTMReports against the
collected data file to generate your reports.  for graphical reports
you need GKS and DATATRIEVE is also helpful.  being an assets package
it's not fully supported and really isn't fully developed....DEC has
spent most of their time developing DECMcc.  Oh yeah, I don't think
you can run LTMReports on the same node you run LTM.....

You might try posting to the vmsnet.decmcc news group.  some of the DECMcc
developers read that group and may be able to help you out with the 
packet formats.
