the Usenet tradition is _rarely_ to encourage, only to discourage.

Please post what you have found about the products you evaluated.

One of the question my employers RFQ on EMS asked was 'describe what
means the product has for measuring end to end response times'. 

The responses were suprisingly poor in that

1 Most proposed synthetic transactions - completely unsuitable for
updates or write once

2 only one even mentioned the use of (the EMS purchasing organisations
own) RMON2 probes and _none_ mentioned other comparable equipment such
as the Packeteer

3 only one mentioned other means of doing so (server side APM
instrumented applications) in the general case.

It seems to me that you are looking at best of breed solutions for what
you are prposing, but I think analysing the delays in multi-tier (so
long in web, much longer in the DB, really long in the app server ..)
sounds hard.

Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
