A key consideration when managing a strategic legacy
application is to realize and quantify and its performance degradation
over-time. This degradation is the natural consequence of added features and
evolutions which were not always analysed in terms of performance impacts.
Although it is possible to size resources to fit most needs, you will still find
that some features will consume
all of the available resources, and no change of infrastructure bring any significant enhancement.
More, if this performance collapse is due the interactions of several software
components, no usual development tools such as profilers will help to understand
the root of the problem.
Primhill Computer's Survol and
DockIT solutions allow IT staff to qualitatively monitor resources, by
exposing hidden dependencies which impact available resources.
