Hello Vikas Agnihotri,
Sounds like you want something with nice colorful, dynamically scaling
graphs
that will clearly point out the numbers and what they mean, so that non
technical management types can clearly understand very quickly what exactly
is happening on Solaris, and Oracle as well for that matter, and when/why.
A great tool for exactly what you're looking for, DPMonitor, can be found at
www.deltekonline.com. They have a free trial evaluation license with the
product when you download it. It will profile Solaris, AIX, Windows and
Oracle,
but the free trial evaluation version will only profile one Agent OS. All
these OS
platforms measureable with one tool, "apples to apples" as they say.
It has an extremely low overhead Agent component that runs on Solaris.
Agent data is then sent back to a Windows PC that acts as "performance
monitor console component" that crunches numbers and displays graphical
results
It's available for short term lease as well - so you can profile before and
after
upgrade or replacement - analysis, and be able to show management exactly
what is going on when, and how much resources are being consumed. It's also
great for showing areas where performance improvements can be made which
may help save costs of an upgrade altogether. Either way, everything is 100%
justifiable and clear for even the most non-technical to understand..
There are many other products out there - some free, some not.
HTH.
