A Plethora of Java Performance Monitoring Tools...! :)

We have suddenly encountered a heavy demand for light-weight, easy-to-use tools to perform some "detective work" and diagnose Performance bottlenecks and the in-famous Out-Of-Memory Errors in Java environments like Tomcat Server instances, etc.

Our popular Java IDE, Eclipse, also has a new Memory Analzer tool---you can read a nice little article on it at :- http://blog.richeton.com/2009/06/12/memory-analysis-with-eclipse-35/

But of all these tools, the one I liked the most is the newest VisualVM tool---which, unfortunately is provided  ONLY with JDK 1.6 update 7 and above as of now...

This tool has a very nice, unified Interface, with the provision of Installing other plugins to enable monitoring things like Glassfish, Tomcat, etc..

It also provides very neat features to generate Heap-dumps, try to perform Garbage Collection (GC), and plugins &/or tabs integrating the display of  jconsole, visualGC parameters, etc.

Just decided to share this Thread-Dump---of one of the millions of threads running in my mind today...! :)

Purr-haps, it will help some-one...some-where...some-how..some-when..?? :))

Well..here it is..below...my version of the He(ART)...! :)

How is it..!??!?
(Look @ the shine on it..!!! )

And if you are curious, well, the figure above was made by drawing many nested HEART-Curves...one inside the other...(like the layers of Onion--
Allium cepa..! :) )...

And each of such layer is given as below...

...this is done by a parametric-set of equations that I crazily obtained by pure, sheer Serendipity, and Stubborn-ness in terms of tweaking various parameters with a MAD Hope against OLL rhyme or reason...!! :)
[Note : (a,b,c) = (3,2,2) ]

There then, is it NOT better than the "blunt" 
Cardioid ? What do you reckon..? ;)

I think I should call it Ugare's Heart..!??! ;-)

Truly..when we are (B/M)AD-ly in LOVE...we tend to get some immensely beautiful things...!! :)

And even Science, has to forgo ALL Logic, and plunge madly, with Intuition and Hope, to uncover new (de)-Lights..!!!??

Love & Cheers !

Wherever you go, go with ALL your HEART.

The Cardiod


You must surely have heard of the
Cardioid---which produces a supposedly HEART-like shape.

But why am I telling you this well-known(?! :) ) fact/entity..?? :)

Well...that is just to put it in purr-spective---because I would like to show you the HEART-like shape that "Flew to me"--yes, flew is the word----flew magically to a hapless, clueless Me....when I was experimenting this weekend...alone...in my room... :)

Ever since I was introduced to the Cardioid, I was NEVER happy with its "bluntness"!
I needed something Sharp & more closely resembling the Heart-shape that we are accustomed to seeing on one of the suits of playing cards..!

I created the following figure...with the equation as mentioned below...
(Click on the pic below..!)

So....jussst wait fer the HEART-shape that....flew to Me...! :)
