JPicus - the tool for Java I/O analysis
“If I want to read something nice, I sit and write it myself!”
Mark Twain
I heard this quote just a few weeks ago. Do not know whether it is really Mark Twain that said it, but it is an interesting quote.
This is one of the “jokes” a friend of mine used in his presentation at JavaOne 2009. More specifically Technical Session TS-4588 which is all about analysing your I/O.
Have you ever wondered
- How much I/O does my program use?
- How much time is spent in I/O?
- Hot spots. What can be improved?
- Which handles are currently open?
- Where was a handle opened and closed?
- Why did a delete operation fail?
- Where and when was this file deleted?
- Was there some interference from external processes?
Well Pavel (my friend I have mentioned) has definitely wondered. A few months ago he came to me with a question whether I could assist him in implementing such a tool. A tool that will give us all these answers.
Generally my part was to implement the integration with Eclipse. A few views, a wizard, some actions, a nice perspective. And - this is the result
If you think such a tool could assist you visit JPicus home page.
It is still only free. But we are working on making it open 
And there is more on JPicus coming in the near future.
