JKstat 0.17 - includes charts

I've been gradually continuing work on JKstat. The latest version (0.17) has a number of code cleanups, but also includes charting capability. (Uses JFreeChart.)

You can right-click on any numerical statistic in kstatbrowser and chart that statistic. Here's an example:

JKstat 0.15

I've made a new version of JKstat available.

There are quite a few changes underneath. I'm very grateful to Tom Erickson for sending me a bunch of enhancements and fixes. Some of them made it into this version fairly directly - particularly the sorting of kstats in the browser.

This version has also been revamped and now requires Java 5. I had been thinking about modernizing the code for a while, but had always put it off. Tom again provided the impetus, as he went ahead and used generics in the fixed version he sent back to me. I reimplemented it myself, so I could actually understand what I was doing to my code.

I actually went and rewrote solview first. This was a useful exercise in itself, as one of the advantages of using generics is that it makes you think harder about the way you define classes and how your code is structured. In solview I was in the middle of cleaning the code up to define Solaris packages and install clusters as proper objects, and using generics made sure I actually got that right.

JKstat was also accepted as an OpenSolaris project, so I'm going to be moving development over there soon.

Updated jkstat

It's been a while (almost a year) since I last updated jkstat, but I've just put version 0.13 up for download.

For those that don't know, jkstat is a Java jni interface to Solaris kstats, allowing you to access a wide range of useful data held by the Solaris kernel from a Java application.

One thing I have done is this version is try to improve the look of the sample applications, most of which has been achieved by replacing the rather clumsy GridLayout with SpringLayout.
