What we have
- kstats - Solaris kernel statistics
- consumers (in C) - iostat, vmstat
- perl interface - module and kstat(1M) command
- no other language bindings (?)
- JKstat provides access from Java applications
- Provides:
- JNI library
- jar file with classes
- some sample tools
Software is developed using the OpenSolaris version of the Studio 10 compiler, on Solaris 10 and OpenSolaris, using Java 5. It should, however, work fine on previous versions of Solaris and Java - I'm not using any of the more recently added features.
There is a Java kstat interface in the Resource Pools project, but it's not a general purpose interface. There is enough in common, though, that it might be feasibel to merge that with this.
kstatbrowser - gui browser

The statistics naturally form a tree structure, so browsing through a JTree is natural.
There are accessories for specific kstats.
Accessories - Gui widgets
- In browser, for specific kstats
- IO kstats- read and write rates
- network interfaces - bytes in/out
- bge - packet size histogram
- Standalone applications
- jcpustate
- jiostat
Future Work
- Firm up the API
- More accessory widgets
- Enhance standalone tools
- Improve performance
