JProc

31 May 2026: version 1.0. Download | JProc on GitHub

JProc is a simple java jni interface to the Solaris and illumos /proc filesystem.

The aim is to allow java applications running on Solaris/illumos to obtain the sort of process data that you can get from tools like ps, ptree, prstat, and top.

Above is a simple screenshot, a simple gui tabular process view. To use, download, unpack, cd into the jproc-X.Y directory, and run ./jproc info.

Above is a screenshot of the aggregate user view. You can drill down into a user's process list from the right-click menu. This is available via ./jproc userinfo.
