Hi All,
We're looking at the SystemTap tools that bundled with the Eclipse Linux Tools,
to be specific the latest Indigo. When I tried to open the SystemTap IDE
perspective, I got the following exception (pasted below). My questions is:
Is SystemTap an actively maintained project, since the info I found on the
internet are quite old. If so, can someone provide me a pointer to some doc
about its features, usage, etc?
Greatly appreciate your help.
- Jessica
