Oracle open-sources DTrace under the GPL
Found on RThe Register on Monday, 19 February 2018
Big Red recently listed DTrace as one of the open source projects it hosts and has also created a new mailing list for discussion of what it's called a "Linux port of the Solaris Dynamic Tracing Framework."
As DTrace afficianado Brendan Gregg told us in 2016, Linux has only recently added tracing tools to compare with Sun's progeny. The prospect of bringing all of DTrace to Linux is therefore rather tantalising.
The only reason can be that greedy Oracle has done its best to try and squeeze every single penny it could out of it before it considered the project useless.
