Phoronix: Oracle Is Working To Upstream More Of DTrace To The Linux Kernel & eBPF Implementation

While DTrace prospects for the Linux kernel are no longer viewed as magical or groundbreaking as they once were more than a decade ago, Oracle continues to work on its DTrace port to Linux and extending its reach beyond just their "Unbreakable Enterprise Kernel" for their RHEL-cloned Oracle Linux. Oracle now says they are working towards upstreaming more work as well as getting an eBPF-based implementation for the kernel...

"We'll see what comes of this DTrace work for Linux but we're not holding our breath."

Indeed, this is Oracle after all. Funnily enough I've spent the whole week at work looking at bpftrace which seems to be the successor to DTrace on Linux at least. Even when it comes to USDT probes it's compatible with DTrace's, so there's quite a lot of software out there that can advantage of this, aside of course from C functions and Kernel functions. Also want to point out that Brendan Gregg (and likely others, though at least him) who were the primary developers and evangelists of DTrace are now using bpftrace and other eBPF tools.
