So we're not getting DTrace proper, it seems. Instead something else will stem up from the various linux tracing systems. Maybe this BPF-based one.
It's a shame. One of the nice things about dtrace was that there was a book on it. Good, in-depth documentation on performance tools is hard to find.
- brendangregg 10y agoThanks, I wrote the DTrace book with Jim Mauro, and there will be a BPF tracing book as well. BTW, I wouldn't say "maybe" regarding BPF, as it's integrated in the Linux kernel (unlike most of the other tracers, which are add-ons). Sooner or later everyone who runs Linux is getting it.
- BrianJ123 10y agoI've been waiting for this for since Solaris. Thanks!
- cthalupa 10y agoI think I bother you about a new tracing book for Linux every time one of your articles is posted, so I'll give my obligatory: We want a new Brendan Gregg tracing book! ;) Things have been moving so fast it's probably a good thing you didn't. It sounds like 4.9 will slow a lot of that down to a more manageable pace for writing a book, though.
