Solaris' Dtrace in Detail

paulkoan writes "The Register has a further details about the new Dtrace systems utility bundled with Solaris 10, along with pictures of the authors, and user testimonials. It also highlights Suns vague assurances that this (if it lives up to the hype) amazing utility may or may not end up in the public domain."

And what is DTrace?

[Anonymous Coward]

It looks like it's an allround system monitoring and administration tool. But how is it different/better than a well-sorted collection of individual tools, each doing one job as good as possible?

terrrible article

This article seems like it was written by Sun. I bet it's one of them junket articles, Sun must be a major sponsor of theregister.co.uk or something...

The article says what this D-Trace does, but yet, doesn't... Not to mention it's neither objective, review like, and even fails to mention alternatives or relative tools

Definately one of the poorest software article's I've seen in a while

Slashdot is making me bitter (-;

I must agree that the article is pretty positive about the whole thing. But a positive review is not necessarily a bought review. In fact, the article does contain an angle that is not likely to be sponsored by Sun: open sourcing it, and open sourcing solaris. They explicitly make fun of Sun's president, who is evading their questions about open sourcing DTrace. From the article:

So there you have it. DTrace may or may not end up in the public domain. Glad that's settled.

No, linux does not already do this.

Solaris users could not care less whether Sun ports it to linux or not.

Sun are *not* evil because they don't immediately give away the source to a product which has taken them years and $$$s to develop and which gives them an edge in a competetive market.

Some people just prefer Solaris. If you prefer linux, that's fine.

Wasn't meant to sound superior! I use both (and OpenBSD) myself. I'm expecting this thread to be full of ill-informed "linux does this Slowaris is teh sux" posts and whining about "why won't they GPL it it"?

So I guess I'm saying, if you're 100% linux, that's cool. I certainly don't need to hear about j00r leet gentoo boxen in a Solaris thread. You know the kind of person I mean!

Re:Microsoft perfmon

are you kidding? DTrace lets you do this not just per process, but per instruction, across CPUs. Comparing DTrace to perfmon is like comparing a Ferrari to a tricycle.
