Up on
Newsforge today: Sun to announce open source DTrace on Tuesday,
referencing the
Computer Reseller News leak, that this coming Tuesday, Sun
Microsystems is releasing the source code for its DTrace
utility.
This is outstanding news. Sun's DTrace allows admins to diagnose
running systems in real time, scripting the utility's 30,000 data
monitoring points to show information on disk I/O activity, file
opens, disk accesses, disk head seek distance by process, process
activity snooping (by UID, for example), live reporting on shell
input and output, printing keystroke activity in inbound ssh
sessions, snooping inbound TCP connections, setuid calls and lots
of other cool stuff. This is detailed drilling down that used to
take hours pouring over output without any certainty you'd be able
to pinpoint what's causing problems.
The BigAdmin DTrace page is
here. The usenet
announcement was
Introducing DTrace by Bryan Cantrill, a year ago
November.
You know awk, you can whip up DTrace scripts.
OpenSolaris.org will be a community news, discussion and support
site.
It looks as if Sun will be open sourcing
Trusted
Containers and the
Zettabyte
(self-repairing for data integrity and pooled partitions
re-sizeable on the fly) File System later this year.
