Linux Trace Toolkit Next Generation 2.13 Facilitates Quick Reaction To Kernel/User-space Instrumentation Hits

LTTng has been called "the killer app for system-level debugging and performance tuning." And now long-time Slashdot reader compudj writes: It's the official release of LTTng 2.13 — Nordicité! LTTng is a kernel and user-space tracer for Linux. The most notable features of this release are:

- Event-rule matches condition triggers and new actions, allowing internal actions or external monitoring applications to quickly react when kernel or user-space instrumentation is hit

- Notification payload capture, allowing external monitoring applications to read elements of the instrumentation payload when instrumentation is hit.

- Instrumentation API: vtracef and vtracelog (LTTng-UST)

- User space time namespace context (LTTng-UST and LTTng-modules).

Dtrace for linux

Nice we get this in linux. Claps hands!

I should add, LTT has been in development for at least 10 years.

Dtrace.

Whoo Hoo. Give Solaris a run for it's money.

At least you know it's a real open-source project that received more technical than marketing effort: worse naming scheme ever.

It's actually one of the minor factors I look at when I evaluate an open-source tool: the slicker the name, the more likely there's someone with more flair for bullshiting than coding behind it. Some of the best tools out there have really terrible names or acronyms, and I'm convinced coding abilities and naming abilities are mutually exclusive.

IBM's GTF Trace Facility was first

GTF is fantastic, but there is an overhead cost. Nice to see *ux catching up. Modern PC's are different, as graphics cards, firewire and so called management CPU's have DMA to do things behind your back.
