| |
LTTng, the Linux Trace Toolkit Next Generation, is a project that aims at producing a highly efficient full system tracing solution. It is composed of several components to allow tracing of the kernel, of userspace, trace viewing and analysis and trace streaming. LTTng is open source software. It is being actively developed with the community.
Changelog: - Implement a user-space trace clock into a new clock_gettime() clock id. (will be used by the next UST release). It will provide consistent timestamps between userspace and kernel traces taken on a LTTng-enabled Linux kernel. - Moved to stable kernel 2.6.36.2 (last LTTng release targeting 2.6.36.x, moving on to 2.6.37 shortly)
Project Status: - I am currently working on a LTTng redesign to better suit the need of Linux distributions. The kernel-side work is very well advanced, and I'm now moving on to the following steps: redesign lttd/lttctl/ltt-armall with a more integrated approach (lttngtrace), and move LTTV to the new CTF (Common Trace Format). I am keeping this redesign separate from the "stable" LTTng versions for now, as it removes some of the LTTng-specific instrumentation to bring the size of the patchset down to something more appealing to distributions. The ongoing redesign is available in the lttng-modules git tree HEAD, but depends on a reduced kernel tree LTTng patchset that I have not yet released.
