'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).' -- source: https://linux.slashdot.org/story/21/08/07/182213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
