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).
