LTTng 2.13 Released, Enables External Monitoring Applications to Quickly React to Kernel and User-space Instrumentation

Today is the official release of LTTng 2.13 – Nordicité! It is the result of one year of development from most of the EfficiOS team.

The most notable features of this new 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).
