After almost a year in the making, Babeltrace v1.2 is out and packs a host of great features!
The first of which is the CTF-Writer API which provides an easy way for applications to produce CTF traces. This API is not meant as a tracing solution. It provides an easy way to write spec-compliant trace converters, merge existing traces and, perhaps, add CTF logging capabilities in low event throughput applications where integrating LTTng would prove impractical.
We have also overhauled and integrated the Python bindings branch into this release. These bindings now provide an easy way for Python application developers to read and produce CTF traces. Have a look at the example scripts to learn how you can roll out your own trace analysis and conversion tools!
Finally, we added an LTTng live (
lttng-live) plugin which leverages
LTTng 2.4's brand new live tracing feature. See the LTTng 2.4 release
notes for more details on this feature.
