Integration of trace buffering and aggregation tools

Session information has not yet been published for this event.


One Line Summary

Discussion on use-cases facilitated by combining trace buffering (e.g. Ftrace, Perf, LTTng) and live aggregation (e.g. eBPF, SystemTAP) technologies.


Within the tracing tooling found in the Linux ecosystem, some tools focus on kernel tracing, whereas others focus on user-space. Some traditionally take a post-processing analysis approach, whereas others perform in-kernel aggregation.

As the scope of the Linux tracing infrastructure widens, it is more important than ever to discuss how tools can be combined to fulfill use-cases that would be hard to tackle with each tool alone.

    Mathieu Desnoyers main contributions are in the area of tracing (monitoring/performance analysis/debugging) and scalability, both at the kernel and user-space levels. He maintains the LTTng project, the Userspace RCU library, as well as the Linux kernel membarrier system call. He works in close collaboration with the telecommunication industry, many Linux distributions, and with customers developing hardware scaling from small embedded devices to
    large-deployment servers. He is CEO and Senior Software Architect at EfficiOS.
