Presented by Daniel Bristot de Oliveira, the webinar focuses on measuring latency, tracing factors that contribute to it, and breaking a complex scheduling problem into smaller components.
What the webinar covers
The session addresses the challenge of diagnosing real-time scheduling latency. The Linux Foundation’s event description says that black-box preempt-rt testing can reveal that latency occurs without identifying its root cause or showing patterns across cases. It presents rtla as a kernel tool that integrates measurements with kernel tracing.

For rtla timerlat specifically, the event listing describes a workflow that combines latency measurement, tracing of contributing factors, standardized automated analysis, and decomposition of the problem into smaller latency components. The webinar covers the timerlat tracer, its automatic-analysis output, and a strategy for debugging complex scheduling-latency problems. This is the Linux Foundation’s stated scope, not a guarantee of a particular result on every system. Linux Foundation webinar listing.

The event page frames the distinction as one of visibility: black-box testing can expose a latency problem, while tracing-integrated measurement is intended to help examine the factors behind it and relate different cases. It also describes rtla timerlat’s analysis as splitting a larger latency problem into smaller, more independent pieces.

This is the webinar listing’s explanation of the approaches, not a published head-to-head benchmark. The page does not provide measured results or establish that rtla timerlat will identify every root cause.
Who presented the session
Daniel Bristot de Oliveira presented the webinar. The Linux Foundation listed him at the time as a Senior Principal Software Engineer at Red Hat, with a Ph.D. in embedded real-time systems and automation engineering and a post-doctoral researcher role at Retis Lab, Scuola Superiore Sant’Anna. These are credentials given in the event listing, rather than a statement about his current employment.

The event listing and slide-deck description outline the session’s purpose and resources; they do not provide a reproducible command sequence, installation instructions, minimum kernel version, or system configuration. They also do not report quantitative performance results. For setup and version-specific operational details, use the linked tutorial and current upstream Linux documentation rather than inferring requirements from the webinar description.
