Debugging Microconference at Linux Plumbers Conference?

Debugging Microconference at Linux Plumbers Conference?

[Omar Sandoval]

We are gauging interest in hosting another Debugging Microconference at
Linux Plumbers Conference this year. Topics would focus on common
challenges people are facing with debugging tooling: collecting and
analyzing core dumps, doing live analysis, developing more powerful
debugger features and tools, etc.

We last had one in 2023 which went well. The Linux System Monitoring and
Observability MC last year also had some overlap.

If you would be interested in presenting or attending, please let me
know (either on- or off-list is fine) so we can get a sense of whether
we should do another one.

Thanks!
Omar

I'd be interested in attending and potentially starting a discussion
over a few things that we've been working on at CoreWeave!

Specifically:

(1) Capturing crash dumps with tight memory and space constraints at
    scale

(2) Triaging, deduplicating, and categorizing crash dumps in
    production

(3) We've been experimenting with out-of-band kernel introspection
    (using drgn in a DPU to introspect the host with one-sided RDMA
    ops). Would be cool to see if others have worked on the same or
    similar problems.

Thanks,
Serapheim

Just to update the list, instead of having a separate Debugging
Microconference, we're going to submit topics to the Monitoring and
Observability MC since that has a lot of overlap:
https://lpc.events/event/20/sessions/262/.

Serapheim: Usama, who is one of the Monitoring and Observability MC
leads, expressed interest in your topics and asked if you could submit
something.

Thanks,
Omar
