v2.0.3-beta

[tanelpoder]

This is still a beta / tech-nerd preview release. Please don't run it in busy production environments yet.

The main noteworthy change is that now there's a -o option to switch xcapture-bpf to always-on CSV output mode.

./xcapture-bpf -o /some/dirname

This will make xcapture log the 1HZ samples into hourly threads_* files in the output directory and if the stack capture is enabled (its enabled by default in -o mode), it will write any newly seen stack traces into a stacks_* file.

Unlike the hourly thread samples, a single stack file is created at xcapture startup (with a startup timestamp in it) and it just appends newly seen, not yet written stacks into the end of the single file.

This is likely the final release of the BCC-based beta / developer preview. I've hit too many limitations sooner than I had thought and will now focus on writing a proper final version of this tool (that I can be proud of!) using libbpf and a better frontend. Use the current v2 release for testing and exploring what's possible!
