Subje= ct: [lttng-dev] Question about rotating session limitations

Hello,

On https://lttng.org/man/1/lttng-rotate/v2.12/ one of the limitations is l= isted as:

The lttn= g rotate command only works when:

=C2=B7No channel was created with a configured trace file = count or size limit (see the --tracefile-size and --tracefile-count options i= n lttng-enable-channel(1)).

However on v2.12.1 I am able to= :

  1. Create a userspace s= ession
  2. = Create a channel w/ configured trace file count and si= ze limit
  3. Start tracing
  4. lttng rotate
    5. =

Within each chunk these restric= tions are respected.

Therefore my question is what d= oes this limitation actually mean? Is it more so in the direction that the = archives will not respect these limits because the chunks accumulate? Or am= I missing the point entirely?


Hi Zach,

I think it's simply a documenta= tion error, probably on my part from misadvising Philippe.
I'll open a change against the manual page.

Thanks for repor= ting this!
J=C3=A9r=C3=A9mie

Thanks,

Zach
