Description

This bug is not confirmed, but investigating the consumer's code (see consumer-timer.c), it appears that the live and switch timer concepts were merged at the introduction of the live feature.

However, now the switch timer only seems to apply to the metadata channel. This means that there is no way for the user to force a periodical subbuffer switch in order to ensure periodical data flushes.

For data channels, the switch timer is handled by the consumer, but it is implemented in lttng-ust. It is working per-spec with the right value.
