Can I disable local-file-writing in lttng-relayd to avoid the disk space
overhead, only using it as a live viewer?

Not explicitly, but you can store your temporary files on a tmpfs file
system (see lttng-relayd(8) --output command line parameter), which will
only keep the relayd files in memory, and use the tracefile rotation
feature to prevent the files from growing forever, e.g.:
https://lttng.org/docs/v2.13/#doc-enabling-disabling-channels
Example:Create a Linux kernel channel which rotates eight trace files of
4 MiB each for each stream.
lttng enable-channel --kernel --tracefile-count=8 \
--tracefile-size=4194304 my-channel
See lttng-enable-channel(1) for more info.
I hope this helps!
Mathieu

I am not sure why you bump this email thread. I already answered here.
Perhaps you did not receive my reply ?
