Hi,

We use LTTng 2.0 with a limited file system on the target to receive the trace 
logs:

  Extract of fstab file:
  tmpfs        /dev/shm    tmpfs  size=64M,mode=777,noauto            0   0

When tmpfs is full, trace logs are corrupted. Since it is very difficult to 
control the tracing to avoid this, we would need a real flight-recorder mode 
where the files on the disk have a pre-defined (maximum) size and where either 
discard or overwrite mode can be applied.

Is there such a thing or some other solution to the problem?


Cheers,

Fredrik Östman
