[ltt-dev] Question about timestamp using textDump module

[Ya-Yunn Su]

Hi,
   I'm using lttng on a Xen environment.  I applied the lttng patch to 
the driver domain kernel and instrumented the driver domain.  I have a 
question about the timestamp in the textDump output.  From my 
understanding, the timestamp is in sec.nanosec format, so the difference 
between two entries is also in sec.nanosec format.  However, if I take 
the earlies and latest timestamp within a trace as the duration 
(hundreds of thousands second), it is much longer than the actual time I 
enable the tracing on (at most a minute).   Am I interpreting the 
timestamp wrong?  Any input is appreciated and thanks in advance.

Thanks,
Ya-Yunn
