dcpiepoch - Start a new profiling epoch.




Dcpiepoch starts a new profiling epoch after flushing all unsaved in-memory samples to their associated profiles in the on-disk profile database. The dcpiflush(1) command can be used to flush unsaved samples without starting a new epoch. The dcpilabel(1) command or the -bypid option to dcpid(1) can be used instead of dcpiepoch to separate out profiles for specific processes.

Epochs are designed to capture relatively coarse time intervals measured in minutes. An epoch is represented by a GMT (Greenwich Mean Time) timestamp for the start of the epoch, in YYYYMMDDHHMM format. For example, the epoch 200212042334 corresponds to December 4, 2002 at 23:34 GMT (or December 4, 2002 at 15:34 PST).

Dcpiepoch is implemented as a shell script that invokes dcpictl(1) with the epoch command.
