dcpiepoch(1)
NAME
dcpiepoch - Start a new profiling epoch.
SYNOPSIS
dcpiepoch
DESCRIPTION
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.
