systemd-analyze is the command to investigate time taken by each service during boot in CentOS 7. Is there a similar utility in CentOS 6 for doing this?
update: extending the question after Lucas' comment.
If there isn't such a direct way, any thoughts on using this method to compute total time taken by boot process:
t1 = time stamp shown by
t2 = last modified time of
boot time = t2 - t1
Anything wrong with this approach?
