Is there a way for someone to take a look at system activity, like load averages and system processes that happened at an earlier time of the day? I mean is there a command for that? Say for example, I wanted to assess load averages on a machine at 9AM in the morning on the same day. How would I go about doing that? Thank you in advance UNIX/Linux community.
Yes. You need to have set it up beforehand, but if you use the
sar command with the
sysstat package/facility, you can look back at the past month's daily data.
