My system is centos 7.4 with atop-2.3.0-8.el7.x86_64.
I already have 3 days log in var/log/atop, such as atop_20190312 atop_20190313 atop_20190314.
I want to find out the peak period of CPU consumption in those 3 days.
Based on this post,I tried:
atopsar -r /var/log/atop/ -A -R 3 -c |head
but failed.

I am sorry to say that as I know, atopsar is not able to combine several days.
Selection the date:
You can use -r to directly read one atop-log file. If you need to check yesterday or the day before, you can use -r y. If you add y you can select even older days: -r yy would be the day before yesterday.
Selection the right report
You can either select all reports with -A or select for example CPU only with -c.
Selecting both doesn't make sense.
Conclusion
Since you want to see the cpu utilization for 3 days, you can see them:
Today:
# atopsar -R 3 -c |head
Yesterday:
# atopsar -r y -R 3 -c |head
2 Days ago:
# atopsar -r y -R 3 -c |head
Hope that helps.

Hi @kittygirl . You started with-R 3in your question. It means: Summarize 3 samples into one sample. Please consult the man pages or linux.die.net/man/1/atopsar for more details.
