Manually generate sar report image to troubleshoot and how to identify the process from sar

Hello,
I like the sar report which shows CPU, Memory, IO in cumulative format. I understand I can modify /etc/cron.d/sysstat to change interval from 10 mins to x mins.

Question 1.
I want to generate the report manually like 1 or 2 minutes when I have performance issue to find what's causing the issue. How can I generate the sar binary image manually and also the sardd text report after that as well?

Question 2.
Say, the issue is CPU jumps from 5% to 80% in sar report. How do I identify what process caused the CPU jump? Does anywhere else show which process it is?
