What do you suggest to get some reliable figures?

sar is often recommended, see

Can you exclude other reasons like vacuum / vacuum freeze?

In the current case it was a problem in the hypervisor.

But I want to be prepared for the next time.

The tool sar looks good. This way I can generate a chart where I can see peaks. 

.... But one thing is still unclear. Imagine I see a peak in the chart. The peak
was some hours ago. AFAIK sar has only the aggregated numbers.

But I need to know details if I want to answer the question "Why?". The peak
has gone and ps/top/iotop don't help me anymore.

Any idea?
