Let $M$ be a compact Riemannian symmetric space. By the classification of Cartan, it belongs to the table of homogeneous spaces given in the Wikipedia page:

https://en.wikipedia.org/wiki/Symmetric_space

In the Berger classifiction of holonomy groups

https://en.wikipedia.org/wiki/Holonomy#The_Berger_classification

the symmetric case is omitted because

the holonomy group can easily be read off the Cartan classification in the symmetric space case.

How does this "reading off" work exactly. Can someone point to me a list of the holonomy groups of the compact symmetric spaces?
