How can I test the expense of serialization and deserialization in spark?

Hi, 
       How can I get the total expense of serialization and deserialization in spark?
       When I run an application, I only find “Task and Result Serialization Time” within Summary Metrics for ….Tasks   on Spark WebUI.

    Thank you.
