Compliance with monitoring and measurement requirement

I assume you are referring to ISO 27001 clause 9.1 or ISO 22301 clause 9.1. 

Measuring means that you set certain objectives (e.g. maximum number of incidents) and that you evaluate if your achieved numbers are within your expectations. 

Monitoring means that you track the performance of a particular process or a system (e.g. log activity) and you react if the trends are out of the ordinary.
