True or False: Customers pay for every serverless function Datadog monitors, even if a function does not execute in a given month.

The assertion is false because Datadog does not charge customers for every serverless function that is monitored if that function does not execute in a given month. The pricing model is designed to only account for actual usage, meaning that customers are billed based on the execution of the functions rather than for monitoring them on an idle basis. Therefore, if a function remains dormant and does not execute, it does not incur monitoring costs for that period. This approach allows users to manage costs effectively, especially in environments where serverless architecture can lead to variable function usage. The other options imply a different billing mechanism that does not align with Datadog's billing policy for serverless functions.
