# Traffic Traffic as a service metric gives you basic insights into the operational health of your model's service in production. ![Example of a Fiddler Chart displaying a model's traffic.](/files/lYjb7TWihyzLVINliqmx) ## What is Being Tracked? * ***Traffic*** — The volume of traffic received by the model over time. ## Why is it Being Tracked? * Traffic is a basic high-level metric that informs us of the model's output activity. ## What Steps Should I Take When I See an Outlier? * A dip or spike in traffic needs to be investigated. For example, a dip could be due to a production model server going down; a spike could be an adversarial attack. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
