# ADVOPS02-BP01 Implement monitoring across each layer of your advertising stack including infrastructure, applications, and user experience
<a name="advops02-bp01"></a>

 Ensuring operational excellence in advertising workloads requires a holistic approach to monitoring. This best practice emphasizes the importance of implementing comprehensive monitoring solutions that span all layers of the advertising stack. The advertising stack includes the ad-serving infrastructure, data pipelines, application performance, and user experience. By monitoring these various components, you can gain a complete understanding of the overall health and performance of your advertising workload. This understanding helps you identify and address issues, optimize resource utilization, and deliver a seamless customer experience. With a multi-layered monitoring approach, you can proactively detect and resolve problems before they impact your business.
