@PanamaKatharineMarquand-7579 Thanks for your question. AFAIK, Azure Monitor doesn't provide any built in dashboards. To monitor your application logs , I would suggest to use application insights and to monitor your platform logs ,I would suggest you to enable to diagnostic logs . Once the logs are collected, you can take advantage of the kusto queries and build the dashboard as per your requirement.
For more information about the diagnostic logs , you can refer this document.To learn about how to write kusto queries, refer this documentation.
