Create a CloudWatch dashboard

Your operations lead at NovaTech wants a single pane of glass to monitor the TenantReportReader Lambda function. Right now, the team checks metrics manually each morning, which is slow and error-prone. A custom CloudWatch dashboard with a line widget will give everyone instant visibility into invocation trends.

In this exercise you will create a new CloudWatch dashboard, add a line widget for the Lambda invocation metric, and save the dashboard.
