An activity log alert monitors a resource by checking the activity logs for a new activity log event that matches the defined conditions. The Toy Car Lab. You can monitor at scale by applying the same metric alert rule to multiple resources of the same type for resources that exist in the same Azure region. When you use splitting by dimensions, you can create resource-centric alerts at scale for a subscription or resource group. Because logs are semi-structured data, they're inherently more latent than metric data on information like a VM heartbeat. Criteria and Constraints Once we have identified the problem, we will identify the criteria and constraints of the project.
