Azure Monitoring

As soon as you create an Azure resource, Azure Monitor is enabled and starts collecting metrics and activity logs. Additional configuration allows more data to be gathered.
Azure Monitor Metrics stores numeric data from monitored resources into a time series database. The metric database is automatically created for each Azure subscription.
- Use metrics explorer to analyze data from Azure Monitor Logs.
  - Available from resource’s tab
- Azure Monitor Logs collects logs and performance data where they can be retrieved and analyzed in a different ways using log queries.
  - Use a Log Analytics workspace to collect log data and query it
Resources generate these monitoring data types:
- Activity log: subscription level events for operations on each resource (e.g. starting, modifying a resource configuration)
- Platform metrics - number values of resources collected at time intervals
- Resource logs - operations done by a resource, e.g. making a request, requires a diagnostic setting to send them to logs
- Virtual machine guest metrics and logs - for guest OSs of VMs, requires an agent on the VM
Activity logs, platform metrics types can be seen in a resource’s tab. Insights are available in the monitoring menu if available for the resource
Logs can be sent to an log analytics workspace or other storage using the resource’s diagnostic setting
