This article describes the monitoring data generated by Azure virtual network. Azure virtual network uses [Azure Monitor](../azure-monitor/overview.md). If you're unfamiliar with the features of Azure Monitor common to all Azure services that use it, read [Monitoring Azure resources with Azure Monitor](../azure-monitor/essentials/monitor-azure-resource.md).

## Collection and routing
26-
27-
Platform metrics and the Activity log are collected and stored automatically, but can be routed to other locations by using a diagnostic setting.
28-
29-
Resource Logs aren't collected and stored until you create a diagnostic setting and route them to one or more locations.
30-
31-
See [Create diagnostic setting to collect platform logs and metrics in Azure](../azure-monitor/essentials/diagnostic-settings.md) for the detailed process for creating a diagnostic setting using the Azure portal, CLI, or PowerShell. When you create a diagnostic setting, you specify which categories of logs to collect. The categories for *Azure virtual network* are listed in [Azure virtual network monitoring data reference](monitor-virtual-network-reference.md#resource-logs).

For a list of available metrics for Virtual Network, see [Azure Virtual Network monitoring data reference](monitor-virtual-network-reference.md#metrics).

Azure Monitor alerts proactively notify you when important conditions are found in your monitoring data. They allow you to identify and address issues in your system before your customers notice them. You can set alerts on [metrics](../azure-monitor/alerts/alerts-metric-overview.md), [logs](../azure-monitor/alerts/alerts-unified-log.md), and the [activity log](../azure-monitor/alerts/activity-log-alerts.md). Different types of alerts have benefits and drawbacks.
