To collect metrics with the Datadog Agent, follow the instructions to deploy Agents: - If your organization is on Datadog's US3 site and you've configured the Datadog resource in Azure, use the instructions on the [Azure Native Integration](https://docs.datadoghq.com/integrations/guide/azure-native-integration.md#agent-extensions) guide. - **All sites** can use the instructions on the [Getting Started with Azure](https://docs.datadoghq.com/getting_started/integrations/azure.md#setup) guide. ### Log collection{% #log-collection %} To collect logs from specific Windows events, add channels to the `conf.d/win32_event_log.d/conf.yaml` file manually, or using the Datadog Agent Manager. For example: ```yaml logs: - type: windows_event channel_path: '' source: '' service: myservice sourcecategory: windowsevent - type: windows_event channel_path: '' source: '' service: myservice sourcecategory: windowsevent ``` For additional details, see the information for the [Win 32 event log](https://docs.datadoghq.com/integrations/win32_event_log.md#log-collection) integration. ## Data
