Here are the steps and explanations for ensuring that requests for wwwjelecloud.com from any of your Azure virtual networks resolve to frontdoor1.azurefd.net:
To use a custom domain with your Azure Front Door, you need to create a CNAME record with your domain provider that points to the Front Door default frontend host. A CNAME record is a type of DNS record that maps a source domain name to a destination domain name1.
To create a CNAME record, you need to sign in to your domain registrar's website and go to the page for managing DNS settings1.
Create a CNAME record with the following information1:
Source domain name: wwwjelecloud.com
Destination domain name: frontdoor1.azurefd.net
Save your changes and wait for the DNS propagation to take effect1.
To verify the custom domain, you need to go to the Azure portal and select your Front Door profile. Then select Domains under Settings and select Add2.
On the Add a domain page, select Non-Azure validated domain as the Domain type and enter wwwjelecloud.com as the Domain name. Then select Add2.
On the Domains page, select wwwjelecloud.com and select Verify. This will check if the CNAME record is correctly configured2.
Once the domain is verified, you can associate it with your Front Door endpoint. On the Domains page, select wwwjelecloud.com and select Associate endpoint. Then select your Front Door endpoint from the drop-down list and select Associate2.

Here are the steps and explanations for configuring VNET1 to log all events and metrics and query them by using KQL:
* To enable logging for VNET1, you need to create a diagnostic setting that collects the platform metrics
* and logs from the virtual network and routes them to one or more destinations. You can choose to send the data to a Log Analytics workspace, a storage account, an event hub, or a partner solution1.
* To create a diagnostic setting, you need to go to the Azure portal and select your virtual network. Then select Diagnostic settings under Monitoring and select + Add diagnostic setting1.
* On the Add diagnostic setting page, enter or select the following information:
* Diagnostic setting name: Type a unique name for your diagnostic setting.
* Destination details: Select the destination where you want to send the data. For example, you can select Send to Log Analytics workspace and choose your workspace from the list.
* Log: Select the categories of logs that you want to collect. For VNET1, you can select NetworkSecurityGroupEvent and NetworkSecurityGroupRuleCounter as the log categories2.
* Metric: Select AllMetrics to collect all the platform metrics for VNET12.
* Select Save to create your diagnostic setting1.
* To query the events and metrics from the Azure portal by using KQL, you need to go to the Log Analytics workspace that you selected as the destination. Then select Logs under General and enter your KQL query in the query editor3.
* For example, you can use the following KQL query to get the top 10 network security group events for VNET1 in the last 24 hours:
NetworkSecurityGroupEvent
| where TimeGenerated > ago(24h)
| where ResourceId contains "VNET1"
| summarize count() by EventID
| top 10 by count_
Copy
* Select Run to execute your query and view the results in a table or a chart3.
