# Tutorial: View and configure Azure DDoS protection telemetry
1212

13-
Azure DDoS Protection provides detailed attack insights and visualization with DDoS Attack Analytics. Customers protecting their virtual networks against DDoS attacks have detailed visibility into attack traffic and actions taken to mitigate the attack via attack mitigation reports & mitigation flow logs. Rich telemetry is exposed via Azure Monitor including detailed metrics during the duration of a DDoS attack. Alerting can be configured for any of the Azure Monitor metrics exposed by DDoS Protection. Logging can be further integrated with [Microsoft Sentinel](../sentinel/data-connectors/azure-ddos-protection.md), Splunk (Azure Event Hubs), OMS Log Analytics, and Azure Storage for advanced analysis via the Azure Monitor Diagnostics interface.

Azure DDoS Protection applies three auto-tuned mitigation policies (TCP SYN, TCP & UDP) for each public IP address of the protected resource, in the virtual network that has DDoS protection enabled. You can view the policy thresholds by selecting the **Inbound TCP packets to trigger DDoS mitigation** and **Inbound UDP packets to trigger DDoS mitigation** metrics with **aggregation** type as 'Max', as shown in the following picture:

You can see the policy limits within your public IP address metrics by choosing the *Inbound SYN packets to trigger DDoS mitigation*, *Inbound TCP packets to trigger DDoS mitigation*, and *Inbound UDP packets to trigger DDoS mitigation* metrics. Make sure to set the aggregation type to *Max*.

It's important to keep an eye on the metrics for TCP SYN, UDP, and TCP detection triggers. These metrics help you know when DDoS protection starts. Make sure these triggers reflect the normal traffic levels when there's no attack.

You can make a chart for the public IP address resource. In this chart, include the Packet Count (number of packets), Byte Count (amount of data), and Syn Count (number of synchronization packets) metrics. This will show you the sum of traffic.

> To make a fair comparison, you need to convert the data to packets-per-second. You can do this by dividing the number you see by 60, as the data represents the number of packets, bytes, or SYN packets collected over 60 seconds. For example, if you have 91,000 packets collected over 60 seconds, divide 91,000 by 60 to get approximately 1,500 packets-per-second (pps).
