Updated at：2025-10-16
Baidu AI Cloud Network Probe is a service to monitor the quality of VPC network connectivity and supports Ping detection for various resources such as Baidu Cloud Compute, NAT gateway, VPN gateway, peering connections, dedicated gateway, and Cloud Smart Network. It tracks key metrics like latency and packet loss, enabling real-time evaluation of connection quality and instant notifications for connection failures.
Before Configuration, users should understand:
- A maximum of 50 network probe instances can be created within a VPC.
