After creating a health check instance, you also need to add a probe to the instance. Direct Connect probes collect link delay and packet loss data in real time by continuously sending ICMP packets from a specific source IP within the Virtual Private Cloud (VPC) to a specified destination IP on-premises.

Procedure

In the top menu bar, select your target region.

Select Health Check in the left-side navigation pane.

Click the target instance name, then click the Probe tab.

Click Add Probe and configure the probe based on the table below.

Parameter	Description	Example
Source configuration
VPC	Select the VPC where the probe is located.	vpc-01
Subnet	Select the subnet where the probe is located. Changes are not supported after selection. The source IP will be randomly assigned within the subnet. Please choose carefully.	subnet-01
Destination configuration
Destination configuration	Add the destination IP of the probe. IP address: Currently supports only IPv4 format. Protocol: Currently supports ICMP. Packet size: Set the packet size based on actual business requirements to allocate bandwidth resources reasonably. You can enter an integer in the range of 56 to 8500.	10.XX.XX.4\|ICMP\|56

Click Add to complete the action.
