- When you add a VM NIC to a load balancer in ZStack Cloud, you can set the weight of the backend
server by adding the balancerWeight option to
SystemTags.
- Format of the balancerWeight option:
balancerWeight::{nicUuid}::{weight}
. Here, weight is the weight of the backend server. Weight range: 0-100, integer. Default value: 100. - Example:
balancerWeight::{"c44007641c9040c6b2587e19b1b3e2b0"}::{100}
