CountTimeout         int64   `json:"countTimeout"`

Configurations

in chassis.yaml file. You need to configure your micro service to send the data to Huaweicloud ServiceStage.

cse:
  monitor:
    client:
      serverUri: https://cse.cn-north-1.myhwclouds.com:443
      enable: true

Data Post

Every 2 sec data will be posted to monitoring server if serverUri is correct and enable is true
