Getting Rebalance Reason Codes
When a service in the cluster needs to be rebalanced, you can retrieve the reason for the rebalance using the 'GET /pools/default' method.
Description
At any point that the service needs rebalancing, you can use this method to obtain a detailed description of the reasons that the rebalance is required.
The reasons are returned in the servicesNeedRebalance array.
Each entry gives a reason code, such as service_not_balanced (the service isn’t balanced), and lists the services to which it applies.
| The service returns the reason code only if a rebalance is required. |
Response
On success, the response code 200 OK is given, and one or more reason codes are given in the returned message.
