Retrieving Auto-Failover Settings

Auto-failover settings are retrieved by means of the GET /settings/autoFailover HTTP method and URI.

HTTP method and URI

Retrieves auto-failover settings for a cluster. Auto-failover is a global setting, which applies to all nodes in the cluster. To read auto-failover settings, appropriate privileges are required.

GET /settings/autoFailover

Parameters include:

  • enabled. Indicates whether automatic failover is enabled (a value of true) or disabled (a value of false).

  • timeout. Returns an integer between 5 and 3600, which specifies the number of seconds set to elapse, after a node has become unavailable, before automatic failover is triggered.

  • count. This parameter represents how many sequential auto-failover events have occurred since the parameter was itself last reset, to a value of 0, through administrator intervention. The parameter’s default value is 0. Couchbase Server increments this value by 1 for every auto-failover event that occurs, up to the maximum count — an administrator-specified number whose highest-permitted value is 3. If sequential auto-failover events occur until the maximum count is reached, no further auto-failover is triggered until a parameter-reset is performed.

Syntax

Curl request syntax:

curl -u [admin]:[password] http://[localhost]:8091/settings/autoFailover

Example

Curl request example:

curl -u Administrator:password http://10.5.2.54:8091/settings/autoFailover

Response

If successful, execution returns the auto-failover settings for the cluster. For example:

{
  "enabled": true,
  "timeout": 72,
  "count": 0,
  "failoverOnDataDiskIssues": {
    "enabled": true,
    "timePeriod": 89
  },
    "failoverServerGroup": true,
    "maxCount": 2
}
