Enabling Overload Control for a Cluster

Scenario

After overload control is enabled, the number of simultaneous requests is dynamically regulated according to the resource pressure on the master nodes. This ensures that both the nodes and the cluster remain accessible.

Notes and Constraints

The cluster version must be 1.23 or later.

Enabling Overload Control

Method 1: Enabling it when creating a cluster

When creating a cluster of v1.23 or later, you can enable overload control during the cluster creation.

Method 2: Enabling it in an existing cluster

1. Log in to the CCE console and click the name of an existing cluster whose version is v1.23 or later.
2. On the Overview page, check the master node information. If overload control is not enabled, a message will be displayed. You can click Enable to enable the function.

Disabling Cluster Overload Control

1. Log in to the CCE console and click the name of an existing cluster whose version is v1.23 or later.
2. In the navigation pane, choose Settings.
3. On the Cluster Access tab page, disable overload control.
4. Click OK.
