In response to customer feedback, Amazon OpenSearch Service has introduced new administrative options, empowering customers to have more control over the automated mitigation actions.

3. Introducing New Administrative Options¶

With the new administrative options, customers can now restart the OpenSearch process on a node or restart an entire node as needed. These options provide users with greater control over their OpenSearch clusters, giving them the ability to initiate corrective actions if any issues arise.

Restarting the OpenSearch Process on a Node¶

Restarting the OpenSearch process on a node allows for the remediation of issues specific to that node. By initiating a restart, the problematic node can be refreshed, improving its performance and potentially resolving any anomalies. The process of restarting the OpenSearch process on a node involves gracefully stopping the node, performing necessary recovery actions, and then rejoining the cluster.

Restarting a Node¶

In situations where restarting the OpenSearch process on a node is not sufficient, customers can choose to restart the entire node. Restarting a node involves stopping and restarting all the processes running on that node, effectively resetting it to a clean state. This can be useful when a node is experiencing persistent issues that cannot be resolved through a simple process restart.

4. How to Control Automated Mitigation Actions¶

Customers can trigger the new administrative options through various interfaces, including the AWS Console, command line interface (CLI), or the AWS SDK. This flexibility ensures that users can integrate these options into their existing workflows and automate administrative actions as required.
