The alerting feature notifies you when data from one or more OpenSearch indices meets certain conditions. For example, you might want to notify a Slack channel if your application logs more than five HTTP 503 errors in one hour, or you might want to page a developer if no new documents have been indexed in the past 20 minutes.
To get started, choose Alerting in OpenSearch Dashboards.
