Configure an Alert each OpenSearch Index dos not receive logs over 30m

Hello,
I have 5 different indexes.
I would like to configure an Alert each OpenSearch Index dos not receive logs over 30m.
how can i do that?

As i know OpenSearch does not have a built-in Watcher or alerting functionality similar to the one in Elasticsearch, maybe i’m wrong.

hank you for the assistance.

@AndreyB It does. The plugin is called Alerting and Watchers are called Monitors.

Thank you Pablo.
I will read that.
