Chapter 28. Events

28.1. Overview

Events in OpenShift Enterprise are modeled based on events that happen to API objects in an OpenShift Enterprise cluster. Events allow OpenShift Enterprise to record information about real-world events in a resource-agnostic manner. They also allow developers and administrators to consume information about system components in a unified way.

28.2. Viewing Events with the CLI

You can get a list of events in a given project using the following command:

$ oc get events [-n <project>]

28.3. Viewing Events in the Console

You can see events in your project from the web console from the BrowseEvents page. Many other objects, such as pods and deployments, have their own Events tab as well, which shows events related to that object.
