title: Viewing system event information in OpenShift Container Platform clusters

# Viewing system event information in OpenShift Container Platform clusters {#nodes-containers-events}

You can view events in OpenShift Container Platform, which are based on events that happen to API objects in an OpenShift Container Platform cluster.

## Understanding events {#nodes-containers-events-about_nodes-containers-events}

Review the following information to learn how OpenShift Container Platform uses *events* to record information about real-world events in a resource-agnostic manner. Events also allow developers and administrators to consume information about system components in a unified way.

## Viewing events using the CLI {#nodes-containers-events-viewing-cli_nodes-containers-events}

You can get a list of events in a given project by using the CLI.

**Procedure**

- View events in a project by using a command similar to the following:

  ```terminal
  $ oc get events [-n <project>]
  ```

  where:

  `project`
  :   Specifies the name of the project.

  For example:

  ```terminal
  $ oc get events -n openshift-config
  ```

  ```terminal {title="Example output"}

  #...
  ```
- View events in your project from the OpenShift Container Platform console:

  1. Launch the OpenShift Container Platform console.
  2. Click **Home** → **Events** and select your project.
  3. Move to resource that you want to see events. For example: **Home** → **Projects** → <project-name> → <resource-name>.

     Many objects, such as pods and deployments, also have an **Events** tab, which shows events related to that object.
