In previous versions of AEM administrators needed to look at several locations in order to get a full picture of the AEM instance. The System Overview aims to solve this by providing a high level view of the configuration, hardware, and health of the AEM instance all from a single dashboard.

  1. The System Overview can be accessed from: AEM Start > Tools > Operations > System Overview 

    Directly at <server-host>/libs/granite/operations/content/systemoverview.html

  2. The information from the System Overview can be exported by clicking the download button. The information is also exposed via the following REST endpoint:

    <server-host>/libs/granite/operations/content/systemoverview/export.json

  3. Below is a sample output of the JSON that is exported from the System Overview:
