Checkmk Werk 14533: azure agent: handle graph client errors gracefully

ID: 14533 Title: azure agent: handle graph client errors gracefully Component: agents Level: 1 Class: Bug fix Version: 2.2.0i1 The graph client API calls require some optional permissions so we are handling these permissions errors by notifying the user of the issue but by keeping the state to OK since it is a legit state. The section that is impacted is the "azure_ad" one. The message currently displayed is "Graph client: Insufficient privileges to complete the operation." and the permission that is currently needed is the Graph permission "Directory.Read.All" that requires admin consent. That permission needs to be granted to the check mk app created in Azure during the setup of checkmk Azure monitoring.
