Office 365 Exchange Online Monitoring

Prerequisites

• Opsview Monitor Version 6.0.0 (released 07 September 2018) or newer. Check Opsview Release Notes for the latest version of Opsview Monitor.

Known Issues

• As of the time of development, an issue exists with Microsoft's Graph API HTTP 429 Too Many Requests responses. These are received when too many requests are made in a short period of time. The issue lies in that the Retry-After value in the header of the response is always 86 which inhibits us from using this value to know when to retry. As a result, the checks using this API will wait for 5 seconds before retrying, up to a maximum of 5 times.

Setup Office 365 for Monitoring

To monitor your Office 365 environment, you will need to retrieve the following credentials, which will allow Opsview access to the metrics for your Office 365 Subscription:

• Tenant/Directory ID
• Client/Application ID
• Secret Key

Follow the steps below to retrieve this information.

Step 1: Find the Tenant ID

The Tenant/Directory ID can be found in the Azure Active Directory under the Properties section from the Azure dashboard.

Step 2: Find the Client/Application ID for your application

You need to create and register your application if you haven't already. Use the following documentation from Microsoft: Create an Azure Active Directory application

The Client/Application ID can be found in Azure Active Directory under the App registrations section from the Azure dashboard.

Step 3: Generate the Secret Key for your application

You will need to create a Secret Key for your application, once this has been created its value will be hidden so save the value during creation.

To create the Secret Key, select your application from the list, select the Settings within your application and then select the Keys option.

There you can create a new key by adding the description and expiration period and the value will be generated.

Step 4: Add Required Permissions

The appropriate permissions for the APIs used by these Office365 Host-Templates need to be added in Azure. From the same settings menu as above, go to Required Permissions under API ACCESS. Click Add, select the API and then choose the permissions for that API based on the table below.

API	Application Permissions	Delegated Permissions
Microsoft Graph	Read all usage reports Read your organization’s security events	Read all usage reports Read your organization’s security events

Setup and Configuration

Step 1: Add the Host Template
