Microsoft Exchange Trace Logs

The Microsoft Exchange Trace Logs Source collects email trace logs from the Office 365 reporting web service via the MessageTrace report under “Exchange reports”. Specific API reference information can be found here.

note

This Source is available in the Fed deployment.

States

A Microsoft Exchange Trace Logs Source tracks errors, reports its health, and start-up progress. You’re informed, in real-time, if the Source is having trouble connecting, if there's an error requiring user action, or if it is healthy and collecting by utilizing Health Events.

A Microsoft Exchange Trace Logs Source goes through the following states when created:

  1. Pending. Once the Source is submitted, it is validated, stored, and placed in a Pending state.
  2. Started. A collection task is created on the Hosted Collector.
  3. Initialized. The task configuration is complete in Sumo Logic.
  4. Authenticated. The Source successfully authenticated with Microsoft.
  5. Collecting. The Source is actively collecting data from Microsoft.

If the Source has any issues during any one of these states, it is placed in an Error state. When you delete the Source, it is placed in a Stopping state. When it has successfully stopped, it is deleted from your Hosted Collector. On the Collection page, the Health and Status for Sources is displayed. Use Health Events to investigate issues with collection. Hover your mouse over the status icon to view a tooltip with a count of the detected errors and warnings. You can click on the status icon to open a Health Events panel with details on each detected issue.

Set up Access in Azure

This source requires you to register an application within Azure Active Directory, generate a client secret, give permissions and generate an Oauth 2.0 authorization code. Follow the directions below within your Azure environment.

Register into Azure Application

An Azure application with specific permissions is required for Sumo Logic to access your Exchange Trace logs from Office 365. You need a subscription to Office 365 and a subscription to Azure that has been associated with your Office 365 subscription to set up this collection.

  1. Sign in to your Azure Portal with your administrator account at https://portal.azure.com
  2. Use the left navigation pane (might be hidden under the menu icon) and select Azure Active Directory.

Oauth 2.0 Generate Authorization Code

note

This authorization code will expire within 1 hour. Set up your Sumo Logic source before it expires.

  1. In a browser where you are already authenticated to your Azure portal, navigate to the URL below, but replace {{client_id}} with your Application (client) ID from the earlier steps.
https://login.windows.net/common/oauth2/authorize?response_type=code&resource=https://outlook.office365.com&client_id={{client_id}}&redirect_uri=https://localhost
  1. If successful, you will be redirected to a blank page with code and session_state as URL parameters. Write down the code value as this is your Oauth 2.0 authorization code you will use to configure the Sumo Logic C2C. This code is over 700 characters in length. Be careful to not copy the &session_state= at the end of the code. See below for an example:
https://localhost/?code={{REDACTED_AUTHORIZATION_CODE}}&session_state=50efb7a9-7678-4186-8b5b-abbb16d7b1ca#

Create a Microsoft Exchange Trace Logs Source

When you create a Microsoft Exchange Trace Logs Source, you add it to a Hosted Collector. Before creating the Source, identify the Hosted Collector you want to use or create a new Hosted Collector. For instructions, see Configure a Hosted Collector.

To configure a Microsoft Exchange Trace Logs Source:

  1. In Sumo Logic, select Manage Data > Collection > Collection
  2. On the Collectors page, click Add Source next to a Hosted Collector.
  3. Select MS Exchange Trace Logs.
    ms-exchange-icon.png
  4. Enter a Name for the Source. The description is optional.
    ms-exchange-schema-ui.png
  5. (Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called _sourceCategory.
  6. (Optional) Fields. Click the +Add Field link to define the fields you want to associate, each field needs a name (key) and value.
    • green check circle.png A green circle with a check mark is shown when the field exists in the Fields table schema.
    • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist in the Fields table schema. In this case, an option to automatically add the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema it is ignored, known as dropped.
  7. Application (client) ID. Enter your client ID from your Azure Application. This should be a Globally Unique Identifier aka GUID.
  8. Directory (tenant) ID. Enter your tenant ID from your Azure Application. This should be a Globally Unique Identifier aka GUID.
  9. Secret. Enter your client secret generated within your Azure Application.
  10. Oauth 2.0 Authorization Code Enter a valid authorization code. They expire within 1 hour of creation. The Microsoft Exchange Trace Logs Source will use this temporary code to automatically generate and rotate your API tokens for accessing the data.
  11. Polling Interval Seconds. We recommend leaving this to its defaults. This value controls how often the Microsoft Exchange Trace Logs Source polls the the Microsoft APIs for new data.
  12. Collection Time Offset. Use this value to offset the collection in the past by some amount of time. Microsoft claims data can be missing from the API within the last 24 hours. Set this to 86400 seconds aka 24 hours to help guarantee more complete results or reduce it if you are looking for more real time, but potentially incomplete data.
  13. When you are finished configuring the Source, click Submit.

Error types

When Sumo Logic detects an issue, it is tracked by Health Events. The following table shows the three possible error types. It also tells the reason the error occurred, if the Source attempts to retry, and the name of the event log in the Health Event Index.

TypeReasonRetriesRetry BehaviorHealth Event Name
ThirdPartyConfigNormally due to an invalid configuration. You'll need to review your Source configuration and make an update.No retries are attempted until the Source is updated.Not applicableThirdPartyConfigError
ThirdPartyGenericNormally due to an error communicating with the third party service APIs.YesThe Source will retry for up to 90 minutes, after which it quits.ThirdPartyGenericError
FirstPartyGenericNormally due to an error communicating with the internal Sumo Logic APIs.YesThe Source will retry for up to 90 minutes, after which it quits.FirstPartyGenericError
