Access Microsoft Graph activity logs

Microsoft Graph activity logs are an audit trail of all HTTP requests that the Microsoft Graph service received and processed for a tenant. Tenant administrators can enable the collection and configure downstream destinations for these logs using diagnostic settings in Azure Monitor. The logs are stored in Log Analytics for analysis, and you can export them to Azure Storage for long-term storage, or stream with Azure Event Hubs to external SIEM tools for alerting, analysis, or archival.

All logs for API requests made from line of business applications, API clients, SDKs, and by Microsoft applications like Outlook, Microsoft Teams, or the Microsoft Entra admin center are available.

This service is available in the following national cloud deployments.

To access the Microsoft Graph activity logs, you need the following privileges.

  • A Microsoft Entra ID P1 or P2 tenant license in your tenant.
  • An administrator with one of the following Microsoft Entra administrator roles listed in the order of least to most privileged role.
    • Security Administrator – To configure diagnostic settings
    • Global Administrator – To configure diagnostic settings
  • An Azure subscription with one of the following log destinations are configured, and permissions to access data in the corresponding log destinations.
    • An Azure Log Analytics workspace to send logs to Azure Monitor
    • An Azure Storage Account for which you have List Keys permissions
    • An Azure Event Hubs namespace to integrate with third-party solutions

What data is available in the Microsoft Graph activity logs?

The following data relating to API requests is available for Microsoft Graph activity logs on the Logs Analytics interface.

Column Type Description
AadTenantId string The Azure AD tenant ID.

Wids string Denotes the tenant-wide roles assigned to this user.

Common use cases for Microsoft Graph activity logs

  • Get full visibility into the transactions made by applications and other API clients that you have consented to in the tenant.
  • Identify the activities that a compromised user account conducted in your tenant.
  • Build detections and behavioral analysis to identify suspicious or anomalous use of Microsoft Graph APIs.
  • Investigate unexpected or suspicious privileged assignment of application permissions.
  • Identify problematic or unexpected behaviors for client applications such as extreme call volumes.
  • Correlate Microsoft Graph requests made by a user or app with sign-in information.

Configure to receive the Microsoft Graph activity logs

You can configure to stream the logs through the Diagnostic Setting in the Azure portal or through Azure Resource Manager APIs. For more information, see the guidance in the following articles:

The following articles guide you to configure the storage destinations:

Cost planning estimates

If you already have a Microsoft Entra ID P1 license, you need an Azure subscription to set up the Log Analytics workspace, Storage account, or Event Hubs. The Azure subscription comes at no cost, but you have to pay to utilize Azure resources.

The amount of data logged and, thus, the cost incurred, can vary significantly depending on the tenant size and the applications in your tenant that interact with Microsoft Graph APIs. The following table provides some estimates for log data size to aid the price calculation. Use these estimations for general consideration only.

Users in tenant Storage GiB/month Event Hubs Messages/month Azure Monitor Logs GiB/month
1000 14 62K 15
100000 1000 4.8M 1200

See the following pricing calculations for respective services:

Cost reduction for Log Analytics

If you're ingesting the logs to a Log Analytics Workspace but are only interested in logs filtered by a criteria, such as omitting certain columns or rows, you can partially reduce costs by applying a workspace transformation on the Microsoft Graph Activity Logs table. To find out more about workspace transformations, how it affects ingestion costs, and how to apply a transformation to your Microsoft Graph Activity Logs, see Data collection transformations in Azure Monitor.

An alternative approach to reduce Log Analytics cost is to switch to the Basic log data plan which lowers the bills by providing reduced capabilities. For more information, see Set a table's log data plan to Basic or Analytics.

Azure Monitor Logs query examples

If you send Microsoft Graph activity logs to a Log Analytics workspace, you can query the logs using Kusto Query Language (KQL). For more information about queries in Log Analytics Workspace, see Analyze Microsoft Entra activity logs with Log Analytics. You can use these queries for data exploration, to build alert rules, build Azure dashboards, or integrate into your custom applications using the Azure Monitor Logs API or Query SDK.

The following Kusto query identifies the top 20 entities making requests to groups resources that are failing due to authorization:

| where TimeGenerated >= ago(3d)
| where ResponseStatusCode == 401 or ResponseStatusCode == 403 
| where RequestUri contains "/groups"
| summarize UniqueRequests=count_distinct(RequestId) by AppId, ServicePrincipalId, UserId
| sort by UniqueRequests desc
| limit 20

The following Kusto query identifies resources queried or modified by potentially risky users:

| where TimeGenerated > ago(30d)
| join AADRiskyUsers on $left.UserId == $right.Id
| extend resourcePath = replace_string(replace_string(replace_regex(tostring(parse_url(RequestUri).Path), @'(\/)+','/'),'v1.0/',''),'beta/','')
| summarize RequestCount=dcount(RequestId) by UserId, RiskState, resourcePath, RequestMethod, ResponseStatusCode

The following Kusto query allows you to correlate the Microsoft Graph activity logs and sign-in logs. Activity logs from Microsoft applications may not all have matching sign in log entries. For more information, see Sign-in logs known limitations.

| where TimeGenerated > ago(7d)
| join kind=leftouter (union SigninLogs, AADNonInteractiveUserSignInLogs, AADServicePrincipalSignInLogs, AADManagedIdentitySignInLogs, ADFSSignInLogs
    | where TimeGenerated > ago(7d))
    on $left.SignInActivityId == $right.UniqueTokenIdentifier

The following Kusto query identifies apps that are getting throttled:

| where TimeGenerated > ago(3d) 
| where ResponseStatusCode == 429 
| extend path = replace_string(replace_string(replace_regex(tostring(parse_url(RequestUri).Path), @'(\/)+','//'),'v1.0/',''),'beta/','') 
| extend UriSegments =  extract_all(@'\/([A-z2]+|\$batch)($|\/|\(|\$)',dynamic([1]),tolower(path)) 
| extend OperationResource = strcat_array(UriSegments,'/')| summarize RateLimitedCount=count() by AppId, OperationResource, RequestMethod 
| sort by RateLimitedCount desc 
| limit 100 

The following query allows you to render a time-series chart:

| where TimeGenerated  between (ago(3d) .. ago(1h))  
| summarize EventCount = count() by bin(TimeGenerated, 10m) 
| render timechart

  • The Microsoft Graph activity logs feature allows the tenant administrators to collect logs for the resource tenant. This feature doesn't allow you to see the activities of a multitenant application in another tenant.
  • You can't filter Microsoft Graph activity logs through diagnostic settings in Azure Monitor. However, options are available to reduce costs in Azure Log Analytics Workspace. For more information, see Workspace transformation.
  • In most regions, the events will be available delivered to the configuration destination within 30 minutes. In less common cases, some events might take up to 2 hours to be delivered to the destination.
