Azure module

The azure module retrieves different types of log data from Azure. There are several requirements before using the module since the logs will actually be read from azure event hubs.

• the logs have to be exported first to the event hubs https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-create-kafka-enabled
• to export activity logs to event hubs users can follow the steps here https://docs.microsoft.com/en-us/azure/azure-monitor/platform/activity-log-export
• to export audit and sign-in logs to event hubs users can follow the steps here https://docs.microsoft.com/en-us/azure/active-directory/reports-monitoring/tutorial-azure-monitor-stream-logs-to-event-hub

The module contains the following filesets:

activitylogs

Will retrieve azure activity logs. Control-plane events on Azure Resource Manager resources. Activity logs provide insight into the operations that were performed on resources in your subscription. To learn more, refer to the Azure Activity log documentation.

platformlogs

Will retrieve azure platform logs. Platform logs provide detailed diagnostic and auditing information for Azure resources and the Azure platform they depend on. To learn more, refer to the Azure platform logs documentation.

signinlogs

Will retrieve azure Active Directory sign-in logs. The sign-ins report provides information about the usage of managed applications and user sign-in activities. To learn more, refer to the Azure sign-in logs documentation.

auditlogs

Will retrieve azure Active Directory audit logs. The audit logs provide traceability through logs for all changes done by various features within Azure AD. Examples of audit logs include changes made to any resources within Azure AD like adding or removing users, apps, groups, roles and policies. To learn more, refer to the Azure audit logs documentation.

eventhub

string Is the fully managed, real-time data ingestion service. Default value of insights-operational-logs for activitylogs, insights-logs-auditlogs for auditlogs, and insights-logs-signinlogs for signinlogs. It is recommended to use a separate eventhub for each log type as the field mappings of each log type are different.

consumer_group

string The publish/subscribe mechanism of Event Hubs is enabled through consumer groups. A consumer group is a view (state, position, or offset) of an entire event hub. Consumer groups enable multiple consuming applications to each have a separate view of the event stream, and to read the stream independently at their own pace and with their own offsets. Default value: $Default

connection_string

string The connection string required to communicate with Event Hubs, steps here https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-get-connection-string.

A Blob Storage account is required in order to store/retrieve/update the offset or state of the eventhub messages. This means that after stopping the filebeat azure module it can start back up at the spot that it stopped processing messages.

storage_account

string The name of the storage account the state/offsets will be stored and updated.

storage_account_key

string The storage account key, this key will be used to authorize access to data in your storage account.

resource_manager_endpoint

string Optional, by default we are using the azure public environment, to override, users can provide a specific resource manager endpoint in order to use a different azure environment. Ex: https://management.chinacloudapi.cn/ for azure ChinaCloud https://management.microsoftazure.de/ for azure GermanCloud https://management.azure.com/ for azure PublicCloud https://management.usgovcloudapi.net/ for azure USGovernmentCloud Users can also use this in case of a Hybrid Cloud model, where one may define their own endpoints.

When you run the module, it performs a few tasks under the hood:

• Sets the default paths to the log files (but don’t worry, you can override the defaults)
• Makes sure each multiline log event gets sent as a single event
• Uses an Elasticsearch ingest pipeline to parse and process the log lines, shaping the data into a structure suitable for visualizing in Kibana

The azure module comes with several predefined dashboards for general cloud overview, user activity and alerts. For example:
