View Azure activity logs
The Activity Log Analytics solution helps you analyze and search the Azure activity log across all your Azure subscriptions. The Azure Activity Log is a log that offers insights into the operations performed on resources in your subscriptions. The Activity Log was previously known as Audit Logs or Operational Logs since it reports events for your subscriptions.
Using the Activity Log, you can determine the what, who, and when for any write operations (PUT, POST, DELETE) made for the resources in your subscription. You can also understand the status of the operations and other relevant properties. The Activity Log does not include read (GET) operations or operations for resources that use the Classic deployment model.
When you connect your Azure activity logs to Log Analytics, you can:
- Analyze the activity logs with pre-defined views
- Analyze and search and activity logs from multiple Azure subscriptions
- Keep activity logs for longer than 90 days1
- Correlate activity logs with other Azure platform and application data
- See operational activities aggregated by status
- View trends of activities happening on each of your Azure services
- Report on authorization changes on all your Azure resources
- Identify outage or service health issues impacting your resources
- Use Log Search to correlate user activities, auto-scale operations, authorization changes, and service health to other logs or metrics from your environment
1By default, Log Analytics keeps your Azure activity logs for 90 days, even if you are on the Free tier. Or, if you have a workspace retention setting of less than 90 days. If your workspace has retention that is longer than 90 days, the activity logs are kept for the retention period of your workspace.
Log Analytics collects activity logs free of charge and stores the logs for 90 days free of charge. If you store logs for longer than 90 days, you will incur data retention charges for the data stored longer than 90 days.
When you're on the Free pricing tier, activity logs do not apply to your daily data consumption.
Unlike most other Log Analytics solutions, data isn't collected for activity logs by agents. All data used by the solution comes directly from Azure.

If you add the solution using the OMS portal, you'll see the following tile. Sign in to the Azure portal to connect an Azure subscription to your workspace.
Using the solution
When you add the Activity Log Analytics solution to your workspace, the Azure Activity Logs tile is added to your Overview dashboard. This tile displays a count of the number of Azure activity records for the Azure subscriptions that the solution has access to.
View Azure Activity logs
Click the Azure Activity Logs tile to open the Azure Activity Logs dashboard. The dashboard includes the blades in the following table. Each blade lists up to 10 items matching that blade's criteria for the specified scope and time range. You can run a log search that returns all records by clicking See all at the bottom of the blade or by clicking the blade header.
Activity log data only appears after you've configured your activity logs to go to the solution, so you can't view data before then.
