Log queries help you to fully leverage the value of the data collected in Azure Monitor Logs. A powerful query language allows you to join data from multiple tables, aggregate large sets of data, and perform complex operations with minimal code. Virtually any question can be answered and analysis performed as long as the supporting data has been collected, and you understand how to construct the right query.

Some features in Azure Monitor such as insights and solutions process log data without exposing you to the underlying queries. To fully leverage other features of Azure Monitor, you should understand how queries are constructed and how you can use them to interactively analyze data in Azure Monitor Logs. Use this article as a starting point to learning about log queries in Azure Monitor.

It answers common questions and provides links to other documentation that provides further details and lessons. Once you have the basics down, walk through multiple lessons using either your own data or data from our demo environment starting with:. This is a rich language designed to be easy to read and author, and you should be able to start using it with minimal guidance. See Get started with log queries in Azure Monitor for a quick walkthrough of the language using data from Azure Monitor Logs.

All data collected in Azure Monitor Logs is available to retrieve and analyze in log queries. Different data sources will write their data to different tables, but you can include multiple tables in a single query to analyze data across multiple sources. When you build a query, you start by determining which tables have the data that you're looking for, so you should have at least a basic understanding of how data in Azure Monitor Logs is structured.

See Structure of Azure Monitor Logs for an explanation of how the data is structured. For more complex analysis, you might retrieve data from multiple tables using a join to analyze the results together. Even if you aren't familiar with KQL, you should be able to at least figure out the basic logic being used by these queries. They start with the name of a table and then add multiple commands to filter and process that data.

A query can use any number of commands, and you can write more complex queries as you become familiar with the different KQL commands available. See Get started with log queries in Azure Monitor for a tutorial on log queries that introduces the language and common functions.

Log Analytics is the primary tool in the Azure portal for writing log queries and interactively analyzing their results.Azure PowerShell supports several authentication methods.

The easiest way to get started is with Azure Cloud Shellwhich automatically logs you in. With a local install, you can sign in interactively through your browser. When writing scripts for automation, the recommended approach is to use a service principal with the necessary permissions.

When you restrict sign-in permissions as much as possible for your use case, you help keep your Azure resources secure. After signing in, commands are run against your default subscription.

To change your active subscription for a session, use the Set-AzContext cmdlet. Your credentials are shared among multiple PowerShell sessions as long as you remain signed in. For more information, see the article on Persistent Credentials.

To sign in interactively, use the Connect-AzAccount cmdlet. When run, this cmdlet will present a token string. Your PowerShell session will be authenticated to connect to Azure. If you use credential authorization for automation purposes, instead create a service principal. Service principals are non-interactive Azure accounts. Like other user accounts, their permissions are managed with Azure Active Directory.

By granting a service principal only the permissions it needs, your automation scripts stay secure. To sign in with a service principal, use the -ServicePrincipal argument with the Connect-AzAccount cmdlet. You'll also need the service principal's application ID, sign-in credentials, and the tenant ID associate with the service principal. How you sign in with a service principal will depend on whether it's configured for password-based or certificate-based authentication. To get the service principal's credentials as the appropriate object, use the Get-Credential cmdlet.

This cmdlet will present a prompt for a username and password. Use the service principal ID for the username. Make sure that you use good password storage practices when automating service principal connections.

Certificate-based authentication requires that Azure PowerShell can retrieve information from a local certificate store based on a certificate thumbprint. When using a service principal instead of a registered application, add the -ServicePrincipal argument and provide the service principal's Application ID as the -ApplicationId parameter's value. In PowerShell 5. For PowerShell Core 6. The following scripts show you how to import an existing certificate into the certificate store accessible by PowerShell.

Managed identities are a feature of Azure Active Directory. Managed identities are service principals assigned to resources that run in Azure. You can use a managed identity service principal for sign-in, and acquire an app-only access token to access other resources. Managed identities are only available on resources running in an Azure cloud. This command connects using the managed identity of the host environment.The sign-in activity report is available in all editions of Azure AD.

If you want to access the sign-in data using an API, your tenant must have an Azure Active Directory Premium license associated with it. Under Monitoringselect Sign-ins to open the Sign-ins report. The sign-ins report only displays the interactive sign-ins, that is, sign-ins where a user manually signs in using their username and password. Non-interactive sign-ins, such as service-to-service authentication, are not displayed in the sign-ins report.

The Columns dialog gives you access to the selectable attributes. In a sign-in report, you can't have fields that have more than one value for a given sign-in request as column. This is, for example, true for authentication details, conditional access data and network location.

Operating system - The operating system running on the device used sign-on to your tenant.

Device browser - If the connection was initiated from a browser, this field enables you to filter by browser name. Success : One or more conditional access policies applied to the user and application but not necessarily the other conditions during sign-in.

Failure : One or more conditional access policies applied and was not satisfied during sign-in. Start with download the sign-ins data if you want to work with it outside the Azure portal. The number of records you can download is constrained by the Azure Active Directory report retention policies.

The user sign-in graph in the Identity security protection overview page shows weekly aggregations of sign-ins. The default for the time period is 30 days. When you click on a day in the sign-in graph, you get an overview of the sign-in activities for this day. IP addresses are issued in such a way that there is no definitive connection between an IP address and where the computer with that address is physically located.

Mapping IP addresses is complicated by the fact that mobile providers and VPNs issue IP addresses from central pools that are often very far from where the client device is actually used.
