Kusto ai

A Kusto query is a read-only request to process data and return results. The request is stated in plain text, using a data-flow model designed to make the syntax easy to read, author, and automate.

The query uses schema entities that are organized in a hierarchy similar to SQL's: databases, tables, and columns. The query consists of a sequence of query statements, delimited by a semicolon ;with at least one statement being a tabular expression statement which is a statement that produces data arranged in a table-like mesh of columns and rows.

The query's tabular expression statements produce the results of the query. The syntax of the tabular expression statement has tabular data flow from one tabular query operator to another, starting with data source e. For example, the following Kusto query has a single statement, which is a tabular expression statement. The statement starts with a reference to a table called StormEvents the database that host this table abyss cast implicit here, and part of the connection information.

The data rows for that table are then filtered by the value of the StartTime column, and then filtered by the value of the State column. The query then returns the count of "surviving" rows.

You might find that using keyboard shortcuts enables you to perform operations faster than with the mouse. Take a look at this list of Kusto. Explorer keyboard shortcuts. Explorer keeps track of what settings are used per unique set of columns. So when columns are reordered or removed, the data view is saved and will be reused whenever the data with the same columns is retrieved.

To reset the view to its defaults, in the View tab, select Reset View. The left pane of Kusto. Explorer shows all the cluster connections that the client is configured with. For each cluster it shows the databases, tables, and attributes columns that they store.

Explorer supports controlling the Connection panel from the query window. This is very useful for scripts. For example, starting a script file with a command that instructs Kusto. As usual, you'll have to run each line using F5 or similar:. When adding a new connection, the default security model used is AAD-Federated security, in which authentication is done through the Azure Active Directory using the default AAD user experience.

In some cases, you might need finer control over the authentication parameters than is available in AAD. If so, it's possible to expand the "Advanced: Connection Strings" edit box and provide a valid Kusto connection string value.

For example, users who have presence in multiple AAD tenants sometimes need to use a particular "projection" of their identities to a specific AAD tenant.

The domain name of the user is not necessarily the same as that of the tenant hosting the cluster. Explorer tries to "guess" the severity or verbosity level of each row in the results pane and color it accordingly.

It does this by matching the distinct values of each column with a set of known patterns "Warning", "Error", and so on. Explorer has a powerful script mode which enables you to write, edit and run ad-hoc queries. Make sure you created the table with a schema which matches your file for example, using the.

Right-click the target database in the Connections paneland select Refreshso that your table appears. Right-click the target table in the Connections paneland select Import data from local files.

Only admins can add or drop authorized principals in their own scope. Right-click the target entity in the Connections paneland select Manage Authorized Principals.Kusto is a phenomenal tool.

I can gush about it, without boast, because I can take almost no credit for it. Kusto was already an incubation project when I inherited the team a couple of years ago and over those 2 years it has taken Microsoft by storm.

As you might imagine, Microsoft operates a whole lot of cloud services — certainly hundreds, maybe thousands. And many of those run at amazingly high scale.

Kusto Application Insights Analyticsis a near realtime log analytics platform for interactive data exploration that enables you to do amazing things. As of today, Kusto ingests over 1 trillion events and TB a day and growing rapidly — I predict over a PB a day within a few months of log data across hundreds of Microsoft cloud services.

And the engineers who use Kusto internally love it. Kusto allows an engineer to query through terabytes of data in seconds, and quickly refine queries until they find what they want. The Application Insights Analytics preview ingests any data the Application Insights SDK sends — built in or custom and allows you to query over it easily from a browser.

Let me show you a little Kusto. OK, that was really more of a usage scenario. It also enables you to easily explore that schema. For the moment, we have retention set to 8 days. Refer to this documentation on how sampling works in Application Insights. Please refer to analytics documentation on how to write queries for such sampled apps. In fact, based on the February telemetry, only about 1.

Almost 90 million of them were driven by automated tools people have written to mine Kusto data. The powerful and interactive query capability is awesome but the thing that truly blows people away is the performance over very large amounts of data. A year or so ago, the PowerBI team decided they needed a good log analytics solution. To be honest, they liked it very much. When we got Kusto to the point that it was ready, it took some arm twisting to get them to even be willing to consider switching.

We recently completed a Proof Of Concept and below is a picture from a cell phone : of a summary comparison slide the PowerBI team presented to their own org explaining why they need to switch to Kusto.

The difference is mind blowing. I encourage you to give it a try and let us know what you think.

Some of these are from internal teams and some are from external customers who have participated in the preview. They give you a flavor of how amazing the product is.

They are spontaneous compliments that people sent just because they were so excited. Learn about Azure DevOps. Learn about Azure DevOps Server. DevOps at Microsoft.Microsoft summarizes the Logic Apps like this…. Logic Apps provide a way to simplify and implement scalable integrations and workflows in the cloud.

It provides a visual designer to model and automate your process as a series of steps known as a workflow. There are many connectors across the cloud and on-premises to quickly integrate across services and protocols. I would like to share one example of such an integration between systems. As you know, Microsoft changed the Log Analytics backend to Kusto, which is the same system that is using Application Insights.

BUT there could be cases, where you want to insert custom data from AI to ALA on a regular schedule, which is not available through this connector. This is exactly what I want to show you in this blog post.

This is not a real world scenario, but gives you a pretty good idea how it works and how powerful it can be. This is a simple trigger scheduler which starts the workflow every 1 hour. You can go as low as seconds. First you need to connect to Application Insights…. After this configuration, you simply need to specify the query to run…. If I run the query itself it will return a simple table…. The tricky part is to get the data format for this action in the correct format JSON.

If you are trying to accomplish this using the Logic App designer it will be a bit tricky to do so. Instead we can switch to code view…. Once you start the workflow you can inspect the actual data and you will see what is passed to the next step….

Keep in mind in this example on each run we send the full stack of data to ALA. This is probably not what you want, instead you could modify the query, add filter options or different data modification actions to the workflow to massage your data.

You might have heard that Microsoft is switching to a semi-annual channel for Windows Server and System Center. If you have no clue what this is or what it means then read this post from June I am a big fan of Azure Monitor and Azure in general.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am trying to follow the instructions in Insights Preview where I can create custom telemetry.

I followed the instructions exactly. But maybe I've got it configured wrong. But when I add a new TelemetryClient I start getting those duplicate errors below.

The traditional correlation rules of a SIEM are not enough, they are lacking the full context of the attack and can only detect attacks that were seen before. This can result in false negatives and gaps in the environment. In addition, correlation rules require significant maintenance and customization since they may provide different results based on the customer environment.

Introducing Application Insights Analytics

Advanced Machine Learning capabilities that are built in into Azure Sentinel can detect indicative behaviors of a threat and helps security analysts to learn the expected behavior in their enterprise. In addition, Azure Sentinel provides out-of-the-box detection queries that leverage the Machine Learning capabilities of Kusto query language that can detect suspicious behaviors in such as abnormal traffic in firewall data, suspicious authentication patterns, and resource creation anomalies.

The queries can be found in the Azure Sentinel GitHub community. Below you can find three examples for detections leveraging built in Machine Learning capabilities to protect your environment. A typical organization may have many users and many applications using Azure Active Directory for authentication.

Some applications for example Office Exchange Online may have many more authentications than others say Visual Studio and thus dominate the data. Users may also have a different location profile depending on the application.

For example high location variability for email access may be expected, but less so for development activity associated with Visual Studio authentications. Resource creation in Azure is a normal operation in the environment.

Operations and IT teams frequently spin up environments and resources based on the organizational needs and requirements. Tracking anomalous resources creation or suspicious deployment activities in azure activity log can provide a lead to spot an execution technique done by an attacker.

Firewall traffic can be an additional indicator of a potential attack in the organization. The ability to establish a baseline that represents the usual firewall traffic behavior on a weekly or an hourly basis can help point out the anomalous increase in traffic. Using the built-in capabilities in the Log Analytics query language can point directly to the traffic anomaly and be investigated.
