Orders the remaining arrays to match the reordered first array. Learn more about syntax conventions. Returns the same number of arrays as in the input, with the first array sorted in ascending order, and the remaining arrays ordered to match the reordered first array. Run the query.

By executing commands operators, functions that appear frequently in actual KQL usage situations from various angles and in various ways, the user is expected to learn the commands by hand. In KQL, as in any other programming language, each language element is given a name. Remembering these names is not mandatory, but it is a good thing to keep in mind in order to improve learning efficiency. The KQL on this page is intended to be run against this data. To search the Azure Monitor logs, you need to know what tables are in the workspace and what structure each table contains records. Here you will learn how to use basic operators to find tables that contain the information you are looking for, and how to examine the structure of the data contained in the tables you locate, using the most commonly used tables as the subject matter. Description : The search operator performs a search on all tables in the workspace if no table is specified. The search operator can be used when you do not know which table contains the data you want, or when you do not know if the data exists in the workspace in the first place. It should not be used too often for queries that are executed periodically, as it has a performance disadvantage when searching large amounts of data. It is also not available in some Kusto execution environments. Description : The search operator can generate many results, which affects performance.

Description : Use the render operator to draw a chart of the processor utilisation over time with aggregations into 1 hour averages, broken down by computer, kusto sort.

Like most query languages, the Kusto Query Language as the ability to sort the output. It works almost, but not quite, like you expect. This demo site has been provided by Microsoft and can be used to learn the Kusto Query Language at no cost to you. It describes the user interface in detail. Note that my output may not look exactly like yours when you run the sample queries for several reasons. Finally, Microsoft may make changes to both the user interface and the data structures between the time I write this and when you read it.

This tutorial is an introduction to the essential KQL operators used to access and analyze your data. For more specific guidance on how to query logs in Azure Monitor, see Get started with log queries. The examples in this tutorial use the StormEvents table, which is publicly available in the help cluster. To explore with your own data, create your own free cluster. Begin by using the count operator to find the number of storm records in the StormEvents table. Run the query. To get a sense of the data, use the take operator to view a sample of records. This operator returns a specified number of arbitrary rows from the table, which can be useful for previewing the general data structure and contents. The following table shows only 6 of the 22 returned columns.

This is one of those situations, again, where it becomes personal preference which one to use. In fact, when you read through the KQL reference doc it will tell you that…. You can Sort by multiple columns and each column by different directions. For example, replace the Order By line above with the following: order by TimeGenerated desc, Computer asc. The default view returned for data is descending order desc. If you are sorting by a data column that has null values empty records , those will be displayed first using the default order desc. Lastly, to continue to improve and hone your query knowledge — particularly for efficiency — the Top operator can be used to simplify our example. Plus, the Top operator is a great way to retrieve the most recent records instead of always relying on random samples. See what I did there? The Top operator is performing, essentially, the same operation as before, but it has simplified the query that it is required.

Note Null and NaN values are always grouped together. Description : Combining the summarize function with the bin function and the time function allows more flexible aggregation for dates. Using Project and an expression to create columns. Additional resources In this article. Loading Comments Description : The name of the performance counter for free disk space is FreeSpacePercentage. The return value of the datetime function can be obtained as type datetime. It describes the user interface in detail. Description : The now function accepts an offset of type timespan as an argument. Skip to main content. Yes No. By default, sorting is in descending order. Well in fact it is, since by default the sort operator sorts in descending order. AzureDiagnostics summarize count by ResourceProvider render piechart.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The following article describes how string terms are indexed, lists the string query operators, and gives tips for optimizing performance. Kusto indexes all columns, including columns of type string.

The type of the column values must be numeric, date, time or string. The order between null and NaN values is determined by the first and last property because nulls and NaNs don't have an ascending and descending order. Mixed Sorting The nice thing about placing the sort order after the column name is that you can set the sort order for each column independent of the other columns. Alert where TimeGenerated between now - 3 d.. Published by arcanecode. The first thing in a KQL query is the source of the data you are querying. Coming soon: Throughout we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. Which computers have the largest amount of disk space used? Use the where clause to filter the rows returned by a query. Show 10 records in the AzureActivity table AzureActivity take
