Like most query languages, the Kusto Query Language as the ability to sort the output.

T sort by column [ asc desc ] [ nulls first nulls last ] [ , Learn more about syntax conventions. A copy of the input table sorted in either ascending or descending order based on the provided column. The following example shows storm events by state in alphabetical order with the most recent storms in each state appearing first. 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. If multiple conditions need to be specified, they should be included in a single search operator condition.

For the examples in this article, we will use a table created with the following ADX commands:, kusto sort. In case of a tie for the first expression in the order by list, the output will be sorted by the second expression and so kusto sort. Description : Count the number of events collected per computer, aggregated into 1 hour time buckets.

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. You take your query, and pipe the output into the sort operator. After the by you simply list the column or columns to sort by. Here we pipe our Perf table into two where clauses to first reduce the output to the last 15 minutes using ago , then further reduce for only rows with a CounterName of Avg.

Description : This query shows how to rename one or more columns in the results. Description : When checking logs output by Azure services for troubleshooting, etc. This can be used to check for operations from unintended users or locations. By default, sorting is in descending order. Description : This query can be used to select columns to be shown in the output. The order by clause sorts the output of a query. Default is desc , high to low. 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. Alert where TimeGenerated between now - 3 d.. The type of the column values must be numeric, date, time or string. Description : Since there are quite a few different types of metrics, it is helpful to use the information of the resource provider from which they are generated when listing them. 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.

This is one of those situations, again, where it becomes personal preference which one to use.

In terms of syntax, it makes no difference whether you use desc or not, as descending order is the default. You can check the change work and see if any changes have been made to unnecessary resources. For this reason, KQL is almost always used to return a dataset - a collection of rows and columns that provide insights into your data. Using project-away to remove columns. Variables can be used to make the query easy to modify, easy to reuse, and easy to understand. Display 10 records in the AzureMetrics table AzureMetrics take You can use the between and datetime functions in combination for a TimeGenerated column to limit the time range. Using Project and an expression to create columns. Description : Since there are quite a few different types of metrics, it is helpful to use the information of the resource provider from which they are generated when listing them.
