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.

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. From here we use a take , to grab 20 random rows just to keep this result set small for the demo. A project follows, to reduce the columns we want. Finally is our sort operator. It will sort our output first by the Computer column, then by the TimeGenerated.

Description : Changing the aggregation function given to the summarize operator changes the aggregation method.

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.

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. The output column names are generated automatically, based on the arguments to the function. To assign different names to the output columns, use the following syntax By default, null values are put last in the sorted array.

Description : This query can be used to select one or more columns to show exclusively in the results and rename the column s. 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. Description : The top operator is used to sort records by the column value specified in the by argument. Description : Use the join operator to join Heartbeat table to syslog table to get a count of events per computer. Description : The search operator can generate many results, which affects performance. 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. Log in now. Reasons for failure vary, but for example, an unusual CallerIpAddress may indicate a security breach. Description : Changing the aggregation function given to the summarize operator changes the aggregation method.

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

In this post we saw how to sort your query results using the sort operator. AzureDiagnostics distinct Category. Default for desc is nulls last. Event summarize count by Computer. Search records for the past 1. Description : This query shows how to rename one or more columns in the results. This query allows you to see what operations have been performed on each resource, organized by provider. The where keyword, followed by a boolean expression tells Kusto to return only rows for which that expression is true. Alert where TimeGenerated between datetime " ".. Description : The datetime type returned by the datetime function is treated in UTC time. Use the where clause to filter the rows returned by a query. 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. Piping multiple search operators or filtering search operator results by where will result in a large result set being generated by the previous search operator for intermediate processing.
