![]() ![]() In Kusto, this setting is predefined as part of the table structure. Kusto logs have the concept of a table, which has columns. ![]() Splunk doesn't expose the concept of event metadata to the search language. Both implementations allow unions and joining across these partitions. This setting directly affects the performance of queries and the cost of the deployment.Īllows logical separation of the data. Splunk doesn't.Ĭontrols the period and caching level for the data. Kusto allows arbitrary cross-cluster queries. The following table compares concepts and data structures between Splunk and Kusto logs: Concept Direct comparisons are made between the two to highlight key differences and similarities, so you can build on your existing knowledge. You can save this search as a dashboard panel or a report.This article is intended to assist users who are familiar with Splunk learn the Kusto Query Language to write log queries with Kusto. Switch to the Visualization tab and change the chart type to Pie Chart. You can also show the results in a chart. The results appear on the Statistics tab and show the counts for how many events have Purchase Related activity and how many have Other types of activity. The stats command counts the Purchase Related and Other values in the activity field.If the action field in an event contains any other value, the value Other is placed in the activity field.If the action field in an event contains the value addtocart or purchase, the value Purchase Related is placed in the activity field.The eval command creates a new field called activity.| eval activity=if(IN(action, "addtocart","purchase"),"Purchase Related","Other") Then the stats command performs a calculation. In the following example, the IN function is used with the IF function to evaluate the action field. We'll use the access.log file that is included with the Search Tutorial data. Let's go through an example where you can use the IN function as the first parameter for the IF function. The eval command cannot accept Boolean values, you must use the IN function inside another function that can process the Boolean values returned by the IN function. Using the IN function with the eval command is different than using IN with the where command. Because the codes are string values (not numeric values), you must enclose each value in quotation marks. The values in the status field are HTTP status codes. The following example uses the where command to return IN=TRUE if one of the values in the status field matches one of the values in the list. ![]() Let's start with the where command because it is fairly straight-forward. The IN function is shown in this blog in uppercase in the syntax and examples for clarity. Note: The IN function, unlike the IN operator, can be specified in upper or lowercase. | eval new_field=if(IN(field,"value1","value2".
