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". You cannot specify wildcard characters to search for similar values, such as HTTP error codes or CIDR IP address ranges.String values must be enclosed in quotation marks.The IN function returns TRUE if one of the values in the list matches a value in the field you specify.The Splunk documentation calls it the "in function".Īnd the syntax and usage are slightly different than with the search command. To use IN with the eval and where commands, you must use IN as an eval function. Using IN with the eval and where commands With the eval and where commands, it is implemented as the "IN function". With the search command this capability is referred to as the "IN operator". This search looks at the error_code field in your events and returns any event with a code that begins with 40. You can also use a wildcard in the value list to search for similar values. Note: The IN operator must be in uppercase. īecause the search command is implied at the beginning of a search string, all you need to specify is the field name and a list of values. With the IN operator, you can specify the field and a list of values. One of the best improvements made to the search command is the IN operator. error_code=400 OR error_code=402 OR error_code=404 OR error_code=406. You had to specify each field-value pair as a separate OR condition. But that's exactly what you had to do before version 6.6.0. It is really tedious to have to type field-value pair after field-value pair just to search for a list of values in the same field. Thank you Splunk!įor example, suppose in the "error_code" field that you want to locate only the codes 400, 402, 404, and 406. Searching for different values in the same field has been made easier.
