sort command sorts all of the results by the specified fields. Results missing a given field are treated as having the smallest or largest possible value of that field if the order is descending or ascending, respectively.
If the first argument to the
sort command is a number, then at most that many results are returned, in order. If no number is specified, the default limit of 10000 is used. If the number 0 is specified, all of the results are returned. See the
count argument for more information.
sort [<count>] <sort-by-clause>... [desc]
- Syntax: ( - | + ) <sort-field>, ( - | + ) <sort-field> ...
- Description: List of fields to sort by and the sort order. Use a minus sign (-) for descending order and a plus sign (+) for ascending order. When specifying more than one field, separate the field names with commas. See Sort field options.
- Syntax: <int>
- Description: Specify the number of results to return from the sorted results. If no count is specified, the default limit of 10000 is used. If
0is specified, all results are returned.
- Default: 10000
- Syntax: d | desc
- Description: A trailing string that reverses the results.
Sort field options
- Syntax: <field> | auto(<field>) | str(<field>) | ip(<field>) | num(<field>)
- Description: Options you can specify with <sort-field>.
- Syntax: <string>
- Description: The name of field to sort.
- Syntax: auto(<field>)
- Description: Determine automatically how to sort the values of the field.
- Syntax: ip(<field>)
- Description: Interpret the values of the field as IP addresses.
- Syntax: num(<field>)
- Description: Interpret the values of the field as numbers.
- Syntax: str(<field>)
- Description: Interpret the values of the field as strings and order the values alphabetically.
sort tries to automatically determine what it is sorting. If the field takes on numeric values, the collating sequence is numeric. If the field takes on IP address values, the collating sequence is for IPs. Otherwise, the collating sequence is in lexicographical order. Some specific examples are:
- Alphabetic strings are sorted lexicographically.
- Punctuation strings are sorted lexicographically.
- Numeric data is sorted as you would expect for numbers and the sort order is specified as ascending or descending.
- Alphanumeric strings are sorted based on the data type of the first character. If the string starts with a number, the string is sorted numerically based on that number alone. Otherwise, strings are sorted lexicographically.
- Strings that are a combination of alphanumeric and punctuation characters are sorted the same way as alphanumeric strings.
In the default automatic mode for a field, the sort order is determined between each pair of values that are compared at any one time. This means that for some pairs of values, the order might be lexicographical, while for other pairs the order might be numerical. For example, if sorting in descending order: 10.1 > 9.1, but 10.1.a < 9.1.a.
Lexicographical order sorts items based on the values used to encode the items in computer memory. In Splunk software, this is almost always UTF-8 encoding, which is a superset of ASCII.
- Numbers are sorted before letters. Numbers are sorted based on the first digit. For example, the numbers 10, 9, 70, 100 are sorted lexicographically as 10, 100, 70, 9.
- Uppercase letters are sorted before lowercase letters.
- Symbols are not standard. Some symbols are sorted before numeric values. Other symbols are sorted before or after letters.
Sort results by "ip" value in ascending order and then by "url" value in descending order.
... | sort num(ip), -str(url)
Sort first 100 results in descending order of the "size" field and then by the "source" value in ascending order. This example specifies the type of data in each of the fields. The "size" field contains numbers and the "source" field contains strings.
... | sort 100 -num(size), +str(source)
Sort results by the "_time" field in ascending order and then by the "host" value in descending order.
... | sort _time, -host
Change the format of the event's time and sort the results in descending order by the Time field that is created with the
... | bin _time span=60m | eval Time=strftime(_time, "%m/%d %H:%M %Z") | stats avg(time_taken) AS AverageResponseTime BY Time | sort - Time
(Thanks to Splunk user Ayn for this example.)
Sort a table of results in a specific order, such as days of the week or months of the year, that is not lexicographical or numeric. For example, you have a search that produces the following table:
Sorting on the day field (Day) returns a table sorted alphabetically, which does not make much sense. Instead, you want to sort the table by the day of the week, Monday to Friday. To do this, you first need to create a field (sort_field) that defines the order. Then you can sort on this field.
... | eval wd=lower(Day) | eval sort_field=case(wd=="monday",1, wd=="tuesday",2, wd=="wednesday",3, wd=="thursday",4, wd=="friday",5, wd=="weekend",6) | sort sort_field | fields - sort_field
Return the most recent event:
... | sort 1 -_time
