streamstats command syntax details

Syntax

The required syntax is in bold.

streamstats <aggregation> ...
[<by-clause>]...
[<reset-clause>]

The AS and BY keywords are displayed in uppercase in the syntax and examples to make the syntax easier to read. You can specify these keywords in uppercase or lowercase.

Required arguments

aggregation
Syntax: <aggregate-function> "("<field> [AS <field>] ) ["," <aggregate-function> "("<field> [AS <field>] ) ]...
Description: A statistical aggregation function. The function can be applied to an eval expression, or to a field or set of fields. You can specify multiple aggregation functions. Separate each aggregation function with a comma.
By default, the name of the field added to the output is the same as your function. For example, if your search is ... | streamstats avg(bytes) the field name in the output is avg(bytes). Use the AS clause to place the generated result into a new field with a name that you specify, for example ... | streamstats avg(bytes) AS 'avg of bytes'.
The syntax for the <aggregate-function> depends on the function that you use. See Stats and charting functions Quick Reference for information about the statistical functions.

Optional arguments

by-clause
Syntax: BY <field-list>
Description: The name of one or more fields to group the results by. The <by-clause> returns one row for each distinct value in the <by-clause> fields. Think of the <by-clause> as a grouping. You cannot use the wildcard character to specify multiple fields with similar names. You must specify each field separately.
Default: If no <by-clause> is specified, the streamstats command returns a running aggregation for each row in the incoming result set.
reset-clause
Syntax: reset [before <eval-expression>] [after <eval-expression>] [onchange]
Description: You can specify one or more reset condition. If multiple conditions are specified, the reset occurs when any of the conditions triggers a reset. See Usage.
Default: No reset is applied to the results.
