Events User Manual - Parse Command

Internal

• events User Manual

Overview

The command configures an events pipeline to process text data arriving at stdout and convert it into a time series at stdout, according to the specified format.

Syntax

events < input-file <input-format-specification>

Input Format Specification

The format of the input stream can be specified either verbatim, in-line in the command line or in a file whose name is specified on the command line, or by a name.

In-Line Input Formats

To specify a verbatim format in line, use:

-i format-specification

or

--input-format=format-specification

If the format specification is stored in a file on an accessible filesystem, it can be specified as follows:

--input-format-file=<file-name-that-contains-input-format>

Formats that can be specified in-line usually apply to line-based logs, such as Apache httpd logs, or CSV files. A httpd log format can be specified in-line, introduced by the -i short option -i (or with the long form equivalent --input-format="...") as follows:

-i "%h %u [%t] \"%r\" \"%q\" %{c,JSESSIONID} %{i,Some-Request-Header} %s %b %D"

More details about the httpd log format support can be found in the "Apache httpd log format" section. A CSV file format can be specified in-line as follows:

-i "timestamp, count, status-code"

More details about the CSV format support can be found in the "CSV format" section.

When an in-line format is used, the runtime will apply heuristics and try to figure out what type of format was specified.

Named Formats

A format specified by its logical name can be provided as follows:

-i format-name

or

--input-format=format-name

Supported Formats

Apache httpd log format
