If no output format is specified, the output procedure will inspect the event, and will try to use, in order, the preferred representation, as returned by the event (if any), the raw representation, as returned by event (if any) and then a simple representation consisting in the event's timestamp, if available, and then the event's toString() invocation result.

Overview

The default procedure to handle event streams: the procedure inspects the events and sends their string representation to the configured output stream.

The procedure can be configured with an output format.

One way to provide the format specification is on command-line: format specification arguments follow the "-o" marker and end either with the last argument or when a higher level argument (file, for example) is encountered.

some-parser [output] -o <output-format> ./file.txt
cat ./file.txt | some-parser [output] -o <output-format>

If no output format is specified, the output procedure will inspect the event, and will try to use, in order: the preferred representation, as returned by the event (if any), the raw representation, as returned by event (if any) and then a simple representation consisting in the event's timestamp, if available, and then the event's toString() invocation result.

Output Format

The output format can be used to:

Displaying Specific Event Properties

Displaying Specific Event Types
