Events-processing

• Projects

Overview

Processing logic that can be applied to event streams. The logic corresponding to each of the procedures listed below can be invoked from command line using the corresponding "command".

Procedures

describe

Displays the structure (properties) of the events flowing through the event stream pipeline. The property names shown in the results of this command can then be used to assemble the output format string of the "output" command, specified with the -o|--output-format command option.

time-gaps

Identifies time gaps in the log.

count

Displays the number of events that match the query.

Some utilities rely on the fact that they can invoke this procedure with the abbreviated command-line form "-c".

exclude

Filter out the events that match the query, and only display those that do not match.

Some utilities rely on the fact that they can invoke this procedure with the abbreviated command-line form "-x".

This procedure is equivalent with the grep --invert-match (-v) option.
