dummy

The in_dummy
input plugin generates dummy events. It is useful for testing, debugging, benchmarking and getting started with Fluentd.
Example Configuration
in_dummy
is included in Fluentd's core. No additional installation process is required.
<source>
@type dummy
dummy {"hello":"world"}
</source>
Please see the Config File article for the basic structure and syntax of the configuration file.
Parameters
type (required)
The value must be dummy
.
tag (required)
The value is the tag assigned to the generated events.
dummy (optional)
The dummy data to be generated. It should be either an array of JSON hashes or a single JSON hash. If it is an array of JSON hashes, the hashes in the array are cycled through in order. By default, the value is [{"message":"dummy"}]
(i.e., it continues to generate events with the record {"message":"dummy"}).
auto_increment_key (optional, string type)
If specified, each generated event has an auto-incremented key field. For example, with auto_increment_key foo_key
, the first couple of events look like
2014-12-14 23:23:38 +0000 test: {"message":"dummy","foo_key":0}
2014-12-14 23:23:38 +0000 test: {"message":"dummy","foo_key":1}
2014-12-14 23:23:38 +0000 test: {"message":"dummy","foo_key":2}
rate (optional, integer type)
It configures how many events to generate per second. The default value is 1.
log_level option
The log_level
option allows the user to set different levels of logging for each plugin. The supported log levels are: fatal
, error
, warn
, info
, debug
, and trace
.
Please see the logging article for further details.
