Description

Enable simulating input files in a configurable way. The parameters has to be set at custom logfeeder.properties

Available parameters:
logfeeder.simulate.input_number - number of paralell inputs (threads) loading the logs, if it is set and not 0 then all the rest of the configured inputs are ignored (running in simulation mode)!!

logfeeder.simulate.log_ids - comma separated list of the log ids to propagate at random, if not set by default all the available logs are propagated at random, example: storm_drpc,storm_logviewer,storm_nimbus

logfeeder.simulate.log_level - the level of the simulated log messages, by default WARN

logfeeder.simulate.log_message_size - the length of the simulated log messages, can't be less then 50 due to log message prefix, the rest is filled with 'X' characters

logfeeder.simulate.sleep_milliseconds - the time interval at which each simulated inputs writes one log message at random

The text of the log message is like this:
Simulated log message for testing, line 00000001 XXXXXXXXXXXXXXXXXXXXXXXXXX
