> Key: AMBARI-19847
> URL: https://issues.apache.org/jira/browse/AMBARI-19847
> Project: Ambari
> Issue Type: Bug
> Components: ambari-logsearch
> Affects Versions: 2.5.0
> Reporter: Miklos Gergely
> Assignee: Miklos Gergely
> Fix For: 2.5.0
>
>
> Simulated Log Feeder input writes almost identical log messages, which is not
> really simulates real logs.
> Instead of the logfeeder.simulate.log_message_size property there will be 3
> new properties (the simulated Log Feeders would enforce a minimum, and a
> maximum value, and also set a default for them, if they are not specified):
> logfeeder.simulate.number_of_words - the number of different words that may
> appear in the simulated logs (50 / 1000000, default 1000)
> logfeeder.simulate.min_log_words - the minimum number of words in a simulated
> log message (1 / 10, default 5)
> logfeeder.simulate.max_log_words - the maximum number of words in a log
> message (10 / 20, default 10)
> After the parameters are set each logfeeder will start to load messages like
> this. In each message all the words are different:
> Word000912 Word000903 Word000940 Word000760 Word000564 Word000762 Word000955
> Word000553
> Word000320 Word000218 Word000872 Word000204 Word000120 Word000298 Word000727
> Word000720 Word000475
> Word000413 Word000642 Word000872 Word000464 Word000746 Word000250
> The rest of the properties remain the same:
> 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.sleep_milliseconds - the time interval at which each
> simulated inputs writes one log message at random
