Simulating real time feed

[withersdb]

I'm trying to simulate a live feed of event data to Kafka. I tried running with the following config, following the example of this Confluent demo:

bin/eventsim -c "examples/example-config.json" /
-start-time "`date +"%Y-%m-%dT%H:%M:%S"`" /
--end-time "2016-05-18T17:00:00" --nusers 2000 /
--kafkaBrokerList broker1:9092 --kafkaTopic eventsim /
--continuous

Which provides the output "starting to generate events," but no messages are being published. Publishing simulated historical data (i.e. with a past start and end time) to Kafka all at once works fine. Could you add an example to the documentation about how to start a real time simulated event stream?

@withersdb Any luck with this?

I needed something similar. When the continuous flag is set, the thread will sleep the difference between current sys time and the last generated event's time stamp. With a start date and end date that differ by a few minutes, the first event's time stamp was oddly set to 15 days ago. The thread would be sleeping for ~360 hours. That would explain your issue. I'm looking into a fix.
