Unclear berserker metrics #54

Open DevDema opened 6 years ago

I don't really understand the time unit I get when monitoring kafka performances by BerserkerMetrics. Furthermore, if I specify a load test with a rate generator of 300, i can clearly see that my computer cannot spawn more than 41 requests. What am I doing wrong?

@TheSpartan94 Number of messages being spawned depends on multiple factors. How complex messages are? Currently all messages are generated through one thread using Ranger, if message creation yields lot of different transformations, random number generations, it can be quite expensive to generate single message. How many threads for sending messages are you using? Currently, time unit used within metrics is nano second, there is a plan on making this reporting a bit more user friendly, I hope it will happen in next few months.
