I configured Logstash slowlog like this:

slowlog.threshold.warn: 500ms  
[slowlog.threshold.info](http://slowlog.threshold.info): 400ms  
slowlog.threshold.debug: 300ms  
slowlog.threshold.trace: 100ms

But I see in slowlog file trace entry with "took\_in\_millis":103180  
I don't believe that my event processing 103 seconds, so I looked at source code and found that took\_in\_millis calculated incorrectly, it should be took\_in\_nanos / 1000000 instead of took\_in\_nanos / 1000

Can you raise that as an issue on Github?
