I am seeing below logs being displayed continuously in debug mode. What may be the issue?

```

There is no issue. This is a debug-level log message indicating that the elasticsearch output plugin is about to attempt to flush whatever is in its buffer.

The above message is rolling 4-5 times per second.. is it fine?

Due to this I am not seeing anything in kibana

What does your elasticsearch output configuration look like?

> Due to this I am not seeing anything in kibana

What makes you draw the conclusion that they're related? Does Kibana work fine if you shut down Logstash?

I was wrong. This was not the issue; created another index and worked
