However I optimize with various config params. There are always 3 seconds delay.  
My filebeat.yml as below:

filebeat.inputs:

- type: log  
enabled: true  
fields:  
log\_topics: ngaudio\_test  
paths:

- type: log  
enabled: true  
fields:  
log\_topics: ngappuse\_test  
paths:

filebeat.config.modules:  
path: ${path.config}/modules.d/\*.yml  
reload.enabled: false

queue.mem:  
events: 4096  
flush.min\_events: 512  
flush.timeout: 0s

What is your requirement you mean by real time? Filebeat is not able to collect logs in real time, only in near real time.  
You could decrease `scan_frequency` to `1s`, so Filebeat checks for new changes every second.
