Hi,

I am trying to use gelf input plugin for some ESB logs with log4j2-GELF appender (just started ELK Stack for logging). I am successful in getting the logs through a configured port. As there are around 100 apps (will keep adding) and some are WebServices which keeps spitting logs, is it ok to have all logs pumped through a single port; as would that create any performance problem or missing some logs? Like LS - File beat has that backpressure-sensitive protocol, is there something like this in gelf Input plugin?

input {  
gelf{  
host =\> "testelkstacksrvr1"  
port =\> 9090  
}

}

Thanks,  
Raj
