Hello,

I want to ship logs from different log source. I need to add a tag to each different log sources.  
This conf doesn' t work !

input {  
beats {  
port =\> 5044  
}  
}

filter {  
if [source]=="xxx.log" {  
mutate {  
add\_tag =\> ["Gvrs"]  
}  
}  
if [source]=="xxx.log" {  
mutate {  
add\_tag =\> "Demo"  
}  
}  
}

output {  
gelf {  
host =\> "xxx.xxx.xxx.xxx"  
port =\> 5044  
protocol =\> "udp"  
}  
}

When you say it doesn't work, is the add\_tag just not adding the tag, or is it generating an error? Either way, have you tried making the tags lower-case (that is, "gvrs" and "demo")?
