Hi experts,

Im new to elk and need your help here.  
I m trying to pass a value from filebeat to logstash but been unsuccessful.

This is what I have mentioned in filebeat.yml  
########filebeat.yml#########  
output.logstash:

# The Logstash hosts

hosts: ["localhost:5044"]  
fields:  
env: uat  
################

#########logstash.conf#########  
output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "aia-mpv-%{env}-%{+YYYY.MM.dd}"}  
}  
########################

But in kibana I still see indices as  
aia-mpv-%{env}-2020.03.03  
Value is not getting replaced, please help.
