Hi

I have an ELK platform version 7.1.0, to fix a timestamp inconsistency between my servers and Kibana I created a logstash filter, this filter read the timestamp from the logs and applied it in the filed @timestamp in Kibana, so far so good, now I´m trying to use some dashboards for PostgreSQL but when I tried to read the information from the logs all the PostgreSQL module fields that filebeat sent are deleted by logstash (user name, query, log duration, etc) so I was wondering if any of you know how to pass this fields trough logstash and avoid this data loss, this is the filter that I have to fix the timestamp issue.

input {  
beats {  
port =\> 5044  
}  
}  
filter {  
grok {  
match =\> ["message", "%{TIMESTAMP\_ISO8601:timestamp}"]  
}  
date {  
match =\> ["timestamp", "ISO8601"]  
}  
}  
output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"  
}  
}

Log example from filebeat to elasticsearch
