Logstash _grokparsefailure


#1

Hi,
this is my first post and I am new user of ELK. I have succesfully configured ELK on CentOS and working fine and now I am sending data so that i can create dashboards. However I am stuck at one point and though i have read many post and the online logstash documentation, i dont seem to get past.

So basically i have a log file and I am shipping that logfile to logstash which is working fine via filebeat for windows.
Now I have the following logstash configuration, which will extract fields from the unstructured data which looks like this

{user@domain.com} Active 11.11.11.11 12.12.12.12 Eap Tls 47975 9/12/2018 5:10:15 AM 8046963 10435405 Ikev2 216

I have created a conf file named filebeat1.conf and placed in /etc/logstash/conf.d and it looks like following:

input {
beats {
port => 5044
type => "log"
}
}

filter {
if [type] == "log" {
grok {
match => { "message" => "{%{GREEDYDATA:username}} %{SPACE} %{DATA:status} %{SPACE} %{IPV4:clientip} %{SPACE} %{IPV4:ispip} %{SPACE} %{DATA:protocol} %{SPACE}
%{INT:duration} %{SPACE} %{DATESTAMP:connectiontime} %{DATA} %{SPACE} %{INT:bytesin} %{SPACE} %{INT:bytesout} %{SPACE} %{HOSTNAME:security} %{SPACE} %{INT:ba
ndwidth} %{SPACE}" }
}
}

   }

output {
elasticsearch {
hosts => ["http://localhost:9200"]
}
}

However in Kibana i a getting _grokparsefailure. I have tested the pattern in https://grokdebug.herokuapp.com/ and it looks fine there but when i copy and paste the pattern in conf file then i get grok parse error and the logstash log file shows
