Logstash starts but it does not load the data to elasticsearch - elasticsearch

Question

I am trying to read the information in json format from log file and load it in elasticsearch. I am using logstash.
OS: windows 10
ElastiSearch version is 7.6.2
LogStash version is 7.6.2
The log file content is like below:
{"#timestamp":"2020-05-03T15:09:38.255+02:00","#version":1,"message":"The following profiles are active: default","logger_name":"payroll.employee.EmployeeApplication","thread_name":"main","level":"INFO","level_value":20000,"springAppName":"employee"}
{"#timestamp":"2020-05-03T15:09:59.136+02:00","#version":1,"message":"Started EmployeeApplication in 24.892 seconds (JVM running for 27.193)","logger_name":"payroll.employee.EmployeeApplication","thread_name":"main","level":"INFO","level_value":20000,"springAppName":"employee"}
Below it is the logstash.conf file
input {
file {
path => "C:/Users/User/Desktop/Git-Repos/Microservice/elk-logs/employee.log"
start_position => "beginning"
sincedb_path => "NUL"
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "logback-%{+YYYY.MM.dd}"
#user => "elastic"
#password => "changeme"
}
}
I run the logstash like below :
logstash.bat -f C:\Users\User\Desktop\Apps\logstash-7.6.2\config\logstash.conf
And the output is like below:
[2020-05-03T17:52:08,394][INFO ][logstash.outputs.elasticsearch][main] New Elasticsearch output {:class=>"LogStash::Outputs::ElasticSearch", :hosts=>["http://localhost:9200"]}

It seeems that the logstash starts correctly but it fails to insert the data in elasticsearch.
I really would appriciate any help.

P.S
I added output { stdout { codec => json } } and below it is result:

Now i am more confused. The problem is with logstash or elasticsearch or kibana that I am not able to see any information in kibana?

Answer 1

As discussed in the chat. The problem was the pattern of the index name.
Changing the pattern to logback-* worked perfectly.
