Hello guys, I'm newbie to ELK and i was trying to connect Logstash to Kibana/Elastic with my own configuration. Logstash seems to be running, but Kibana can't see any data, when i try to create index pattern. Here is my logstash.conf file
> ```
> input {
> file {
> path => "/var/log/messages"
> tags => "smidz"
> }
> }
> filter {
> if "smidz" in [tags] {
> grok {
> match => { "message" => "%{SYSLOGTIMESTAMP:time} %{SYSLOGHOST:host} %{DATA:program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:message}" }
> overwrite => ["message"]
> add_field => {"index_nr" => "111111,222222"}
> }
> if "_grokparsefailure" in [tags] {
> drop{}
> }
> }
> }
>
> output {
> if "smidz" in [tags] {
> elasticsearch{
> hosts => "localhost"
> index => "example_%{tags}"
> }
> }
> stdout{}
> }
>

I'm using "sudo /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash.conf" command to start Logstash, it seems to be working, however the kibana display that i don't have any data.

You do not seem to have anything adding smidz as a tag so the output filter would be ignored.

Accidently edited code, here it is with previous form:
input {
file {
path =\> "/var/log/messages"
tags =\> "smidz"
