Logstash is not connecting with ElasticSearch and I don't find any error

Elastic Stack Logstash
1

Hell I'm new with elasticSearch and logstahs and I'm having some problems.

I'm Trying to connect Logstash and ES with a simple conf file but nothing happens in ES and I can get the error from the logs.

input {

 	file{
 		path => ["/Users/asanzgarrigues/Desktop/logstash-plain.log"]
 		start_position => "beginning"
 		type => "logs"
 	}
 }
 # The filter part of this file is commented out to indicate that it is
 # optional.
 # filter {
 #
 # }
 output {
 elasticsearch { 
 	 hosts => ["http://localhost:9203"]
 	 action => "index"
 	 index => "prueba"
 	 } 
     stdout { codec => rubydebug }
 }

The ES port is 9203 and I change it in the Elasticsearch.yml configuration file.

When I executed logstahs with:

C:\Users\asanzgarrigues\Desktop\elastic\logstash-5.3.0\bin>logstash -f prueba.conf

I get the following response:

The execution with --debug is too big but it finalizes in a loop like this:

If the complete debug log is necessary i can post it in various posts

I need your help, I'm blocked with it.

Thank you!

@Alvaro_Sanz_Garrigue,
Try these options

  1. check if ES is working at 9203, check http://localhost:9203 in browser and verify
  2. can you try to touch the log file.
    Ex: delete the last line in the log file while Logstash is active
  3. add a sample filter and check
  4. output to a file so you are sure that some data is parsed and ready to be shipped out of logstash

Regards,
Ruthu

Thanks for your tips, but it still not working.

1.check if ES is working at 9203, check http://localhost:92032 in browser and verify
I have checked it and it seems that it is working correctly.

2. can you try to touch the log file.
I did it
3. add a sample filter and check
4. output to a file so you are sure that some data is parsed and ready to be shipped out of logstash
The new .conf file is the following:

> input {
> 	file{
> 		path => ["/Users/asanzgarrigues/Desktop/logstash-plain.log"]
> 		start_position => "beginning"
> 		type => "logs"
> 	}
> }

> filter {
> grok {
>     match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}\]\[%{LOGLEVEL:log_level} \]\[%{DATA:info}\]%{GREEDYDATA:message}"  }
>   }
>  }
> output {

> 	file{
> 		path => ["/Users/asanzgarrigues/Desktop/prueba.json"]
> 		}
>     stdout { codec => rubydebug }
> }

The log format is the following:

[2017-04-26T15:05:18,794][INFO ][logstash.outputs.elasticsearch] Elasticsearch pool URLs updated {:changes=>{:removed=>[], :added=>[http://localhost:9203/]}}

When I execute again logstash now appears the following but nothing is written in the destination file.

C:\Users\asanzgarrigues\Desktop\elastic\logstash-5.3.0\bin>logstash -f prueba.conf
Sending Logstash's logs to C:/Users/asanzgarrigues/Desktop/elastic/logstash-5.3.0/logs which is now configured via log4j2.properties

Now I'm totally lost hahaha. I supose that I'm missing something during the configuration or installation. But I just download ES and logstash zips from elastic.co and cjange the elastic port configuration and execute the commands bin\elasticsearch.bat and bin/logstash -f logstash.conf indicated in https://www.elastic.co/downloads/elasticsearch
and
https://www.elastic.co/downloads/logstash

Sorry if my english is too bad. And Thank you for help @Ruthu_Ramya

I finally make it works. I was doing it in the enterprise laptop which is restricted. I create a Ubuntu VM where I have the whole control, and there with the same configuration it finally works.
So I guess that in my enterprise computer there were permissions issues or something like that which denies logstash to work as expected.

You can close this topic.
Thank you

@zegdene, try as in the sample posted here. Thats the right one.
You can use stdout if you want to see the results on the console, refer: https://www.elastic.co/guide/en/logstash/current/plugins-outputs-stdout.html
