I wrote a .conf file as in the example given in the Logstash documentation and tried to run it. Logstash started but when I gave the input it gave the error as mentioned in the title.
I am using Windows 8.1 and the .conf file in saved in the logstash-1.5.0/bin.
Here is the .conf file:
input { stdin { } }
output {
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
Here is the screenshot of the command prompt:
Try with this, "logstash" should be the same name of your cluster in Elasticsearch.yml
output {
elasticsearch {
cluster => "logstash"
}
}
I found the error. It was because I have not installed elasticsearch before running logstash.
Thanks for trying to helping me out

I am very very new to ELK, I installed ELK version 5.6.12 on CentOS sever. Elasticsearch and Kibana works fine. But I cannot connect Logstash to Elastic search.
I have set environment variable as
export JAVA_HOME=/usr/local/jdk1.8.0_131
export PATH=/usr/local/jdk1.8.0_131/bin:$PATH
I run simple test :
bin/logstash -e 'input { stdin { } } output { elasticsearch { host => localhost:9200 protocol => "http" port => "9200" } }'
I get error :
WARNING: Could not find logstash.yml which is typically located in
$LS_HOME/config or /etc/logstash. You can specify the path using --
path.settings. Continuing using the defaults
Could not find log4j2 configuration at path
/etc/logstash/logstash.yml/log4j2.properties. Using default config which
logs errors to the console
Simple "slash" mentioned in official documentation of Logstash works like following :
$bin/logstash -e 'input { stdin { } } output { stdout {} }'
Hello

The stdin plugin is now waiting for input: {
"#version" => "1",
"host" => "localhost",
"#timestamp" => 2018-11-01T04:44:58.648Z,
"message" => "Hello" }
What could be the problem?
I have installed ELK stack on windows and configured Logstash to read an Apache Log file. I cant seem to see the output in Elasticsearch. I am very new to ELK stack.
Environment Setup
Elasticsearch: http://localhost:9200/
Logstash :
Kibana : http://localhost:5601/
All 3 applications above are running as a service.
I have created a file called "logstash.conf" to read apache logs in "C:\Elk\logstash\conf\logstash.conf" with the following :
input {
file {
path => "C:\Elk\apache.log"
start_position => "beginning"
}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
}
I then restarted my Logstash service and now wish to see if elasticsearch is indexing the content of my log. How do i go about doing this ?
try adding following lines to your logstash conf and let us know if there are any grokparsing failures...which would mean your pattern used in filter section is not correct..
output {
stdout { codec => json }
file { path => "C:/POC/output3.txt" }
}
i have 3 node setup
10.x.x.1 - application and filebeat
10.x.x.2 - machine for parsing and logstash
10.x.x.3 - having centralized logstash node from where we need to push messages into Elastic Search
in 10.x.x.2 when i set the output codec to stdout , i can see the messages coming from 10.x.x.1.
Now, i need to forward all the json messages from 10.x.x.2 to 10.x.x.3 . I tried using TCP. But the messages are not gettting sent.
10.x.x.2 logstash conf file
input {
beats {
port => 5045
}
}
output{
#stdout { codec => rubydebug }
tcp{
host => "10.x.x.3"
port => 3389
}
10.x.x.3 logstash conf file
input{
tcp{
host => "10.x.x.3"
port => 3389
#mode => "server"
#codec => "json"
}
}
output{
stdout{ codec => rubydebug }
}
is there any plugin which can send json data from one logstash to another logstash server
Your config should work.
But you have to be carreful with the "codec" properties.
Try first to set it to "line" on the output AND the input plugins of the two logstash.
And see if log are incoming.
With the codec set to "line" you will have logicly no problem to forward the logs.
Then work on the "json" properties.
Do not forget that you can activate the debug mode of logstash with the argument --debug and you can log with the arguments : -l logFileName
When you start to work with the codec json look for "_jsonparsefailure" tags, which could explain why it do not transfert logs between the two logstash.
The code mentioned is my logstash conf file . I provide my nginx access log file as input and output to elasticsearch .I also write the output to a text file which works fine .. But the output is never been written to elasticsearch.
input {
file {
path => "filepath"
start_position => "beginning"
}
}
output {
file {
path => "filepath"
}
elasticsearch {
host => localhost
port => "9200"
}
}
I also tried executing logstash binary from command line using -e option
input { stdin{ } output { elasticsearch { host => localhost } }
which works fine. I get the output written to elasticsearch.. But in the former case i dont . Help me solve this
I tried a few things, I have no idea why your case with just host works. If I try it, i get timeouts. This is the configuration that works for me:
elasticsearch {
protocol => "http"
host => "localhost"
port => "9200"
}
I tried with logstash 1.4.2 and elasticsearch 1.4.4
I'm Unable to load index to elasticsearch using logstash. The follwing are my logstash.conf settings. To me config settings seems fine. Please help if I'm missing something.
Assume that Logstash & elastic search services are running fine.
input {
file {
type => "IISLog"
path => "C:/inetpub/logs/LogFiles/W3SVC1/u_ex140930.log"
start_postition => "beginning"
}
}
output {
stdout { debug => true debug_format => "ruby"}
elasticsearch_http {
host => "localhost"
port => 9200
protocol => "http"
index => "iislogs2"
}
}
You can start with checking the following:
Check the logstash log file for errors.
Run the following command:telnet localhost 9200 and verify you are able to connect.
Check elasticsearch log files for errors.
