Can someone please help on this same .


(Christian Dahlqvist) #2

Which JVM are you using?


(Shashank Jain) #3

Hi ,

I am using JAVA 1.8 .

[root@vielk01dsy bin]# java -version
openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-b16)
OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)


(Christian Dahlqvist) #4

Is this the host Logstash is running on? Can you try leaving this out so it uses the default (0.0.0.0)?


(Shashank Jain) #5

no it is filebeat host .

logstatch is on different host .


(Christian Dahlqvist) #6

Then remove it as it specified which host Logstash should bind to.


(Shashank Jain) #7

Sorry didnt get ,

if i remove this host then how logstach would receive log from filebeat ?

please correct if i am wrong .


(Christian Dahlqvist) #8

You should not specify host parameter for the beats input. Using the default will make Logstash bind to all network interfaces on the host it is running, which will allow Filebeat to connect to it.


(Shashank Jain) #9

By removing host parameter ,

i am facing errors with different way ,

after starting loghstach

./logstash -f ../modules/test.conf

[root@vielk01dsy bin]# ./logstash -f ../modules/test.conf

it is not going beyond this .

Also on Filebeat_host i am getting below errors ,

sudo ./filebeat -e -c filebeat.yml -d "publish"

please suggest now .

Filebeat config file :-

filebeat.prospectors:

Each - is a prospector. Most options can be set at the prospector level, so

you can use different prospectors for various configurations.

Below are the prospector specific configurations.

  • input_type: log

    Paths that should be crawled and fetched. Glob based paths.

    paths:

    • /var/log/*.log
      #- c:\programdata\elasticsearch\logs*

#----------------------------- Logstash output --------------------------------
output.logstash:

The Logstash hosts

hosts: ["logstach_host:5044"]

Logstach config file :-

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

The filter part of this file is commented out to indicate that it is

optional.

filter {

}

output {
stdout { codec => rubydebug }
}


(Christian Dahlqvist) #10

Please format your config file entries as preformatted text when pasting them as it is very hard to read them as they are currently formatted.

Do you have connectivity between the nodes? Can you e.g. telnet to port 5044 on the Logstash host from the node where Filebeat is running?


(Shashank Jain) #11

Filebeat config file :-

filebeat.prospectors:
input_type: log
paths:
/var/log/.log
#- c:\programdata\elasticsearch\logs

#----------------------------- Logstash output --------------------------------
output.logstash:
The Logstash hosts

hosts: ["logstach_host:5044"]

Logstach config file :-

input {
beats {
port => "5044"
}
}
filter {
}

output {
stdout { codec => rubydebug }
}


(Shashank Jain) #12

I have shared config files above .

also i cant telenet to logstach server

telnet logstach_host 5044
Trying logstach_host...
telnet: connect to address logstach_host : No route to host

how to resolve it .

do i need to update iptables ?


(Christian Dahlqvist) #13

If you can not telnet and the hostname is correct, you may need to check iptables etc.


(Shashank Jain) #14

Need your help on Implementing ELK stack with architecture .

DO you have any docs for the same
