How to solve this error?

Exiting: Couldn't connect to any of the configured Elasticsearch hosts. Errors: [Error connection to Elasticsearch http://localhost:9600: Failed to parse JSON response: json: cannot unmarshal string into Go struct field .Version of type struct { Number string }]

Logstash logs

Hello People , please help to to solve this problem. i have error in Start filebeat in logstash logs.

Step to install and configure filebeat with logstash

Christian_Dahlqvist · January 8, 2019, 9:05am

Do you have the Elasticsearch HTTP port mapped to 9600 instead of the default 9200?

Bhavesh_Padharia · January 8, 2019, 10:02am

I get error when i install file-beat and use this command ..

Start Filebeat

The setup command loads the Kibana dashboards. If the dashboards are already set up, omit this command.

./filebeat setup
./filebeat -e
> ```

Christian_Dahlqvist · January 8, 2019, 10:03am

I do not see how that answers my question.

What does your Elasticsearch and Filebeat configuration look like?

Bhavesh_Padharia · January 8, 2019, 10:11am

Filebeat.yml file

Filebeat input

filebeat.inputs:

Each - is an input. Most options can be set at the input level, so

you can use different inputs for various configurations.

Below are the input specific configurations.

type: log

Change to true to enable this input configuration.

enabled: true

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

paths:
- /home/system/Documents/*.log
  #- c:\programdata\elasticsearch\logs*
Exclude lines. A list of regular expressions to match. It drops the lines that are

matching any regular expression from the list.

#exclude_lines: ['^DBG']

Include lines. A list of regular expressions to match. It exports the lines that are

matching any regular expression from the list.

#include_lines: ['^ERR', '^WARN']

Exclude files. A list of regular expressions to match. Filebeat drops the files that

are matching any regular expression from the list. By default, no files are dropped.

#exclude_files: ['.gz$']

Optional additional fields. These fields can be freely picked

to add additional information to the crawled log files for filtering

#fields:

level: debug

review: 1

Multiline options

Multiline can be used for log messages spanning multiple lines. This is common

for Java Stack Traces or C-Line Continuation

The regexp Pattern that has to be matched. The example pattern matches all lines starting with [

#multiline.pattern: ^[

Defines if the pattern set under pattern should be negated or not. Default is false.

#multiline.negate: false

Match can be set to "after" or "before". It is used to define if lines should be append to a pattern

that was (not) matched before or after or as long as a pattern is not matched based on negate.

Note: After is the equivalent to previous and before is the equivalent to to next in Logstash

#multiline.match: after

#============================= Filebeat modules ===============================

filebeat.config.modules:

Glob pattern for configuration loading

path: ${path.config}/modules.d/*.yml

Set to true to enable config reloading

reload.enabled: true

Period on which files under path should be checked for changes

#reload.period: 10s

#==================== Elasticsearch template setting ==========================

setup.template.settings:
index.number_of_shards: 3
#index.codec: best_compression
#_source.enabled: false

Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.

This requires a Kibana endpoint configuration.

setup.kibana:

Kibana Host

Scheme and port can be left out and will be set to the default (http and 5601)

In case you specify and additional path, the scheme is required: http://localhost:5601/path

IPv6 addresses should always be defined as: https://[2001:db8::1]:5601

#host: "localhost:5601"

Kibana Space ID

ID of the Kibana Space into which the dashboards should be loaded. By default,

the Default Space will be used.

#space.id:

#================================ Outputs =====================================

Configure what output to use when sending the data collected by the beat.

#-------------------------- Elasticsearch output ------------------------------
output.elasticsearch:
hosts: ["localhost:9200"]
username: "system"
password: "<123>"
setup.kibana:
host: "localhost:5601"

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

The Logstash hosts

hosts: ["localhost:5044"]

Optional SSL. By default is off.

List of root certificates for HTTPS server verifications

#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]

Certificate for SSL client authentication

#ssl.certificate: "/etc/pki/client/cert.pem"

Client Certificate Key

#ssl.key: "/etc/pki/client/cert.key"

Christian_Dahlqvist · January 8, 2019, 10:26am

Can you please format the configs using the </> tool available in the UI? It is very hard to read as it is now...

How are you running the components? VirtualBox? Which operating system are you using?

xeraa · January 8, 2019, 2:41pm

open /var/log/filebeat/filebeat: permission denied: You need to run this with sudo on Ubuntu — otherwise the file permissions are wrong as you can see in this error message.

Bhavesh_Padharia · January 9, 2019, 7:55am

in vm - ubantu 16.04LTS

Bhavesh_Padharia · January 9, 2019, 7:56am

will you share me that command.

xeraa · January 11, 2019, 12:50am

To fix the file permission errors you need to run sudo filebeat setup instead of just filebeat setup.
Is Kibana running on localhost? fail to execute the HTTP GET request: Get http://[localhost:5601]:5601/api/status: lookup localhost:5601: no such host. is probably the next thing you will need to fix.

Bhavesh_Padharia · January 11, 2019, 12:24pm

Thanks for given time my error solve now.
