@sudhagar_ramesh This is my filebeat.yml setup

###################### Filebeat Configuration Example #########################

# This file is an example configuration file highlighting only the most common
# options. The filebeat.reference.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html

# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.

# ============================== Filebeat inputs ===============================

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.

# filestream is an input for collecting log messages from files.
- type: log

  # Unique ID among all inputs, an ID is required.
  #id: my-filestream-id

  # Change to true to enable this input configuration.

  # 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']

  # are matching any regular expression from the list. By default, no files are dropped.
  #prospector.scanner.exclude_files: ['.gz$']

  # Optional additional fields. These fields can be freely picked
  # to add additional information to the crawled log files for filtering
  #fields:

# options here or by using the `setup` command.
#setup.dashboards.enabled: false

# The URL from where to download the dashboards archive. By default this URL
# has a value which is computed based on the Beat name and version. For released

# =================================== Kibana ===================================

# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.

#logging.selectors: ["*"]

# ============================= X-Pack Monitoring ==============================
# Filebeat can export internal metrics to a central Elasticsearch monitoring
# cluster.  This requires xpack monitoring to be enabled in Elasticsearch.  The
# reporting is disabled by default.

# Set to true to enable the monitoring reporter.
#monitoring.enabled: false

# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch

#monitoring.cluster_uuid:

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch

# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.
#monitoring.elasticsearch:

# ============================== Instrumentation ===============================

# Instrumentation support for the filebeat.

Hello @Rajesh119

Are you are accessing Elasticsearch cluster with authentication then please mention its credentials here.

example:

output.elasticsearch:
  hosts: ["https://myEShost:9200"]
  username: "<elastic-cluster-username>"
  password: "<elastic-cluster-pwd>"

Keep Posted !!! Thanks !!!

@sudhagar_ramesh i don't have any credentials

Thanks&Regards

Ensure that there files present in the path that has been mentioned in filebeat.yml configuration

/var/log/*.log

Run setup command once the above configuration verified

output.elasticsearch:
  hosts: ["https://myEShost:9200"]
  username: "<elastic-cluster-username>"
  password: "<elastic-cluster-pwd>" 
  index: "<your-index-name>"
11

yes i have a log files in this location

/var/log/*.log

After i run command

sudo filebeat setup

Output:
Index setup finished.
Loading dashboards (Kibana must be running and reachable)
Loaded dashboards
Loaded Ingest pipelines

could you please execute and share the output

sudo filebeat setup -e

This is the output for below command:

sudo filebeat setup -e

Check in Elasticsearch whether the index has been created.
Create index pattern to view the same in kibana

15

@sudhagar_ramesh Please let me know how to check index in Elasticsearch

16

curl http://localhost:9200/_cat/indices?v

17

if the below configuration has been done then the index name whichever you in this filebeat configuration, the same index name would be seen in the output of above command.

output.elasticsearch:
  hosts: ["https://myEShost:9200"]
  username: "<elastic-cluster-username>"
  password: "<elastic-cluster-pwd>" 
  index: "<your-index-name>"

Post which you will be able to see the index in Elasticsearch
