FileBeat Sending Logs in binary format

Elastic Stack Beats
1

Hi All,

I am trying to set-up a centralized log management in my infra, for this I am using Graylog. I am pushing my component logs from clients to the Graylog Server using Filebeat ( Version - 5.1.1 ). I am not sure why the logs sent by FileBeat are in binary format , as i am new with FileBeat I am not sure if I miss out anything related to the configuration.

FileBeat Configuration:

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

# This file is an example configuration file highlighting only the most common
# options. The filebeat.full.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

#=========================== Filebeat prospectors =============================

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:
    - /path-to-log-file/web.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 field can be freely picked
  # to add additional information to the crawled log files for filtering
  #fields:
  #  level: debug
  #  review: 1

  ### Multiline options

  # Mutiline 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

#================================ General =====================================

# The name of the shipper that publishes the network data. It can be used to group
# all the transactions sent by a single shipper in the web interface.
#name:

# The tags of the shipper are included in their own field with each
# transaction published.
#tags: ["service-X", "web-tier"]

# Optional fields that you can specify to add additional information to the
# output.
fields:
  env: Staging-1

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

# Configure what outputs to use when sending the data collected by the beat.
# Multiple outputs may be used.

#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:
  # Array of hosts to connect to.
#  hosts: ["graylog-server-ip:9200"]

  # Optional protocol and basic auth credentials.
  #protocol: "https"
  #username: "elastic"
  #password: "changeme"

#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
  hosts: ["graylog-server-ip:5555"]

  # 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"

#================================ Logging =====================================

# Sets log level. The default log level is info.
# Available log levels are: critical, error, warning, info, debug
logging.level: debug

# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publish", "service".
logging.selectors: ["*"]

That sounds like a problem with the input configuration to Graylog where it doesn't understand the format of the data from the Logstash output in Beats. I haven't used Graylog so I can't offer any help on that side.

Firstly apologies for the delay in my response and thank you much for your reply andrewkroh. It was input issue as you told, fixed it now.

4

Can you please tell us how you fixed it for the benefit of others that have a similar problem.

In the updated version of Graylog, we have a option called filebeat in the Types of input. Initially i was trying with plain TCP Text option, which was the issue.
