Filebeat Configuration

To check this example put above sample logs in file app.log and configure filebeat.yaml file as below:

Prospectors Configuration


filebeat.prospectors:
- type: log
- D:your-directory-path*.log*

#Multiline configutaion as per above logs to stack trace
multiline.pattern: '^[([0-9]{4})-([0-9]{2})-([0-9]{2})'
multiline.negate: true
multiline.match: after

#Elasticsearch Ingest Node Pipe Line configuration
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["localhost:9200"]
  pipeline: grok-pipeline

Below is complete sample filebeat.yaml file

######Filebeat Configuration Example ########
#=========================== Filebeat prospectors =============================
filebeat.prospectors:

# Below are the prospector specific configurations.
- type: log
  # Change to true to enable this prospector configuration.
  enabled: true
  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    - D:fsv_logs*.log*
    #- c:programdataelasticsearchlogs*

  # 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

  # 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 all lines starting with [
  multiline.pattern: '^[([0-9]{4})-([0-9]{2})-([0-9]{2})'

  # Defines if the pattern set under pattern should be negated or not. Default is false.
  multiline.negate: true

  # 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: false

  # 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

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

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

#-------------------------- Elasticsearch output ------------------------------
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["localhost:9200"]
  pipeline: grok-pipeline
  # Optional protocol and basic auth credentials.
  #protocol: "https"
  #username: "elastic"
  #password: "changeme"

In above filbeat.yaml you can check for configuration for filbeat, multiline processing logs and Ingest Node pipe line.

Ingest Node pipeline Creation and configure Processors

You can execute below commands by using curl or Kibana Adsense /Dev tools to create pipeline to execute processors.

Here I have configured below processors with in pipeline:

grok processor : grok processor will parse logs message to fields values which will help to do analysis.

date processor : date processor will change @timestamp values corresponding timestamp of each logs line. Which will help while indexing and sorting of logs based on timestamp.

date_index_name : date_index_name processor will create elasticsearch indexes with suffix as date so that easily maintain indexes as per durability.

Kibana adsense

Elasticsearch Ingest Node Vs Logstash Vs Filebeat


Elasticsearch Ingest Node

Ingest node use to pre-process documents before the actual document indexing
happens. The ingest node intercepts bulk and index requests, it applies transformations, and it then passes the documents back to the index or bulk APIs.

Logstash

Logstash is a server-side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then sends it to different output sources like Elasticsearch, Kafka Queues, Databases etc.

Filebeat

Filebeat is lightweight log shipper which reads logs from thousands of logs files and forward those log lines to centralize system like Kafka topics to further processing on Logstash, directly to Logstash or Elasticsearch search.

There is overlap in functionality between Elasticsearch Ingest Node , Logstash and Filebeat.All have there weakness and strength based on architectures and area of uses. You cam also integrate all of these Filebeat, Logstash and Elasticsearch Ingest node by minor configuration to optimize performance and analyzing of data.

Below are some key points to compare Elasticsearch Ingest Node , Logstash and Filebeat.
