Filebeat日誌採集

Filebeat日誌採集

一、軟件介紹

Filebeat

1，概述

Filebeat是一個日誌文件託運工具，在你的服務器上安裝客戶端後，filebeat會監控日誌目錄或者指定的日誌文件，追蹤讀取這些文件（追蹤文件的變化，不停的讀），並且轉發這些信息到elasticsearch或者logstarsh中存放。

2，工作流程

以下是filebeat的工作流程：當你開啓filebeat程序的時候，它會啓動一個或多個探測器（prospectors）去檢測你指定的日誌目錄或文件，對於探測器找出的每一個日誌文件，filebeat啓動收割進程（harvester），每一個收割進程讀取一個日誌文件的新內容，併發送這些新的日誌數據到處理程序（spooler），處理程序會集合這些事件，最後filebeat會發送集合的數據到你指定的地點。(個人理解，filebeat是一個輕量級的logstash，當你需要收集信息的機器配置或資源並不是特別多時，使用filebeat來收集日誌。日常使用中，filebeat十分穩定，筆者沒遇到過宕機。)

二、安裝部署

1，安裝前準備

To get started with your own Filebeat setup, install and configure these related products:
* Elasticsearch for storage and indexing the data.
* Kibana for the UI.
* Logstash (optional) for inserting data into Elasticsearch.

2，windows

• 下載安裝包
• 解壓安裝包拷貝到windows下的C:\Program Files下面並重命名文件夾爲filebeat
• 以管理員運行powershell
• 執行

cd 'C:\Program Files\Filebeat'
set-executionpolicy remotesigned
.\install-service-filebeat.ps1

• 這樣就將filebeat註冊爲系統服務。
  

3，linux

• 以centos7爲例，執行以下的命令

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.1.1-x86_64.rpm
sudo rpm -vi filebeat-6.1.1-x86_64.rpm

• 檢查安裝

[root@docker83 ~]# filebeat -version
filebeat version 6.1.1 (amd64), libbeat 6.1.1

4，配置filebeat

1）filebeat模塊

Filebeat提供了一組預構建模塊，您可以使用這些模塊快速實現和部署日誌監控解決方案，在大約5分鐘內完成示例儀表板和數據可視化。這些模塊支持常見的日誌格式，如Nginx、Apache2和MySQL，並且可以通過發出簡單的命令來運行.

2）安裝filebeat模塊

#安裝完畢重啓Elasticsearch
cd /opt/elasticsearch-6.1.1/bin
./elasticsearch-plugin install ingest-geoip
./elasticsearch-plugin install ingest-user-agent

3）配置filebeat

###################### 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 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.

- type: log

  # Change to true to enable this prospector configuration.
  enabled: true

  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    - D:\apache-tomcat-7.0.77\logs\*
    #- 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

  # 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


#============================= 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

#================================ 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


#============================== Dashboards =====================================
# These settings control loading the sample dashboards to the Kibana index. Loading
# the dashboards is disabled by default and can be enabled either by setting the
# options here, or by using the `-setup` CLI flag or the `setup` command.
setup.dashboards.enabled: true 

# 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
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.
#setup.dashboards.url:

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

# 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"

#============================= Elastic Cloud ==================================

# These settings simplify using filebeat with the Elastic Cloud (https://cloud.elastic.co/).

# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:

# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.
#cloud.auth:

#================================ 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"]
output.logstash:
  hosts: ["192.168.8.83:5044"]

setup.kibana:
  host: "192.168.8.83:5601"

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

#----------------------------- 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"

#================================ 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: ["*"]
