ELK实践 | kibana

一、ElasticSearch+FileBeat+Kibana搭建平台

在C# 里面运行程序，输出日志（xxx.log 文本文件）到FileBeat配置的路径下面。

平台搭建，参考之前的随笔。

FileBeat配置如下：

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

- type: log

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

  #paths:

    #- E:\filebeat-6.6.2-windows-x86_64\data\logstash-tutorial.log\*.log

    #- c:\programdata\elasticsearch\logs\*

  paths:

    - E:\ELKLog\log\*.log

#- type: redis

  #hosts: ["localhost:6379"]

  #password: "hy900511@"

  # Change to true to enable this input configuration.

  enabled: true

  #scan_frequency: 5s

  # 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: 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: 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

# 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"

  # 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:

#============================= 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"]

  # Enabled ilm (beta) to use index lifecycle management instead daily indices.

  #ilm.enabled: false

  # 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"

#================================ Processors =====================================

# Configure processors to enhance or manipulate events generated by the beat.

processors:

  - add_host_metadata: ~

  - add_cloud_metadata: ~

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

# Sets log level. The default log level is info.

# Available log levels are: 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: ["*"]

#============================== Xpack 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.

#xpack.monitoring.enabled: false

# Uncomment to send the metrics to Elasticsearch. Most settings from the

# Elasticsearch output are accepted here as well. Any setting that is not set is

# automatically inherited from the Elasticsearch output configuration, so if you

# have the Elasticsearch output configured, you can simply uncomment the

# following line.

#xpack.monitoring.elasticsearch:

以上程序都在服务启动着。

然后在C#中，执行程序将日志保存到 E:\ELKLog\log\

【注意：Filebeat是以行来识别日志的更改，所以将日志的同一段话以行写入】

在Kibana中看到：

ELK实践-LMLPHP

_source字段拆分需要用到logstash。

二、配置Filebeat多行合并

一些错误日志，都是自动换行的。不配置的话本来是一条日志的，在ES中就显示成了多条

于是配置multiline参数;

以Time开头的行是一条完整日志的开始，它和后面多个不以Time开头的行组成一条完整日志；【因为我的日志message都是以Time= 开头，所以这样配置】

参考：应该怎样正确配置filebeat文件（包括multiline、input_type等）
