标签： logstash kibana elastic-stack logstash-configuration filebeat

尝试使用Filebeats，Logstash设置简单的日志记录，并能够在Kibana中查看日志。使用log4net作为记录器运行一个简单的mvc .net核心应用程序。 log4net FileAppender将日志附加到C：\ Logs \ Debug.log就可以了。但是无法将它们推送到Kibana。

基于此here条款，我将设置文件信号，然后通过logstash转换日志并能够在Kibana中查看我的日志。

  1. logstash.yml 

- module: logstash
  # logs
  log:
    enabled: true
    #var.paths: ["C:/Logs/Debug.log"] - THIS CAUSES ERRROS - should this be UNCOMMENTED?
    
    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

  # Slow logs
  slowlog:
   enabled: true
    #var.paths: ["C:/Logs/Debug.log"]

    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

  1. logstash-sample.conf 

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input { 
    file {
        path => "C:\Logs\Debug.log"
	type => "log4net"
        codec => multiline {
                    pattern => "^(DEBUG|WARN|ERROR|INFO|FATAL)"
                    negate => true
                    what => previous
                }
      }
}
filter {
  if [type] == "log4net" {
    grok {
      match => [ "message", "(?m)%{LOGLEVEL:level} %{TIMESTAMP_ISO8601:sourceTimestamp} %{DATA:logger} \[%{NUMBER:threadId}\]  \[%{IPORHOST:tempHost}\] %{GREEDYDATA:tempMessage}" ]
    }
    mutate {
        replace => [ "message" , "%{tempMessage}" ]
        replace => [ "host" , "%{tempHost}" ]
        remove_field => [ "tempMessage" ]
        remove_field => [ "tempHost" ]
    }
  }
}
output {
  elasticsearch {
    host => localhost
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    #user => "elastic"
    #password => "changeme"
  }
}

使用配置示例输出运行logstash： enter image description here

  1. Filebeat.yml 

###################### 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

  # Change to true to enable this input configuration.
  enabled: false

  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    #- /var/log/*.log
    - c:\Logs\*.log

  # 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:
  host: "localhost:5601"

  # 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:

我看到我的mvc应用程序在C：\ Logs \ Debug.log中记录的日志（log4net）很好，但是无法进行设置，因此这些内容都显示在Kibana中。 我将如何设置它以便在Kibana中看到我的日志？

  }
}
filter {
  grok {      
      match => { "message" => "(?m)^%{TIMESTAMP_ISO8601:timestamp}~~\[%{DATA:thread}\]~~\[%{DATA:user}\]~~\[%{DATA:requestId}\]~~\[%{DATA:userHost}\]~~\[%{DATA:requestUrl}\]~~%{DATA:level}~~%{DATA:logger}~~%{DATA:logmessage}~~%{DATA:exception}\|\|" }

# 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

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

#----------------------------- Logstash output --------------------------------
output.logstash:

我启用了文件信号/将其作为服务运行。还会运行logstash（请参阅下面的Powershell窗口）。当我更改Debug.log文件中的任何内容并保存时，我会立即看到这些更改输出到控制台。

但是，当我转到仪表板时，仍然看不到任何日志。我究竟做错了什么？ enter image description here

我能够解决这个问题。使用Log4Net登录.net Core 2.0。 1.像往常一样设置您的log4net（确保您的日志记录有效，并且您的日志已写入某些日志文件=>对我来说是C：\ Logs \ Debug.log“

  1. 安装Kibana，Elasticsearch，Logstash和Filebeat：https://www.elastic.co/start
  2. 配置filebeat.yml

filebeat.inputs：

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

filebeat.inputs:

- type: log

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

  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    #- /var/log/*.log
    - c:\Logs\*.log


  multiline.pattern: '^(\d{4}-\d{2}-\d{2}\s)'

  multiline.negate: true

  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

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

# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:
  host: "localhost:5601"


#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch: => MAKE SURE THIS IS COMMENTED OUT 
  # Array of hosts to connect to.
#  hosts: ["localhost:9200"]

  #ilm.enabled: false

  # Optional protocol and basic auth credentials.

  #password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
  hosts: ["localhost:5044"]


processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~

  1. logstash.yml 

- module: logstash
  # logs
  log:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths: -C:\Logs\*.log
    
    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

  # Slow logs
  slowlog:
   enabled: true
    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths: C:\Logs\*.log

    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

  1. logstash.conf 

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  beats {
    port => 5044
  }
}
filter {
  grok {      
      match => { "message" => "(?m)^%{TIMESTAMP_ISO8601:timestamp}~~\[%{DATA:thread}\]~~\[%{DATA:user}\]~~\[%{DATA:requestId}\]~~\[%{DATA:userHost}\]~~\[%{DATA:requestUrl}\]~~%{DATA:level}~~%{DATA:logger}~~%{DATA:logmessage}~~%{DATA:exception}\|\|" }
      add_field => { 
        "received_at" => "%{@timestamp}" 
        "received_from" => "%{host}"
      }
      remove_field => ["message"]      
    }
  date {
    match => [ "timestamp", "yyyy-MM-dd HH:mm:ss:SSS" ]
  }
}
output {
  elasticsearch {
	hosts => ["http://localhost:9200"]
	sniffing => true
    index => "filebeat-%{+YYYY.MM.dd}"
	document_type => "%{[@metadata][type]}"
    #user => "elastic"
    #password => "changeme"
  }
  stdout { codec => rubydebug }
}

  1. 确保logstash正在使用此配置（CMD）运行：

    \ bin \ logstash -f c：\ Elastic \ Logstash \ config \ logstash.conf

  2. 打开您的日志文件（C：\ Logs \ Debug.log）并添加一些内容。您应该在运行logstash并提取数据的powershell输出窗口中看到输出： enter image description here

  3. 打开Kibana并转到已写入的索引（logstash.conf） index =>“ filebeat-％{+ YYYY.MM.dd}”
