如题，笔者进一家新公司的时候，这家公司要求搭建一套新的企业级elk，之前也没自己搭建过，摸着石头过河，好在最后搭建好并投入使用。

        刚开始想法还是比较简单，先搭起来在说，后期慢慢优化慢慢调，笔者用的是elk+filebeat+kafka架构，这方面不是很懂，到最后filebeat采集日志的时候傻眼了，刚登陆测试服务器，发现一个服务器上有几十个需要采集的日志，这个要怎么采集到elk集群中呢，filebeat修改了无数次，es收集到的索引还是2个，要么就是融合了全部日志，没有错，就是一个索引！这可达不到生产要求，后续一边测试一遍实验，还是试出来了，多个日志目录下的多个日志文件，分别根据不同的日期生成不同的索引，索引名以服务器名+模块名+日期构成，这样es上的索引一目了然，见名知义。

        filebeat大致的配置文件如下：

   

###################### 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
enabled: true
paths:
- /mnt/test/test.log
fields:
source: account
- type: log
enabled: true
paths:
- /mnt/test2/test2.log
fields:
source: member
#- 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

# 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: 1
#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` 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: "192.168.20.9"
# 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 ------------------------------
setup.template.enabled: true
setup.template.fields: fields.yml
setup.template.overwrite: true
setup.template.name: "wlyy_log"
setup.template.pattern: "wlyy-*"
setup.ilm.enabled: false
output.elasticsearch:
#index: "mylog-seventh-%{+yyyy.MM.dd}"
# Array of hosts to connect to.
#hosts: ["192.168.20.9:9200"]
hosts: ["192.168.20.9:9200","192.168.20.8:9202","192.168.20.7:9201"]
index: "wlyy-%{[fields.source]}-*"
indices:
- index: "wlyy-account-%{+yyyy.MM.dd}"
when.equals:
fields:
source: "account"
- index: "wlyy-member-%{+yyyy.MM.dd}"
when.equals:
fields:
source: "member"
# Optional protocol and basic auth credentials.
#protocol: "https"
username: "elastic"
password: "elastic"

#----------------------------- 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: ["*"]

#============================== X-Pack 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.
#monitoring.enabled: false

# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch
# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.
#monitoring.cluster_uuid:

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch
# output configuration, so if you have the Elasticsearch output configured such
# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.
#monitoring.elasticsearch:

#================================= Migration ==================================

# This allows to enable 6.7 migration aliases
#migration.6_to_7.enabled: true

 

 

 

 

    需要采集的日志是/mnt/test/test.log  和/mnt/test2/test2.log  在filebeat配置文件inputs部分，添加对应的2个fields（注意yml格式，对齐与缩进） fields下有2个值，分别是account跟member。

 

 在output部分，注意索引模板名跟下面的index名字对应的匹配规则，否则会失败。

 

    

经过这样的配置，filebeat就能够按照指定的名称和命名规则，根据不同的模块生成不同的索引。（笔者这里是根据日期生成索引）
