filebeat收集日志到es实践

1、环境

操作系统：windows10

elasticsearch：7.14.1

filebeat:7.14.1

elasticsearch-head：5.0.0

2、安装

2.1.安装elasticsearch

官网下载地址：Download Elasticsearch Free | Get Started Now | Elastic | Elastichttps://www.elastic.co/cn/downloads/elasticsearch/你可以根据操作系统选择自己需要的版本，由于本次实践采用的是windows10 64位操作系统，所以选择下载了windows版本的es，将下载的es解压到某个目录下中，在es目录下找到config/elasticsearch.yml文件，修改或者增加如下配置即可，最后cd到bin目录下，在命令窗口执行elasticsearch命令启动服务

network.host: 0.0.0.0

By default Elasticsearch listens for HTTP traffic on the first free port it
finds starting at 9200. Set a specific HTTP port here:
#http.port: 9200

For more information, consult the network module documentation.
--------------------------------- Discovery ----------------------------------
Pass an initial list of hosts to perform discovery when this node is started:
The default list of hosts is ["127.0.0.1", "[::1]"]
#discovery.seed_hosts: ["host1", "host2"]

Bootstrap the cluster using an initial set of master-eligible nodes:
#cluster.initial_master_nodes: ["node-1", "node-2"]

For more information, consult the discovery and cluster formation module documentation.
---------------------------------- Various -----------------------------------
Require explicit names when deleting indices:
#action.destructive_requires_name: true

#关闭机器学习，否则会导致服务无法启动成功

xpack.ml.enabled: false
#xpack.security.enabled: true
discovery.type: single-node

跨域配置
http.cors.enabled: true

http.cors.allow-origin: "*"

node.master: true

node.data: true

2.2.安装elasticsearch-head

elasticsearch-head是一个es的前端控制台，可以通过它预览索引，索引文档数据等等，具体安装步骤，见地址：windows下安装ElasticSearch的Head插件 - 天生一对 - 博客园，安装好后页面访问如下图：

2.3.安装filebeat

官网下载地址：Download Filebeat • Lightweight Log Analysis | Elastichttps://www.elastic.co/cn/downloads/beats/filebeat下载后解压到本地目录，找到目录下的filebeat.yml，做日志收集配置

①日志收集开启和配置收集的日志路径

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.
  # 开启日志收集配置
  enabled: true

  # Paths that should be crawled and fetched. Glob based paths.
  # 收集的应用系统对应的日志路径
  paths:
    - D:developlogsworkflow-engine*.log

②修改索引默认格式，如果不指定的话，会生成filebeat-7.14.1-%{+yyyy.MM.dd}的索引

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

# ---------------------------- Elasticsearch Output ----------------------------
# 配置索引模板的名字和索引模式的格式
setup.template.enabled: false
setup.template.name: "server1"
setup.template.pattern: "server1-*"
# 索引的生命周期，需要禁用，否则可能无法使用自定义的索引名字
setup.ilm.enabled: false
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["localhost:9200"]
  # 输出到那个索引，因为我们这个地方自定义了索引的名字，所以需要上面配置的setup.template.[name|pattern]的配置
  index: "server1-%{+yyyy.MM.dd}"
  enable: true

③使用es的ingest node 的pipeline来处理数据

步骤一：在elasticsearch-head的复合查询tab页，构造pipeline的请求，当返回"acknowledged=true，说明创建成功

发送的内容如下：

{
    "description":"server1 pipeline",
    "processors":[
        {
            "grok":{
                "field":"message",
                "patterns":[
                    "%{TIMESTAMP_ISO8601:createTime} \[%{data:level}\] \[%{data:thread}\] %{data:class} - %{data:content}"
                ]
            },
            "set":{
                "field":"sysCode",
                "value":"server1"
            }
        }
    ]

步骤二：在output.elasticsearch:下增加如下配置，即可

output.elasticsearch:
  pipelines:
    - pipeline: "grok-server1"

步骤三：启动filebeat，.filebeat -e -c filebeat.yml，在es-head查看搜集到数据如下：
