Question

我正在使用filebeat-6.5.1，Logstash-6.5.1和elasticsearch-6.5.1

我在单个配置文件中使用多个GROK，并尝试将日志发送到Elasticsearch

下面是我的Filebeat.yml

filebeat.prospectors：

type: log
paths:

var/log/message
fields:
type: apache_access
tags: ["ApacheAccessLogs"]
type: log
paths:

var/log/indicate
fields:
type: apache_error
tags: ["ApacheErrorLogs"]
type: log
paths:

var/log/panda
fields:
type: mysql_error
tags: ["MysqlErrorLogs"]
output.logstash:
The Logstash hosts
hosts: ["logstash:5044"]

下面是我的logstash配置文件-

input {
beats {
port => 5044
tags => [ "ApacheAccessLogs", "ApacheErrorLogs", "MysqlErrorLogs" ]
}
}
filter {
if "ApacheAccessLogs" in [tags] {
grok {
match => [
"message" , "%{COMBINEDAPACHELOG}+%{GREEDYDATA:extra_fields}",
"message" , "%{COMMONAPACHELOG}+%{GREEDYDATA:extra_fields}"
]
overwrite => [ "message" ]
}
mutate {
convert => ["response", "integer"]
convert => ["bytes", "integer"]
convert => ["responsetime", "float"]
}
geoip {
source => "clientip"
target => "geoip"
add_tag => [ "apache-geoip" ]
}
date {
match => [ "timestamp" , "dd/MMM/YYYY:HH:mm:ss Z" ]
remove_field => [ "timestamp" ]
}
useragent {
source => "agent"
}
}
if "ApacheErrorLogs" in [tags] {
grok {
match => { "message" => ["[%{APACHE_TIME:[apache2][error][timestamp]}] [%{LOGLEVEL:[apache2][error][level]}]( [client %{IPORHOST:[apache2][error][client]}])? %{GREEDYDATA:[apache2][error][message]}",
"[%{APACHE_TIME:[apache2][error][timestamp]}] [%{DATA:[apache2][error][module]}:%{LOGLEVEL:[apache2][error][level]}] [pid %{NUMBER:[apache2][error][pid]}(:tid %{NUMBER:[apache2][error][tid]})?]( [client %{IPORHOST:[apache2][error][client]}])? %{GREEDYDATA:[apache2][error][message1]}" ] }
pattern_definitions => {
"APACHE_TIME" => "%{DAY} %{MONTH} %{MONTHDAY} %{TIME} %{YEAR}"
}
remove_field => "message"
}
mutate {
rename => { "[apache2][error][message1]" => "[apache2][error][message]" }
}
date {
match => [ "[apache2][error][timestamp]", "EEE MMM dd H:m:s YYYY", "EEE MMM dd H:m:s.SSSSSS YYYY" ]
remove_field => "[apache2][error][timestamp]"
}
}
if "MysqlErrorLogs" in [tags] {
grok {
match => { "message" => ["%{LOCALDATETIME:[mysql][error][timestamp]} ([%{DATA:[mysql][error][level]}] )?%{GREEDYDATA:[mysql][error][message]}",
"%{TIMESTAMP_ISO8601:[mysql][error][timestamp]} %{NUMBER:[mysql][error][thread_id]} [%{DATA:[mysql][error][level]}] %{GREEDYDATA:[mysql][error][message1]}",
"%{GREEDYDATA:[mysql][error][message2]}"] }
pattern_definitions => {
"LOCALDATETIME" => "[0-9]+ %{TIME}"
}
remove_field => "message"
}
mutate {
rename => { "[mysql][error][message1]" => "[mysql][error][message]" }
}
mutate {
rename => { "[mysql][error][message2]" => "[mysql][error][message]" }
}
date {
match => [ "[mysql][error][timestamp]", "ISO8601", "YYMMdd H:m:s" ]
remove_field => "[apache2][access][time]"
}
}
}

output {
if "ApacheAccessLogs" in [tags] {
elasticsearch { hosts => ["elasticsearch:9200"]
index => "apache"
document_id => "apacheaccess"
}
}
if "ApacheErrorLogs" in [tags] {
elasticsearch { hosts => ["elasticsearch:9200"]
index => "apache"
document_id => "apacheerror"
}
}
if "MysqlErrorLogs" in [tags] {
elasticsearch { hosts => ["elasticsearch:9200"]
index => "apache"
document_id => "sqlerror"
}
}
stdout { codec => rubydebug }
}

数据被发送到弹性搜索，但是对于同一索引中的每个document_id仅创建了3条记录。

仅创建3条记录，并将每条新输入的日志覆盖到相同的document_id上，而旧的将丢失。

你们能帮我吗？

document_id的定义是为事件提供唯一的文档ID。在您的情况下，由于它们是静态的（ apacheaccess ， apacheerror ， sqlerror ），因此每个索引中只有1个事件被吸收到elasticsearch中，覆盖最新事件。

由于您有3种不同的数据类型，因此您似乎在为每种事件类型（ApacheAccessLogs，ApacheErrorLogs，MysqlErrorLogs）提供不同的索引，如下所示：

output {
  if "ApacheAccessLogs" in [tags] {
    elasticsearch {
      hosts => ["elasticsearch:9200"]
      index => "apache-access"
    }
  }
  if "ApacheErrorLogs" in [tags] {
    elasticsearch {
      hosts => ["elasticsearch:9200"]
      index => "apache-error"
    }
  }
  if "MysqlErrorLogs" in [tags] {
    elasticsearch {
      hosts => ["elasticsearch:9200"]
      index => "mysql-error"
    }
  }
  stdout {
    codec => rubydebug
  }
}

在很多情况下，您不需要手动设置ID（例如，在获取数据的情况下），因为Logstash和Elasticsearch会自行进行管理。

但是，如果是这种情况，并且您不能使用一个字段来单独标识每个事件，则可以使用为此专门设计的logstash-filter-fingerprint。

日志将在相同的_id下的指定索引中覆盖
