以上是我的Laravel独白示例日志数据。我正在使用 Logstash 读取日志数据并将其发送到 Elasticsearch。下面是我的 logstash.conf 文件

input {
  file {
    path => '/var/www/html/php-app/application/storage/logs/laravel-*.log'
    start_position => 'beginning'
    ignore_older => 0
  }
}
filter {
  grok {
    match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}\] %{DATA:env}\.%{DATA:severity}: %{DATA:message}at %{DATA:trace}" }
  }
}
output {
  elasticsearch {
    hosts => [ 'localhost:9200' ]
    index => "laravel-%{+YYYY-MM-dd}"
  }
  stdout {
    codec => rubydebug
  }
}

以上配置适用于单行日志消息。例如下面的日志消息

[2018-02-12 09:15:43] development.WARNING: home page

生成输出为

"timestamp": "2018-02-12 10:57:25",
"@timestamp": "2018-02-12T10:57:26.614Z",
"severity": "INFO",
"path": "/var/www/html/php-app/application/storage/logs/laravel-2018-02-12.log",
"message": "[2018-02-12 10:57:25] development.INFO: home page  ",
"env": "development"

但对于多行消息（即 - 带有堆栈跟踪的消息），它会为每一行生成如下所示。

"@timestamp" => 2018-02-12T10:56:47.785Z,
"path" => "/var/www/html/php-app/application/storage/logs/laravel-2018-02-12.log",
"message" => "#1 /var/www/html/vendor/laravel/framework/src/Illuminate/Pipeline/Pipeline.php(149): Illuminate\\Foundation\\Http\\Middleware\\ValidatePostSize->handle(Object(Illuminate\\Http\\Request), Object(Closure))",
"tags" => [
    [0] "_grokparsefailure"
],

我也试过多行过滤器。多行错误日志仍然没有成功。我需要一个适用于多行和单行错误消息的解决方案。

请帮助我找到适合单行和多行错误日志的正确 grok 配置。

终于！我得到了我的问题的解决方案。并发布将来对其他人有用的 logstash 配置。

input {
    file {
        path => '/var/www/html/php-app/application/storage/logs/laravel-*.log'
        start_position => 'beginning'
        ignore_older => 0
        codec => multiline { pattern => "\[[\d]{4}" negate => "true" what => "previous" }
    }
}

filter {
    grok {
        match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}\] %{DATA:env}\.%{DATA:severity}: %{DATA:message}" }
    }
}

output {
    elasticsearch {
        hosts => [ 'localhost:9200' ]
        index => "laravel-%{+YYYY-MM-dd}"
    }
    stdout {
        codec => rubydebug
    }
}
