如何解析流线输入的多行Java错误/异常堆栈跟踪(我应该通过Kibana看到相同的错误/异常堆栈跟踪)

问题描述 投票:1回答:1

我正在使用EFK。

有人可以在此处提供有关如何通过流利的方法解析多行Java堆栈跟踪以在日志消息字段中推送整个stacktrace的帮助(我应该通过Kibana看到相同的ERROR / Exception stacktrace)。

我需要解析以下错误堆栈跟踪:

2019-06-10 16:51:48.789  INFO 11360 --- [ost-startStop-1] o.s.web.context.ContextLoader            : Root WebApplicationContext: initialization completed in 6293 ms
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
2019-06-10 16:51:52.633 ERROR 11360 --- [ost-startStop-1] o.a.tomcat.jdbc.pool.ConnectionPool      : Unable to create initial connections of pool.
java.sql.SQLException: Access denied for user 'root'@'ec2-13-233-117-154.ap-south-1.compute.amazonaws.com' (using password: YES)
        at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129) ~[mysql-connector-java-8.0.15.jar:8.0.15]
        at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:97) ~[mysql-connector-java-8.0.15.jar:8.0.15]

我的fluent.conf文件配置如下:

# fluentd/conf/fluent.conf
<source>
  @type forward
  port 24224
  bind 0.0.0.0
  <parse>
    @type multiline
    format_firstline /\d{4}-\d{1,2}-\d{1,2}/
    format /(?<time>[^ ]* [^ ]*) (?<path>[^ ]*) (?<method>[^ ]*) (?<message>[^ ](.*?(\n)).*$)/
  </parse>
</source>

<match **>
  #@type copy
  @type detect_exceptions
  <store>
   @type elasticsearch
   host elasticsearch
   port 9200
   logstash_format true
   logstash_prefix fluentd
   logstash_dateformat %Y%m%d
   include_tag_key true
   type_name access_log
   tag_key @log_name
   flush_interval 1s
  </store>
</match>

尝试了以下3种插件,但是我没有获得所需的输入:

fluent-plugin-detect-exceptions-with-error-0.0.3
fluent-plugin-detect-exceptions-0.0.12
fluent-plugin-concat-2.4.0

当我使用上述配置时,我在流畅的容器日志中收到以下错误:

2019-08-02 12:46:23 +0000 [error]: config error file="/fluentd/etc/fluent.conf" error_class=Fluent::ConfigError error="Unknown output plugin 'detect_exceptions'. Run 'gem search -rd fluent-plugin' to find plugins"

java multiline fluentd

请确保您已安装插件。您可以使用以下命令安装它

gem install fluent-plugin-detect-exceptions 

我在代理上使用以下配置。请注意,在检查消息是否为堆栈跟踪之前,我使用fluent-plugin-rewrite-tag-filter进行了重新标记。

<match tag>
  @type                       rewrite_tag_filter
  <rule>
    key                       container_id
    pattern                   /(.+)/
    tag                       removeme.${tag}.$1
  </rule>
</match>

<match removeme**>
  @type detect_exceptions
  remove_tag_prefix           removeme
  message                     message
  languages                   java, python
  multiline_flush_interval    1
</match>

<match tag_without_prefix**>
  @type                       elasticsearch
  host                        elasticsearch
  port                        9200
  logstash_format             true
  ...
</match>

或者您可以在此示例中使用@label参数:https://github.com/GoogleCloudPlatform/fluent-plugin-detect-exceptions/issues/19#issuecomment-406628486
