################### Filebeat Configuration Example #########################

############################# Filebeat ######################################

filebeat:

  # List of prospectors to fetch data.

  prospectors:

    # Each - is a prospector. Below are the prospector specific configurations

    -

      # Paths that should be crawled and fetched. Glob based paths.

      # To fetch all ".log" files from a specific level of subdirectories

      # /var/log/*/*.log can be used.

      # For each file found under this path, a harvester is started.

      # Make sure not file is defined twice as this can lead to unexpected behaviour.

      # 指定要监控的日志，可以指定具体得文件或者目录

      paths:

        - /var/log/*.log  （这是默认的）（自行可以修改）(比如我放在/home/hadoop/app.log里）

        #- c:\programdata\elasticsearch\logs\*

      # Configure the file encoding for reading files with international characters

      # following the W3C recommendation for HTML5 (http://www.w3.org/TR/encoding).

      # Some sample encodings:

      #  plain, utf-8, utf-16be-bom, utf-16be, utf-16le, big5, gb18030, gbk,

      #    hz-gb-2312, euc-kr, euc-jp, iso-2022-jp, shift-jis, ...

      # 指定被监控的文件的编码类型，使用plain和utf-8都是可以处理中文日志的

      #encoding: plain

      # Type of the files. Based on this the way the file is read is decided.

      # The different types cannot be mixed in one prospector

      #

      # Possible options are:

      # * log: Reads every line of the log file (default)

      # * stdin: Reads the standard in

      # 指定文件的输入类型log(默认)或者stdin

      input_type: log

      # Exclude lines. A list of regular expressions to match. It drops the lines that are

      # matching any regular expression from the list. The include_lines is called before

      # 在输入中排除符合正则表达式列表的那些行。

      # exclude_lines. By default, no lines are dropped.

      # 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. The include_lines is called before

      # exclude_lines. By default, all the lines are exported.

      # 包含输入中符合正则表达式列表的那些行（默认包含所有行），include_lines执行完毕之后会执行exclude_lines

      # 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.

      # 忽略掉符合正则表达式列表的文件

      # exclude_files: [".gz$"]

      # Optional additional fields. These field can be freely picked

      # to add additional information to the crawled log files for filtering

      # 向输出的每一条日志添加额外的信息，比如“level:debug”，方便后续对日志进行分组统计。

      # 默认情况下，会在输出信息的fields子目录下以指定的新增fields建立子目录，例如fields.level

      # 这个得意思就是会在es中多添加一个字段，格式为 "filelds":{"level":"debug"}

      #fields:

      #  level: debug

      #  review: 1

      # Set to true to store the additional fields as top level fields instead

      # of under the "fields" sub-dictionary. In case of name conflicts with the

      # fields added by Filebeat itself, the custom fields overwrite the default

      # fields.

      # 如果该选项设置为true，则新增fields成为顶级目录，而不是将其放在fields目录下。

      # 自定义的field会覆盖filebeat默认的field

      # 如果设置为true，则在es中新增的字段格式为："level":"debug"

      #fields_under_root: false

      # Ignore files which were modified more then the defined timespan in the past.

      # In case all files on your system must be read you can set this value very large.

      # Time strings like 2h (2 hours), 5m (5 minutes) can be used.

      # 可以指定Filebeat忽略指定时间段以外修改的日志内容，比如2h（两个小时）或者5m(5分钟)。

      #ignore_older: 0

      # Close older closes the file handler for which were not modified

      # for longer then close_older

      # Time strings like 2h (2 hours), 5m (5 minutes) can be used.

      # 如果一个文件在某个时间段内没有发生过更新，则关闭监控的文件handle。默认1h

      #close_older: 1h

      # Type to be published in the 'type' field. For Elasticsearch output,

      # the type defines the document type these entries should be stored

      # in. Default: log

      # 设定Elasticsearch输出时的document的type字段 可以用来给日志进行分类。Default: log

      #document_type: log

      # Scan frequency in seconds.

      # How often these files should be checked for changes. In case it is set

      # to 0s, it is done as often as possible. Default: 10s

      # Filebeat以多快的频率去prospector指定的目录下面检测文件更新（比如是否有新增文件）

      # 如果设置为0s，则Filebeat会尽可能快地感知更新（占用的CPU会变高）。默认是10s

      #scan_frequency: 10s

      # Defines the buffer size every harvester uses when fetching the file

      # 每个harvester监控文件时，使用的buffer的大小

      #harvester_buffer_size: 16384

      # Maximum number of bytes a single log event can have

      # All bytes after max_bytes are discarded and not sent. The default is 10MB.

      # This is especially useful for multiline log messages which can get large.

      # 日志文件中增加一行算一个日志事件，max_bytes限制在一次日志事件中最多上传的字节数，多出的字节会被丢弃

      #max_bytes: 10485760

      # Mutiline can be used for log messages spanning multiple lines. This is common

      # for Java Stack Traces or C-Line Continuation

      # 适用于日志中每一条日志占据多行的情况，比如各种语言的报错信息调用栈

      #multiline:

        # The regexp Pattern that has to be matched. The example pattern matches all lines starting with [

        # 多行日志开始的那一行匹配的pattern

        #pattern: ^\[

        # Defines if the pattern set under pattern should be negated or not. Default is false.

        # 是否需要对pattern条件转置使用，不翻转设为true，反转设置为false。  【建议设置为true】

        #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

        # 匹配pattern后，与前面（before）还是后面（after）的内容合并为一条日志

        #match: after

        # The maximum number of lines that are combined to one event.

        # In case there are more the max_lines the additional lines are discarded.

        # Default is 500

        # 合并的最多行数（包含匹配pattern的那一行）

        #max_lines: 500

        # After the defined timeout, an multiline event is sent even if no new pattern was found to start a new event

        # Default is 5s.

        # 到了timeout之后，即使没有匹配一个新的pattern（发生一个新的事件），也把已经匹配的日志事件发送出去

        #timeout: 5s

      # Setting tail_files to true means filebeat starts readding new files at the end

      # instead of the beginning. If this is used in combination with log rotation

      # this can mean that the first entries of a new file are skipped.

      # 如果设置为true，Filebeat从文件尾开始监控文件新增内容，把新增的每一行文件作为一个事件依次发送，

      # 而不是从文件开始处重新发送所有内容

      #tail_files: false

      # Backoff values define how agressively filebeat crawls new files for updates

      # The default values can be used in most cases. Backoff defines how long it is waited

      # to check a file again after EOF is reached. Default is 1s which means the file

      # is checked every second if new lines were added. This leads to a near real time crawling.

      # Every time a new line appears, backoff is reset to the initial value.

      # Filebeat检测到某个文件到了EOF（文件结尾）之后，每次等待多久再去检测文件是否有更新，默认为1s

      #backoff: 1s

      # Max backoff defines what the maximum backoff time is. After having backed off multiple times

      # from checking the files, the waiting time will never exceed max_backoff idenependent of the

      # backoff factor. Having it set to 10s means in the worst case a new line can be added to a log

      # file after having backed off multiple times, it takes a maximum of 10s to read the new line

      # Filebeat检测到某个文件到了EOF之后，等待检测文件更新的最大时间，默认是10秒

      #max_backoff: 10s

      # The backoff factor defines how fast the algorithm backs off. The bigger the backoff factor,

      # the faster the max_backoff value is reached. If this value is set to 1, no backoff will happen.

      # The backoff value will be multiplied each time with the backoff_factor until max_backoff is reached

      # 定义到达max_backoff的速度，默认因子是2，到达max_backoff后，变成每次等待max_backoff那么长的时间才backoff一次，

      # 直到文件有更新才会重置为backoff

      # 根据现在的默认配置是这样的，每隔1s检测一下文件变化，如果连续检测两次之后文件还没有变化，下一次检测间隔时间变为10s

      #backoff_factor: 2

      # This option closes a file, as soon as the file name changes.

      # This config option is recommended on windows only. Filebeat keeps the files it's reading open. This can cause

      # issues when the file is removed, as the file will not be fully removed until also Filebeat closes

      # the reading. Filebeat closes the file handler after ignore_older. During this time no new file with the

      # same name can be created. Turning this feature on the other hand can lead to loss of data

      # on rotate files. It can happen that after file rotation the beginning of the new

      # file is skipped, as the reading starts at the end. We recommend to leave this option on false

      # but lower the ignore_older value to release files faster.

      # 这个选项关闭一个文件,当文件名称的变化。#该配置选项建议只在windows

      #force_close_files: false

    # Additional prospector

    #-

      # Configuration to use stdin input

      #input_type: stdin

  # General filebeat configuration options

  #

  # Event count spool threshold - forces network flush if exceeded

  # spooler的大小，spooler中的事件数量超过这个阈值的时候会清空发送出去（不论是否到达超时时间）

  #spool_size: 2048

  # Enable async publisher pipeline in filebeat (Experimental!)

  # 是否采用异步发送模式（实验功能）

  #publish_async: false

  # Defines how often the spooler is flushed. After idle_timeout the spooler is

  # Flush even though spool_size is not reached.

  # spooler的超时时间，如果到了超时时间，spooler也会清空发送出去（不论是否到达容量的阈值）

  #idle_timeout: 5s

  # Name of the registry file. Per default it is put in the current working

  # directory. In case the working directory is changed after when running

  # filebeat again, indexing starts from the beginning again.

  # 记录filebeat处理日志文件的位置的文件，默认是在启动的根目录下

  #registry_file: .filebeat

  # Full Path to directory with additional prospector configuration files. Each file must end with .yml

  # These config files must have the full filebeat config part inside, but only

  # the prospector part is processed. All global options like spool_size are ignored.

  # The config_dir MUST point to a different directory then where the main filebeat config file is in.

  # 如果要在本配置文件中引入其他位置的配置文件，可以写在这里（需要写完整路径），但是只处理prospector的部分
