################### 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
