export   #導出
run      #執行（默認執行）
test     #測試配置
keystore #秘鑰存儲
modules  #模組配置管理
setup    #設置初始環境

創建一個存儲密碼的keystore：filebeat keystore create
然後往其中添加鍵值對，例如：filebeatk eystore add ES_PWD
使用覆蓋原來鍵的值：filebeat key store add ES_PWD–force
刪除鍵值對：filebeat key store remove ES_PWD
查看已有的鍵值對：filebeat key store list

type: log #input類型為log
enable: true #表示是該log類型配置生效
paths：     #指定要監控的日誌，目前按照Go語言的glob函數處理。沒有對配置目錄做遞歸處理，比如配置的如果是：
- /var/log/* /*.log  #則只會去/var/log目錄的所有子目錄中尋找以".log"結尾的文件，而不會尋找/var/log目錄下以".log"結尾的文件。
recursive_glob.enabled: #啟用全局遞歸模式，例如/foo/**包括/foo, /foo/*, /foo/*/*
encoding：#指定被監控的文件的編碼類型，使用plain和utf-8都是可以處理中文日誌的
exclude_lines: ['^DBG'] #不包含匹配正則的行
include_lines: ['^ERR', '^WARN']  #包含匹配正則的行
harvester_buffer_size: 16384 #每個harvester在獲取文件時使用的緩衝區的位元組大小
max_bytes: 10485760 #單個日誌消息可以擁有的最大位元組數。max_bytes之後的所有位元組都被丟棄而不發送。默認值為10MB (10485760)
exclude_files: ['\.gz$']  #用於匹配希望Filebeat忽略的文件的正則表達式列表
ingore_older: 0 #默認為0，表示禁用，可以配置2h，2m等，注意ignore_older必須大於close_inactive的值.表示忽略超過設置值未更新的
文件或者文件從來沒有被harvester收集
close_* #close_ *配置選項用於在特定標準或時間之後關閉harvester。 關閉harvester意味著關閉文件處理程式。 如果在harvester關閉
後文件被更新，則在scan_frequency過後，文件將被重新拾取。 但是，如果在harvester關閉時移動或刪除文件，Filebeat將無法再次接收文件
，並且harvester未讀取的任何數據都將丟失。
close_inactive  #啟動選項時，如果在制定時間沒有被讀取，將關閉文件句柄
讀取的最後一條日誌定義為下一次讀取的起始點，而不是基於文件的修改時間
如果關閉的文件發生變化，一個新的harverster將在scan_frequency運行後被啟動
建議至少設置一個大於讀取日誌頻率的值，配置多個prospector來實現針對不同更新速度的日誌文件
使用內部時間戳機制，來反映記錄日誌的讀取，每次讀取到最後一行日誌時開始倒計時使用2h 5m 來表示
close_rename #當選項啟動，如果文件被重命名和移動，filebeat關閉文件的處理讀取
close_removed #當選項啟動，文件被刪除時，filebeat關閉文件的處理讀取這個選項啟動後，必須啟動clean_removed
close_eof #適合只寫一次日誌的文件，然後filebeat關閉文件的處理讀取
close_timeout #當選項啟動時，filebeat會給每個harvester設置預定義時間，不管這個文件是否被讀取，達到設定時間後，將被關閉
close_timeout 不能等於ignore_older,會導致文件更新時，不會被讀取如果output一直沒有輸出日誌事件，這個timeout是不會被啟動的，
至少要要有一個事件發送，然後haverter將被關閉
設置0 表示不啟動
clean_inactived #從註冊表文件中刪除先前收穫的文件的狀態
設置必須大於ignore_older+scan_frequency，以確保在文件仍在收集時沒有刪除任何狀態
配置選項有助於減小註冊表文件的大小，特別是如果每天都生成大量的新文件
此配置選項也可用於防止在Linux上重用inode的Filebeat問題
clean_removed #啟動選項後，如果文件在磁碟上找不到，將從註冊表中清除filebeat
如果關閉close removed 必須關閉clean removed
scan_frequency #prospector檢查指定用於收穫的路徑中的新文件的頻率,默認10s
tail_files：#如果設置為true，Filebeat從文件尾開始監控文件新增內容，把新增的每一行文件作為一個事件依次發送，
而不是從文件開始處重新發送所有內容。
symlinks：#符號鏈接選項允許Filebeat除常規文件外,可以收集符號鏈接。收集符號鏈接時，即使報告了符號鏈接的路徑，
Filebeat也會打開並讀取原始文件。
backoff： #backoff選項指定Filebeat如何積極地抓取新文件進行更新。默認1s，backoff選項定義Filebeat在達到EOF之後
再次檢查文件之間等待的時間。
max_backoff： #在達到EOF之後再次檢查文件之前Filebeat等待的最長時間
backoff_factor： #指定backoff嘗試等待時間幾次，默認是2
harvester_limit：#harvester_limit選項限制一個prospector並行啟動的harvester數量，直接影響文件打開數

tags #列表中添加標籤，用過過濾，例如：tags: ["json"]
fields #可選欄位，選擇額外的欄位進行輸出可以是標量值，元組，字典等嵌套類型
默認在sub-dictionary位置
filebeat.inputs:
fields:
app_id: query_engine_12
fields_under_root #如果值為ture，那麼fields存儲在輸出文檔的頂級位置

multiline.pattern #必須匹配的regexp模式
multiline.negate #定義上面的模式匹配條件的動作是 否定的，默認是false
假如模式匹配條件'^b'，默認是false模式，表示講按照模式匹配進行匹配 將不是以b開頭的日誌行進行合併
如果是true，表示將不以b開頭的日誌行進行合併
multiline.match # 指定Filebeat如何將匹配行組合成事件,在之前或者之後，取決於上面所指定的negate
multiline.max_lines #可以組合成一個事件的最大行數，超過將丟棄，默認500
multiline.timeout #定義超時時間，如果開始一個新的事件在超時時間內沒有發現匹配，也將發送日誌，默認是5s
max_procs #設置可以同時執行的最大CPU數。默認值為系統中可用的邏輯CPU的數量。
name #為該filebeat指定名字，默認為主機的hostname

  # 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.
