我用flume-ng 1.5版本收集日誌。水槽損失數據當收集在線數據到hdfs
數據流中有兩個代理，它們分別位於兩臺主機上。
並且從代理1到代理2發送數據。
藥劑的成分如下：
AGENT1：假脫機目錄源 - >文件信道 - >阿夫羅下沉
agent2：阿夫羅源 - >文件信道 - > HDFS水槽
但是，它似乎損失數據約百萬分之一百萬的數據。 爲了解決問題，我試過下列步驟操作：
- 查找代理日誌：找不到任何錯誤或異常。
- 查找代理監控指標：從通道中獲取的事件數始終等於
- 分別通過hive查詢和hdfs文件使用shell統計數據數：兩個數相等且小於在線數據數
AGENT1的配置：
#agent
agent1.sources = src_spooldir
agent1.channels = chan_file
agent1.sinks = sink_avro
#source
agent1.sources.src_spooldir.type = spooldir
agent1.sources.src_spooldir.spoolDir = /data/logs/flume-spooldir
agent1.sources.src_spooldir.interceptors=i1
#interceptors
agent1.sources.src_spooldir.interceptors.i1.type=regex_extractor
agent1.sources.src_spooldir.interceptors.i1.regex=(\\d{4}-\\d{2}-\\d{2}).*
agent1.sources.src_spooldir.interceptors.i1.serializers=s1
agent1.sources.src_spooldir.interceptors.i1.serializers.s1.name=dt
#sink
agent1.sinks.sink_avro.type = avro
agent1.sinks.sink_avro.hostname = 10.235.2.212
agent1.sinks.sink_avro.port = 9910
#channel
agent1.channels.chan_file.type = file
agent1.channels.chan_file.checkpointDir = /data/flume/agent1/checkpoint
agent1.channels.chan_file.dataDirs = /data/flume/agent1/data
agent1.sources.src_spooldir.channels = chan_file
agent1.sinks.sink_avro.channel = chan_file
agent2的配置
# agent
agent2.sources = source1
agent2.channels = channel1
agent2.sinks = sink1
# source
agent2.sources.source1.type = avro
agent2.sources.source1.bind = 10.235.2.212
agent2.sources.source1.port = 9910
# sink
agent2.sinks.sink1.type= hdfs
agent2.sinks.sink1.hdfs.fileType = DataStream
agent2.sinks.sink1.hdfs.filePrefix = log
agent2.sinks.sink1.hdfs.path = hdfs://hnd.hadoop.jsh:8020/data/%{dt}
agent2.sinks.sink1.hdfs.rollInterval = 600
agent2.sinks.sink1.hdfs.rollSize = 0
agent2.sinks.sink1.hdfs.rollCount = 0
agent2.sinks.sink1.hdfs.idleTimeout = 300
agent2.sinks.sink1.hdfs.round = true
agent2.sinks.sink1.hdfs.roundValue = 10
agent2.sinks.sink1.hdfs.roundUnit = minute
# channel
agent2.channels.channel1.type = file
agent2.channels.channel1.checkpointDir = /data/flume/agent2/checkpoint
agent2.channels.channel1.dataDirs = /data/flume/agent2/data
agent2.sinks.sink1.channel = channel1
agent2.sources.source1.channels = channel1
歡迎任何建議！
