hblog 是一个日志集群分析器。支持的体制格式有：Syslog、 Log4j、Java GC log。
Usage: hblog [OPTIONS]... [TIER...] [TIER:HOST...] Where TIER is one of: dfs-nn hbase-master-gc mr-jt dfs-nn-gc hbase-regionservers mr-jt-gc dfs-slaves hbase-regionservers-gc mr-slaves dfs-slaves-gc hbase-secondary mr-slaves-gc dfs-sn hbase-secondary-gc syslog dfs-sn-gc hbase-thrift hbase-master hbase-zookeepers hblog - a log paser for clusters Options: -h, --help show this help message and exit -v, --verbose print extra information about the state of hblog -n, --nowrap print characters only up to the width of your terminal Modes: Log lines are "fingerprinted", usually able to assign matching fingerprints to log lines that differ only by timestamp, specific host names, or other variables. --summary host-vs-fingerprint frequency table (Default mode) -d, --details print all matching log lines embellished with hostnames and fingerprints -f, --follow like --details but streaming, just like 'tail -f' Select time: If time selectors are not supplied, only the last one minute of logs will be processed. -s START, --start=START process only lines after the time specified in format YYYY-MM-DD hh:mm:ss -e END, --end=END process only lines up to the time specified in format YYYY-MM-DD hh:mm:ss -t TAIL, --tail=TAIL process only the last X minutes of each log specified as one of these formats ":sec", "min", "hour:min" -T TAIL_END, --tail-end=TAIL_END process only up to the last X minutes of each log specified as one of these formats ":sec", "min", "hour:min" Filters: -l LEVEL, --level=LEVEL the log level to filter for (default level: WARN) -S SAMPLE, --sample=SAMPLE sampling rate will be achieved by skipping log lines (default: 1.0, read all lines) -p FP, --fp=FP comma-separated list of fingerprints to include -P FP_EXCLUDE, --fp-exclude=FP_EXCLUDE comma-separated list of fingerprints to exclude -r RE, --re=RE comma-separated list of regex to include (case insensitive) -R RE_EXCLUDE, --re-exclude=RE_EXCLUDE comma-separated list of regex to exclude (case insensitive) --local To test hblog. Connect to localhost. Read logs from ./var/log/hadoop-example.log
具有以下功能：
-
Remote access to logs via a single CLI
-
Multi-host summaries of log line frequencies
-
Multi-host realtime tailing (like tail -f)
