通过分析tsdb文件及net.opentsdb.tools.UidManager的runCommand方法：

case $1 in
  (fsck)
    MAINCLASS=Fsck
    ;;
  (import)
    MAINCLASS=TextImporter
    ;;
  (mkmetric)
    shift
    set uid assign metrics "$@"
    MAINCLASS=UidManager
    ;;
  (query)
    MAINCLASS=CliQuery
    ;;
  (tsd)
    MAINCLASS=TSDMain
    ;;
  (scan)
    MAINCLASS=DumpSeries
    ;;
  (uid)
    MAINCLASS=UidManager
    ;;
  (*)
    echo >&2 "$me: error: unknown command '$1'"
    usage
    ;;
esac
shift

可以看出还可在shell命令行执行如下等操作：

./tsdb uid grep metrics t           查询

./tsdb uid rename metrics t1 t11    更名

./tsdb uid fsck                   表数据检查
