# bind an address of this host
# empty for bind all addresses of this host
bind_addr=
# bind_addr= 后面为绑定的IP地址 (常用于服务器有多个IP但只希望一个IP提供服务)。如果不填则表示所有的(一般不填就OK)
# the tracker server port
port=22122

# 1. group_name：所属组名
# 2. ip_addr：ip地址
# 3. status：状态
# 4. sync_src_ip_addr：向该storage server同步已有数据文件的源服务器
# 5. sync_until_timestamp：同步已有数据文件的截至时间（UNIX时间戳）
# 6. stat.total_upload_count：上传文件次数
# 7. stat.success_upload_count：成功上传文件次数
# 8. stat.total_set_meta_count：更改meta data次数
