linux – 解释来自/ proc / [id] / mountstats或/ proc / self / mountstats的数据

我想监视我的NFS共享的IO.有很多程序可以解释/ proc / [id] / mountstats([id] = nfs客户端/服务器的id)或/ proc / self / mountstats中的数据.问题是,这些程序每秒计算一些IO.这在命令行中非常好用,但对我的监控解决方案来说却毫无用处.所以我想自己解释mountstats的计数器.我现在的问题是,我需要一些nfs v4的mountstats文档.

到目前为止,我的搜索没有提出任何有用的.

谢谢你的帮助

Ubuntu(nfs客户端)上/ proc / self / mountstats的示例输出：

Format of NFS mountstat

Linux内核版本：2.6.32-358.el6.x86_64

统计的重要文件：

- linux/fs/nfs/super.c: nfs_show_stats
- linux/include/linux/nfs_iostat.h: nfs_stat_eventcounters
- linux/net/sunrpc/stats.c: rpc_print_iostats
- linux/net/sunrpc/xprtsock.c: xs_tcp_print_stats

服务器功能(上限)

>上限：服务器功能
> wtmult：服务器磁盘块大小
> dtsize：readdir大小
> bsize：服务器块大小

nfsv4(nfs_show_stats)

> bm0：attribute_bitmask [0],支持哪些属性
> bm1：attribute_bitmask [1],支持哪些属性
> acl：acl_bitmask,支持哪些acl属性

sec,此安装有效的安全风格(nfs_show_stats)

> flavor：auth-> au_ops-> au_flavor
> pseudoflavor：auth-> au_flavor

xprt(tcp)

> linux / net / sunrpc / xprtsock.c：xs_tcp_print_stats
> linux / include / linux / sunrpc / xprt.h：struct rpc_xprt

> srcport：短暂的端口
> bind_count：rpcbind操作有多少
> connect_count：TCP连接的数量
> connect_time：连接多长时间
> idle_time：传输空闲多长时间
> rpcsends：多少套接字发送
> rpcrecvs：接收多少个套接字
> badxids：已收到多少个无法匹配的XID
> req_u：线路上的平均请求(槽表利用率)
> bklog_u：积压队列利用率(baklog队列的平均长度)
> max_slots：使用max rpc_slots
> sending_u：发送q利用率
> pending_u：pend q利用率

每个RPC操作类型显示(rpc_print_iostats)

统计记录：rpc_exit_task —> xprt_release —> rpc_count_iostats

这里解释了所有NFS协议：http://www.freesoft.org/CIE/Topics/115.htm

> op类型的名称
> ops已请求此类型的操作数
> trans：已发送此op类型的传输次数
>超时：此op类型发生了多少次超时
> bytes_sent：已为此op类型发送了多少字节
> bytes_recv：此op类型已接收到多少字节
> queue：此类型的ops在进入队列之前等待了多长时间
传输(微秒)
> rtt：客户等待接收此操作的回复多长时间
从服务器输入(微秒)
> execute：执行此类型的操作多长时间(来自
rpc_init_task到rpc_exit_task)(微秒)

rpc_run_task —> rpc_new_task —> rpc_init_task

使用ns收集最后三次统计信息,但它们将被转换
打印出来时的ms.

执行时间应接近(队列rtt).

注意,在Linux源代码中,字段的名称以前缀为前缀
例如,“om_”,第一个字段是“om_ops”而不是“ops”.
