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

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

到目前为止,我的搜索没有带来任何有用的信息。

谢谢你的帮助

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

  • 待定_u:待定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(protocol): http://www.freesoft.org/CIE/Topics/115.htm
  • 操作类型的名称
  • ops 请求了多少此类操作
  • trans:发送了多少次这种操作类型的传输
  • timeouts:发生了多少次此操作类型的超时
  • bytes_sent:为此操作类型发送了多少字节
  • bytes_recv:此操作类型已接收多少字节
  • 队列:这种类型的操作在队列中等待了多长时间
    传输(毫秒)
  • rtt:客户端等待接收此操作的回复的时间
    从服务器输入(毫秒)
  • 执行:执行这种类型的操作需要多长时间(从
    rpc_init_task 到 rpc_exit_task)(毫秒)

  • rpc_run_task ---> rpc_new_task ---> rpc_init_task
    使用 ns 收集最后三个时间统计信息,但它们被转换
    到 ms 打印出来时。
    执行时间应该近似于 (queue + rtt)。
    请注意,在 Linux 源代码中,字段的名称以
    “om_”,例如第一个字段是“om_ops”而不是“ops”。
