[Xen-users] xentop output

[张伟 <zhangwqh@xxxxxxx>]

Hi all,

On xen platform, the output of xentop tool is like this:

   NAME  STATE   CPU(sec) CPU(%)     MEM(k) MEM(%)  MAXMEM(k) MAXMEM(%) VCPUS NETS NETTX(k) NETRX(k) VBDS   VBD_OO   VBD_RD   VBD_WR  VBD_RSECT  VBD_WSECT SSID

  Domain-0 -----r      96025    0.0    3902464   23.3   no limit       n/a    12    0        0        0    0        0        0        0          0          0    0

    slave3 --b---      85503    0.0    4194304   25.1    4194304      25.1     2    1 306216192 295309657    2        0  2032574 13715707   98292076 1148951840    0

    slave4 --b---        194    0.0    4194304   25.1    4194304      25.1     2    1    13351      618    2        0    19004     9195     477868     146040    0

     

Now I use xentop to get disk bandwidth or usage information. However, I do not know clearly the specific meaning of  these four columns VBD_WR  VBD_RSECT  VBD_WSECT.

Does anybody know what the meaning for these four columns?
