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? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
