There is no volume response data in vplex

Hi 
Our vplex firmware version is 5.3.0.03.00.04, and the performance data collect is ok.
but volumes don't have response date.

  • Hi,

    can you check if Vplex provide response time statistics in the monitors for your volumes?

    Downloaded monitors by stor2rrd are stored in this directory: /home/stor2rrd/stor2rrd/data/<storage name>/iostats

    cd /home/stor2rrd/stor2rrd/data/<storage name>/iostats
    cat *VIRTUAL_VOLUMES_PERPETUAL_MONITOR.log | egrep "<volume name>|Virtual Volume,VPD Id,"

    You are looking for these 2 stats: 'fe-lu read-lat recent-average (us)', 'fe-lu write-lat recent-average (us)'
  • There is no response time statistics in monitors
    -bash-4.2$ more director-1-1-A_VIRTUAL_VOLUMES_PERPETUAL_MONITOR.log
    Virtual Volume,fe-lu ops (counts/s),fe-lu read (KB/s),fe-lu write (KB/s),fe-lu read-avglat (us),fe-lu write-avglat (us)
    2018-06-06 17:25:33
    device_CLARiiON0028_LUN_00017_1_vol,0.1,0.05,0,12716,0
    device_CLARiiON0251_LUN_72_1_vol,0.1,0.05,0,11674,0

  • Hi,

    the response time statistics are there, but the names of that statistics are different than we expect.

    response time read = fe-lu read-avglat (us), fe-lu read-lat recent-average (us)
    response time write = fe-lu write-avglat (us), fe-lu write-lat recent-average (us)

    We have sent you a hotfix via email.
    Please let us know if it helped, thanks.
  • it works,thanks very much.
  • Hi,

    thanks for confirmation.
    This fix will be included in the new version 2.31-1 of stor2rrd, which will be released this week.
