There is no volume response data in vplex

zhangdl2

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)

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.

zhangdl2

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.
