Bug with E590 CPU Total Display


There is a problem with CPU Display on E590 but not with E790

And CPU utilization is not correct on MPU tab for E590

Firmware: 93-06-23/00 (E590 & E790)

Data Collection: REST

Export tool 2 for (E590 & E790)

Stor2rrd version: 7.40

Problem: (Picture 1)

Everything works fine with E790.

What can be the problem: Stor2rrd sees much more CPU on E590 then it has. (Picture 3)


  • Hello,

    Send us logs

    su - stor2rrd (lpar2rrd if you are on the appliance)

    cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir

    tar cvhf logs.tar logs tmp/*txt data/E590/IOSTATS/* data/E790/IOSTATS/*

    gzip -9 logs.tar

    Send us logs.tar.gz via https://upload.stor2rrd.com

    Thank you

  • This might help:

    Hitachi is seeing this CPU:


    From MP10-00 to MP10-11

    From MP20-32 to MP20-43


    From MP10-00 to MP10-31

    From MP20-32 to MP20-63

  • Hello,

    1. I can see bug in E590 -> CPU -> Total -> (Total tab). It should not be an empty graph. Here is the fix:


    Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)

    -rwxr-xr-x 1 stor2rrd stor2rrd 1099921 Jun 10 12:37 storage.pl

    If your web browser gunzips it automatically then just rename it: mv storage.pl.gz storage.pl

    Assure that file size is the same as on above example

    2. About MPU units. Example MPU-10-1C. This "item" does not have cpu utilization but has Write_Pending_Rate and Usage_Rate. From export tool 2

    cat Cache/CLPR/Write_Pending_Rate.csv | grep MPU-10/1C



    cat Cache/CLPR/Usage_Rate.csv | grep MPU-10/1C



    GUI -> STORAGE -> E590 -> CPU -> Items -> MPU-10-1C -> (tabs Write pending and Usage rate)

    Thank you

  • It is working now, thx
