different esx storage latency vSphere and Lpar2rrd

Hi.

How actually storage latency is collected?
All my esxi servers show different latency in vSphere than latency in lpar2rrd->datastores->datastore1->latency

vSphere->srvesx->performance:

vSphere->datastore1->performance

lpar2rr->datastores->datastore1->latency

  • Hi,

    there was a bug, it is already fixed


    Gunzip it and copy to /home/lpar2rrd/lpar2rrd/bin (755, lpar2rrd owner)
    -rwxrwxr-x 1 lpar2rrd lpar2rrd 270538 Oct 12 10:52 bin/vmw2rrd.pl

    If your web browser gunzips it automatically then just rename it: mv vmw2rrd.pl.gz vmw2rrd.pl
    Assure that file size is same as above listed one

    Let it work for couple of hours

  • Thank you for answer, but it didn't help. Even got things worse.

    cluster totals->cpu shows error happened check $LPAR2RRD_HOME$/logs/error-cgi.loglpar2rrd site doesn't show any graphs for datastores

    current version:
    -rwxrwxr-x 1 lpar2rrd lpar2rrd 270538 Nov  1 14:41 vmw2rrd.pl

    old version:
    -rwxrwxr-x 1 lpar2rrd lpar2rrd 262646 Jan 31  2018 vmw2rrd.pl

    attached log->CGI-BIN and log->'Error VMware' :

  • looks like incompatability between this new code and codes in the version you have.
    Upgrade to this version, then it will be ok :)


  • Thank you.
    will try it next week
    let you know results
  • Thank you it works correctly now after applying update. Had troubles after installing it. A lot of graphs stopped showing data don't remember now which exactly. Had to install lpar2rrd-5.09-14 into server from scratch. It's ok, because this is not a product.

    I probably have a similar problem - value of "datastore latency" is very high.

    My system:
    lpar2rrd: 6.00
    vCenter, esxi: 6.5
    vSphere SDK for Perl: 6.5

    esxi latency:


    lpar2rrd latency:



    In log 'error-vmware.log' appars entires:
    --cut--
    Wed Feb 20 18:00:34 2019: total Read/Write Latency_limit peak reached: 12 times for datacenter datastore_datacenter-2 /home/lpar2rrd/lpar2rrd/bin/vmw2rrd.pl:1905
    Wed Feb 20 18:20:33 2019: total Read/Write Latency_limit peak reached: 6 times for datacenter datastore_datacenter-2 /home/lpar2rrd/lpar2rrd/bin/vmw2rrd.pl:1905
    Wed Feb 20 18:40:32 2019: total Read/Write Latency_limit peak reached: 9 times for datacenter datastore_datacenter-2 /home/lpar2rrd/lpar2rrd/bin/vmw2rrd.pl:1905
    --cut--

    On demo page, "datastore latency" also seems to be too high:
