different esx storage latency vSphere and Lpar2rrd

Alexey107

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

http://www.lpar2rrd.com/download-static/vmw2rrd.pl.gz

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:

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