Problem with retrieving data from vCenter: SOAP request error

piterko

Hi, 
I just started my journey with lpar2rrd and after successful plug of power environment I would like to plug VMware part. End then problems began. 
From the prerequisites I hope I made all needed things. I tried with several Perl-SDK starting with 6.0, then 6.5 and 6.7. Each time, during load.sh script execution I'm getting such error: 

SOAP request error - possibly a protocol issue: <?xml version="1.0" encoding="UTF-8"?>

<soapenv:Envelope xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

 xmlns:xsd="http://www.w3.org/2001/XMLSchema"

 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

and after that long list with Intel processors, and "For more information, see Knowledge Base article 1003212" which is about vMotion
before the SOAP part I have: 

heatmap        : (VMware) set cpu utilization for 0 vm

heatmap        : (VMware) set memory utilization for 0 vm

heatmap        : (VMware) set cpu utilization for 0 pools

heatmap        : (VMware) set memory utilization for 0 pools

An error occured in lpar2rrd, check /var/www/lpar2rrd/logs/error.log-vmware and output of load.sh

A few words about my environment: 
lpar2rrd server: AIX 
lpar2rrd version: 6.02
VMware perl SDK: 6.7
vCenter version: 6.0

$PERL vmware-lib/apps/connect.pl --version

vSphere SDK for Perl version: 6.7.0

Script 'connect.pl' version: 1.0

perl -MLWP -e 'print "$LWP::VERSION\n"';

6.06

perl -MNet::HTTP -e 'print "$Net::HTTP::VERSION\n"'

6.06
Installed Perl rpms: 

perl-5.8.8-2.ppc

perl-Crypt-SSLeay-0.57-2.ppc

perl-TimeDate-1.20-1.noarch

perl-XML-Parser-2.41-1.ppc

perl-XML-NamespaceSupport-1.11-1.noarch

rrdtool-perl-1.4.8-2.ppc

perl-Compress-Raw-Zlib-2.020-1.ppc

and as I found similar topic, for me didn't help restart of vCenter and ESX hosts I can't touch. 

Any idea where problem can be?

Hi,

it all looks good, basically here is our troubleshooting manual.

what reports this:

. etc./lpar2rrd.cfg

$PERL -MLWP -e 'print "$LWP::VERSION\n"';

echo "$PERL $PERL5LIB"

For your first post:

$PERL -MLWP -e 'print "$LWP::VERSION\n"';

6.06

echo "$PERL $PERL5LIB"

1. rpm -qa | egrep -i "Crypt-SSLeay|Net_SSLeay"

perl-Crypt-SSLeay-0.57-2.ppc

2. for PERL5LIB I used those from tutorial for lpar2rrd installation and add some which were missing when I install it (output above) 
3. for vmware-lib they were included in PERL5LIB
4. $PERL -MLWP -e 'use LWP::Protocol::https; print "LWP Version: $LWP::VERSION\n"'

LWP Version: 6.06
5. $PERL bin/perl_modules_check.pl returns nothing 
6. $PERL vmware-lib/apps/connect.pl --server --username "lpar2rrd@your_domain" --password "XXXXX"
getting:

Hi,

it says conmnection succesfull, it looks good, do you see anything in the GUI after Ctrl-F5

piterko

Hi, 
unfortunately no. Nothing new in GUI even after change web browser, refresh cache and so one. Moreover I don't see anything in data and tmp dirs (all permissions are set properly to allow writing for lpar2rrd and read by server www). 

piterko

I made one another test with vmware loop test: 

$PERL bin/vmware_loop_test.pl --server <<server>> --username "lpar2rrd@<<my_domain>>" --password "<<PASSWORD>>"

Hi,

sorry for delay.

1. use rather Perl SDK 6.5, not 6.7 one if you have older vCenter

before its installation clean actual vmware-lib directory

cd /home/lpar2rrd/lpar2rrd

rm -r vmware-lib/*

install 6.5 SDK as per docu

2. use PERL5LIB mentioned in this codu: https://www.lpar2rrd.com/https.htm

change path if necessary (/home/lpar2rrd --> /var/www/lpar2rrd)

vmware-lib must be at the second possition!

It must work now

piterko

Hi, 
a bit later answer, but it helped. Probably placing the path to vmware-lib on the second position made the job  
Thank you for help
