Nagios not showing correct Datastore size

[bosecorp]

Team,

When I run the below command to check the data store capacity I am getting the below output
# /usr/local/nagios/libexec/check_esx3.pl -H "10.101.28.24" -f "/usr/local/nagiosxi/etc/components/vmware/usmadcevm04_bose_com_auth.txt" -l "VMFS" -s dce-Paging_2 -c99.90% -w99%
ESX3 CRITICAL - dce-Paging_2=2095915.00 MB (99.95%) | dce-Paging_2=99.95%;99;99.9
# /usr/local/nagios/libexec/check_esx3.pl -H "10.101.28.24" -f "/usr/local/nagiosxi/etc/components/vmware/usmadcevm04_bose_com_auth.txt" -l "VMFS" -s dce-Paging_1 -c99.90% -w99%
ESX3 OK - dce-Paging_1=218141.00 MB (10.40%) | dce-Paging_1=10.40%;99;99.9

When I go tot Nagios GUI it is showing me the screen as attached and when I check the datastore in VMware it is showing me different value as attached in the file.
e.g. when I try to convert the dce-Paging_1 free space 218141.00 MB to GB it is showing me as 218 GB, but in VMware it is showing me free space as 207 GB (screenshot in the attached file)

We are running Nagios XI.

Is your question dce-paging_2 or dce-paging_1?

What version of the SDK is installed on XI and what VMware version are you connecting too?

This may simply be something like the VMware front-end is calculating space slightly differently.

[bosecorp]

It is not just for dce-paging_2 or dce-paging_1 but for rest of other drives as well.

How to find the SDK version installed on Nagios.

VMware version is ESXi 5.1.

[dwhitfield]

Running find / -name *vmware* should find it for you.

If you find nothing with that, you can try find / -name *VMware*, but the extracted files should be lower case.

I am not able to find the SDK version for VMware.
When I tried to find the SDK version for vmware using "find / -name *vmware* " I am getting the output for all the file names.

Can you please let me know how to find the SDK version for VMware.

/ubstmp/Emmanuel/NagiosXI/vmware-Perl-SDK/VMware-vSphere-Perl-SDK-6.0.0-2503617.i386.tar.gz

Looks like 6.0.0 is downloaded.

I wonder if you'd have better luck using https://exchange.nagios.org/directory/P ... re/details

You could also try updating the version of the plugin you are using.

[bosecorp]

Does this mean that there is an issue with the existing Plug-in that we are using.

[avandemore]

The plugin makes use of the the SDK. For best results, you should have the SDK match the VMWare version you are connecting too.

Ultimately though the data you're comparing is almost an apples to oranges situation. We don't know how VMWare calculates their data. Different things can impact this eg 1000 vs 1024 space calculations, reservations, etc.

Do you have any reason to suspect the Nagios plugin is reporting inaccurate data other than the difference a separately reporting tool is giving?

[bosecorp]

I tried installing perl-Nagios-Plugin-0.35-2.el6.rf.noarch and then when I try to run the ./check_esx3-0.5.pl it gives me the below error message.

root@nagmonusdev1:(02-02 11:43): /tmp
# ./check_esx3-0.5.pl
/usr/bin/perl: symbol lookup error: /usr/local/lib64/perl5/auto/XML/LibXML/Common/Common.so: undefined symbol: Perl_Tstack_sp_ptr

[dwhitfield]

Please run the following

Code: Select all

yum clean all
yum erase perl-XML-SAX-Base-1.04-1.el6.rf.noarch
yum install perl-XML-SAX -y
yum install perl-Nagios-Plugin libuuid* perl-XML-LibXML -y

If the erase command doesn't work, I wouldn't worry about it. Please post any new errors (or if you have the same error)
