unable to monitor vmware 6.7 via MSW

[dlukinski]

I'm referring just to the steps to install the SDK that are covered in the document. The SDK must be installed on the MSW which appears to have failed if you don't' have a vcli.

Alright, Nagios manual is also incorrect:

1. cpan has to be installed before running pre-req commands or they would not run (please update the manual)

2. SDK step would not install because openssl-devel would be missing (please update the manual)

3. After all steps complete successfully, /usr/lib/vmware-cli does NOT exist.

------------------------------------------------------------------------------------------------
NAgios manual steps contradict VMWARE SDK for Perl steps (for CentOS, your stock OS), published in here - https://cyberground.hu/install-vmware-v ... -centos-7/

I've used Centos 7 minimal 2003 image to follow both manuals
-----------------------------------------------------------------------------------------------
Crypt-SSLeay failed to configure / downgrading LWP did not fix it
----------------------------------------------------------------------------------------------
Mixing 2 manuals worked (keep wondering if LWP downgrade did it and if I could re-create this one more time

Are you requesting https://assets.nagios.com/downloads/nag ... ios-XI.pdf be updated because of failures 1, 2, and 3? Just want to be sure as I go to test it again.

When you say 'mixing 2 manuals worked' are you referring to https://cyberground.hu/install-vmware-v ... -centos-7/ and our https://assets.nagios.com/downloads/nag ... ios-XI.pdf ?

Yes i did both manuals and downgraded LWP : got vcli in the end, not sure if operational.

This time vcli was there, but the check did not work:

Code: Select all

[vi-admin@cakc-bur-test02 ~]$  ~/box293_check_vmware.pl --server 172.18.18.19 --check

Is Template.pm found on the machine? It may need to be installed or the script modified to look in the proper locatin. What OS is the MSW?

It is CentOS 7.8 minimal.

I have installed CPAN Text::Template and was able to check the remote vCenter version

Will keep testing and update

I am now getting the same error for all the checks: (Return code of 255 for service 'CPU Info' on host 'cakc-bur-esxi01.finland.tcscloud.com' was out of bounds)

and I am getting "plugin timed out" when trying to check_by_ssh remotely from Nagios to MSW machine

[cdienger]

Is the check that the MSW machine tries to run quick to return? Time it with the following:

Code: Select all

time ./box293_check_vmware.pl --timeoute 90 --server 172.19.1.60 --check Host_CPU_Info --host cakc-bur-esxi01.finland.tcscloud.com --reporting_si CPU_Speed:GHz

Also try just running a simple ls via the check_by_ssh plugin:

Code: Select all

/usr/local/nagios/lib/check_by_ssh -E 1 -t 90 -l vi-admin -H <MSW_IP> -C "ls"

This is the point I got to:

(after entering credentials into the credstore)

Try:

Code: Select all

/usr/bin/vmware-cmd --version
~/box293_check_vmware.pl --server 172.18.18.13 --check vCenter_Name_Version --debug

Provide the output and the /home/vi-admin/box293_check_vmware_debug_log.txt if it is created.

I'd also like to see a packet capture taken at the same time the above command is run:

Code: Select all

tcpdump -s 0 -i any host 172.18.18.13 -w output.pcap

Use CTRL+C to stop the trace after reproducing the problem and send me the output.pcap it creates in a private message.

Hi again

I managed to get the plugin to work, but it keeps asking me for the credentials (even so they were entered successfully):
