Failed to add vCenter 6.5

Hi all
I have a problem adding a vCenter server via the Configuration Wizard in Nagios XI. I can add a individual ESX host and see the guest running on them OK but adding the vCenter server i get the following error.
Error
It appears there are no guests for this VMware host. The error message is below. This may be because the SDK is not installed, your credentials are wrong, or the host is not a VMware server.
Can't call method "alternateGuestName" on an undefined value at /usr/local/nagiosxi/html/includes/configwizards/vmware/scripts/getguests.pl line 160.
the SDK has been installed and it works. if i deliberately use a wrong username and password i get the following error.
Error
It appears there are no guests for this VMware host. The error message is below. This may be because the SDK is not installed, your credentials are wrong, or the host is not a VMware server.
Error: Cannot complete login due to an incorrect user name or password.
i have 5 ESX 6.5 hosts with 1 vCenter Server Appliance.
any help will be great.
Thanks
Darran

Does the vCenter account you are using have access to all the hosts/guests on the system?

Thanks for the fast reply Scott.
I am using the
[email protected] account to log into vCenter
i use root to log into the individual ESX hosts.
yes i can see the Cluster and the 5 hosts with all the VMs if i use the
[email protected]
sorry for the delay in responding as i have been on holidays.

After further investigation i have found out that the ESX host 5 has the same error message when using the root username.
this may be why the vcenter fails

Let's use the VMWare Perl SDK to see if you can connect to the VMWare servers and bypass using the plugin all together.
Login to the Nagios server as root when running the scripts. Post the output so we can view it.
Change to the following directory
Code: Select all
cd /usr/lib/vmware-vcli/apps/general
Run this to test to see if you can connect to the VMWare VCenter server
Code: Select all
./connect.pl --url https://xxx.xxx.xxx.xxx/sdk/vimService --username <username> --password <password>
If the above passes, go to this directory.
Run this to test to see if you can get the list of hosts connected to the VMWare VCenter server
Code: Select all
./hostinfo.pl --url https://xxx.xxx.xxx.xxx/sdk/vimService --username <username> --password <password>
If the above passes, go to this directory.
Displays the VM Guests running on the system
Code: Select all
./vminfo.pl --url https://xxx.xxx.xxx.xxx/sdk/vimService --username <username> --password <password>
Let us know how it works for you.

I wonder if it is a compatibility issue with that version of the VMWare Perl SDK or that the getguests.pl script cannot find the modules it needs.
Can you login to the Nagios server, run the following and post the output?
Code: Select all
cd /html/includes/configwizards/vmware/scripts/
./getguests.pl -H xxx.xxx.xxx.xxx -u username -p password
Replace xxx.xxx.xxx.xxx with the IP address of the vcenter server.
