monitor the ESX / ESXi host

[op-team]

Hi,

I'm running NagiosXI 2024R1.3.4 on a RedHat9.5

I have installed the required packages without issue

[root@nagios-01: ~]# pip list | egrep "setuptools|wheel"
setuptools 75.8.0
wheel 0.45.1
[root@nagios-01: ~]# rpm -q python3-pyvmomi
python3-pyvmomi-7.0.3-6.el9.noarch

But running the Vsphere Wizard, i get the error "Required software components are missing"

I'am missing something?
My python version is 3.9.21

Thank for your help

Hi @op-team,

Can you post the output of the following terminal command?

Code: Select all

python3 -m pip show pyvmomi

The wizard is looking for specific output from this command, so this will help with diagnosis. Thanks!

This is the result:

[root@nagios-01: ~]# python3 -m pip show pyvmomi

Any idea?

Hello

I am also experiencing this issue. I installed pyvmomi via pip as well as yum and restarted nagios. NagiosXI version 2026R1.2

You should start a new thread and describe what's going on.

This usually happens when the wizard is checking a different Python environment than the one where pyvmomi is installed.

Even though pip show looks fine, XI often uses its own Python path. Try installing it explicitly with the same interpreter XI uses, for example:

/usr/bin/python3 -m pip install pyvmomi

Then restart Nagios:

systemctl restart nagios

If it still fails, check which python the wizard is calling and make sure pyvmomi is in that exact path. This mismatch is the most common cause of that error.

I agree with @nousgustaoav, pyvmomi is most likely not installed in the place the wizard expects it to be. I recommend trying

Code: Select all

pip3 install --upgrade pyvmomi

as that seems to have the most success.

If that still fails, I recommend opening a support ticket with our Technical Support team at https://support.nagios.com/.
