ANY IDEAS HOW RESOLVE THIS?

thanks in advance

Might want to search the internet for python, pip and the error message.
This isn't a nagios issue.

Needed to reinstall nagioxi to move from centos 7 to centos 9
Fresh install of the nagioxi ova virtual machine.
Restored the backup of the centos 7 version of nagiosxi. Could not install pyvmomi per your post

My fix/workaround was to install pyvmomi using yum.
yum install python3-pyvmomi
version 7.0.3 was installed

[root@localhost pip]# yum info python-pyvmomi

All of my vmware checks worked after updating the plug-ins using this document

Hello @rcoxe,

Glad to hear you found a successful work-around. Since you found a solution, I will lock this thread.

I'm going to reopen this thread, only because @rcoxe was not the original poster.

@jorgeaaq, did the fix that worked for @rcoxe work for you? Seems like a good solution.

Hi

I found the solution for rcoxe viable but, that option give me a very old version of the module pyvmomi, but is the only RPM version provided and is ok

Now, I post the question here because, I follow the commands that nagios xi web interface show as prerequisites and expect some kind of testing from nagios xi before post the commands in the interface

Now, my solution to make work the guide and commands of nagios xi web was:


I found that there is a problem was the version of setuptools

when the setup of pyvmovi calls setup.py

"pyvmomi_eb551e3266b44268b27be8d1df5a64d9/setup.py"

the setuptools version 72.1 returns two values from /setuptools/_core_metadata.py

"canonicalize_version(version, strip_trailing_zero=False)"

and the pyvmovi setup.py only expect 1 value "version" and not expect "strip_trailing_zero=False"

I am checking on some sites and found that some changes in setuptools above 70 have some incompatibilities with several projects

I just change the function canonicalize_version to return one value, "version" and remove the second

"canonicalize_version(version)"

after that, the installation works and the app is working

obviously, this is only works in this case... I am going to put a request in the site of the project pyvmovi with this incompatibility with setuptools above 70 so they can develop a more comprehensive and complete solution

for the moment with versions

pyvmomi-8.0.3.0.1 with setuptools-72.1.0

this change make the installation possible

Note: I return the original line of two values in _core_metadata.py because the 2 values could be expected on other apps

jorgeaaq,

Good, I'm glad to hear you found a solution, and thank you for the write up; it may help others in the future.

Just to be absolutely clear - did you have to do anything on the Nagios XI side? If there is something we can improve, I'd like to do so.

Best Regards,

Cory Norell

in strict sense , there is nothing wrong in nagiosxi ...

but maybe, as long as the problem in the pyvmomi module is not corrected with the new version of setuptools, I see three possible solutions

1.- the least recommended, would be to remove the new nagios xi wizard and plugin, as long as the situation is not corrected

2.- another more appropriate option is to change the instructions so that the wizard dependencies are not installed through PIP but with RPM as suggested by rcoxe, they are outdated but functional versions

3.- change the instructions to force pip to install a lower version of setuptools that is compatible with the pyvmomi module... I am not an expert in this but in pip install you can define the specific version of setuptools and in that way the latest version is not installed, but the version that is compatible with the module pyvmomi

I mention this because even though we know that the module is not part of nagios xi, people see the instructions on screen of nagios xi app, when they run the wizard and execute them as mentioned there... and at this moment (August 2024) those instructions do not work and do not allow the use of the wizard/plugin

that are my ideas

Jorge Arenas

jorgeaaq,

Thank you for the feedback. I'll open an issue internally to improve the instructions / user experience surrounding pyvmomi and the VMWare plugin/wizard.

Best Regards,

Cory Norell

Thanks for the input. It seems to be an issue where pip isnt finding the package correctly however installing via yum or dnf like mentioned above seems to work. We took your advice and in an up coming release there is additions to the instructions mentioning if pip is failing to install the package via yum or dnf.
