Hello, 

I'm not able to reproduce exactly your issue but if you try to create the json file manually with good rights on the poller  : 

touch /etc/centreon/centreon_vmware.json
chown centreon-gorgone:centreon /etc/centreon/centreon_vmware.json
chmod 644 /etc/centreon/centreon_vmware.json

After that, are you able to correctly install the daemon ? 

Once the daemon is installed, could you try to check /var/log/centreon-gorgone/gorgoned.log file on the poller while exporting the configuration
If you have some right issues, you should see messages like this : 

2025-04-02 09:06:29 - ERROR - Oaction] Copy processing - Can't copy file to /etc/centreon/centreon_vmware.json, Permission denied
2025-04-02 09:06:30 - ERROR - Oaction] Copy processing - MD5 does not match

Hope it helps ! 

Hello,

Thank you, as of now, I have exactly the messages like you mentionned.

I was able to create and to add the right on the json file :

root@poller1:~# touch /etc/centreon/centreon_vmware.json
root@poller1:~# chown centreon-gorgone:centreon /etc/centreon/centreon_vmware.json
root@poller1:~# chmod 644 /etc/centreon/centreon_vmware.json

Then, after I export the configuration ( the GUI now warns me that 

but when I use the “legacy export, there are is error at all.

And when looking at the “/var/log/centreon-gorgone/gorgoned.log”

Hello again, 

Did you manage to update the daemon after creating the file ? 
Could you please provide the version installed with the following command, in my case, I have this version : 

root@centreon-poller-0:~# apt list --installed | grep centreon-plugin-virtualization-vmware-daemon
centreon-plugin-virtualization-vmware-daemon/bookworm,now 3.4.0-1+deb12u1 all ainstalled]

If your version is lower, could you try updating the daemon first? 

After that, the errors of centreon_vmware service raises several problems : 

1.

Apr 02 14:16:05 poller1 perlr649439]: Cannot open file /var/log/centreon_vmware.log: Permission denied

• There seems to be a problem with the rights to the log file, here are the rights on my side :

Could you provide the content of the following files :
/lib/systemd/system/centreon_vmware.service : 

uUnit]

# cat /etc/default/centreon_vmware
# centreon_vmware command line options
OPTIONS="--config-extra=/etc/centreon/centreon_vmware.json --logfile=/var/log/centreon/centreon_vmware.log --severity=info"

We had an issue where the /lib/systemd/system/centreon_vmware.service file doesn't use the environment file this could explain the behaviour observed 

For an advanced debug of the problem of deploying configuration files, you would have to put gorgone in debug mode on the poller and the central, by modifying the /etc/default/gorgoned file by changing the ‘severity’ option to debug and then restarting the gorgoned service.

Hello,

Thank you for trying to help us .

We have the same version as yours.

And 

/etc/default/centreon_vmware

Could it be related to the upgrade we did, from Debian 11 to Debian 12 ? It seems strange that all of the files on the “/var/log/centreon/” folder does not have a proper owner.

Regards,

Hello, 

I don't know if the rights problem can be linked to the upgrade from Debian 11 to Debian 12 but there is clearly a problem there.
The first step would be to restore rights for folders/files with non-existent UIDs as owners, which could correct the rights issue when copying configuration files.

Regarding the configuration of the centreon_vmware service, could you modify the /etc/default/centreon_vmware file so that it matches the one sent in my previous message.
Once this has been done, you will need to restart the centreon_vmware service.
This will allow the daemon to use the new configuration file format

Regards

Hello,

I did change the right on the folder :

/var/log/centreon/

root@poller1:~# ls -l /var/log/centreon/

-rw-r--r-- 1 centreon centreon        0 Jun 12  2024 centreontrapd.log

-rw-r--r-- 1 root     root     19507977 Apr  4 15:00 ORIGINAL_centreon_vmware.log

I also copied then remove the original centreon_vmware.log file, to see if the service is able to create a new one. It seems it is, with the correct rights, but the file is empty.

And this is the result relaunching the service :

root@poller1:~# systemctl status centreon_vmware

I also changed the centreon_vmware file, as requested :

root@poller1:~# cat /etc/default/centreon_vmware
# centreon_vmware command line options

OPTIONS="--config-extra=/etc/centreon/centreon_vmware.json --logfile=/var/log/centreon/centreon_vmware.log --severity=info"

What it strange right there, if that we specifiy the severity to “info” but there is no log at all.

Regards,

Hello,

It's a very strange behaviour, I've never encountered this problem.
Do you still have this problem? 
Is it possible that you still have files that don't have a real user as owner, like for the log files? (only uid /gid)

find / -nouser

Is the /etc/centreon/centreon_vmware.json file now correctly deployed?

find / -nouser

Hello,

Here is the ouput of the 

find / -nouser

root@poller1:~# find / -nouser
find: ‘/proc/3321096/task/3321096/fd/6’: No such file or directory
find: ‘/proc/3321096/task/3321096/fdinfo/6’: No such file or directory
find: ‘/proc/3321096/fd/5’: No such file or directory

/etc/centreon
/etc/centreon/.centreon_vmware.pm.swp
/etc/centreon/centreontrapd.pm
/etc/snmp/centreon_traps

If you can confirm me that the correct owner of the last four files is “centreon”, I’ll make the changes.

Yes, the following file exist

/etc/centreon/centreon_vmware.json
