Hello everyone,

 

We updated our ESXi to version 8.
So I'm trying to configure the new VSphere8 connector without success.

I created a dedicated account on vCenter for monitoring.
This account is functional since the "host-status" mode is working correctly:

/usr/lib/centreon/plugins/centreon_vmware8_esx_restapi.pl --plugin=apps::vmware::vsphere8::esx::plugin --mode=host-status --hostname='vcenter.mycompany.fr' --port='443' --proto='https' --esx-id='host-1234' --username='supervision-centreon@vsphere.local' --password='XXXXXXXXXXXX' OK: Host 'esx1.mycompany.fr', id: 'host-1234': power state is POWERED_ON, connection state is CONNECTED

I can also connect to vCenter via the web and view the characteristics of my ESXi and VMs.

I'm having a problem with all other services associated with this connector:

/usr/lib/centreon/plugins/centreon_vmware8_esx_restapi.pl --plugin=apps::vmware::vsphere8::esx::plugin --mode=power --hostname='vcenter.mycompany.fr' --port='443' --proto='https' --esx-name='esx1.mycompany.fr' --esx-id='host-1324' --username='supervision-centreon@vsphere.local' --password='XXXXXXXXXXXX'  --warning-usage-watts='' --critical-usage-watts='' UNKNOWN: 401 Unauthorized

Have you also encountered this kind of problem?

Hi,

Maybe a silly question but, just by chance, did you try only specifying “ --esx-id” rather than both “ --esx-id” and “ --esx-name “ ?
