Could you check access using the following request from Zabbix server / proxy side:

curl -vv --cookie-jar cookies.txt -X POST -k -v --header "Accept: application/json" -u "login:password" 'https://<server>:9398/api/sessionMngr'

then

curl -vv --location --header 'X-RestSvcSessionId: <token from previous response>' --request GET 'https://hostt:9398/api/backupFiles'

and

curl -vv --location -b cookies.txt --request GET 'https://hostt:9398/api/backupFiles'
Comment by Mike Ely [ 2023 Sep 14 ]

Sorry, this issue fell off my task list. I'm unable to get past the initial auth step to get a session ID:

curl -vv --cookie-jar cookies.txt -X POST -k -v --header "Accept: application/json" -u "HOSTNAME\zabbixuser" 'https://hostname.example:9398/api/sessionMngr'
Enter host password for user 'HOSTNAME\zabbixuser':
*   Trying [hostip]:9398...
* Connected to hostname.example ([hostip]) port 9398 (#0)
...ssl stuff elided, nothing there seems amiss...

Once I add --header "Content-Length: 0" to the login request I do get a SessionId value, but trying to use it fails (piped output to jq for readability):

{
  "FirstChanceExceptionMessage": null,
  "StackTrace": null,
  "Message": "Identity was not authenticated.",
  "StatusCode": 401,
  "Status": "Unauthorized"
}

Hello, 

I have commented the line  in get metrics script and it's solved.

// espace réservé du code
getMetricsData: function() {
        var data = {};
        endpoints = {
            //'backupFiles': 'api/backupFiles',
        };

When i use the web api, i can't connect to the backupFiles. 

It's related to veeam BR ?

Hello,

I have an answer from Veeam Support. You must have Enterprise Plus licence to have an entire functional RestAPI.

Best regards

Comment by Alexey Pustovalov [ 2023 Nov 17 ]

Yes, we have documented such behaviour: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/veeam/enterprise_manager_http/README.md

Comment by Leandro Monasterio [ 2023 Dec 07 ]

Hello! I have this problem with Veeam Backup Enterprise Manager Template:

{"error":"Error: cannot get URL: Timeout was reached."}

I can access the Manager Console, so that is working fine...

Can yo help me please?

I'm having the same problem as leandromonasterio and I'm also using Zabbix 6.0 with Veeam Backup Enterprise Manager 12. I also have a Veeam Enterprise Plus license and I still receive the same error message as Leandro.
