Error in connection between host and zabbix

[AviPairupuni]

Hi,

I'm trying to setup this monitoring on our POC zabbix 4.2. I'm having following error while running it manually. Can you please help.

You have timeout - check connection between zabbix host and xenserver. Ping it and check xenserver. czw., 2 sty 2020, 13:50 użytkownik Avinasha <notifications@github.com> napisał:

Thank you very much for your response.

I can ping it, nmap to the xen via 80 and 443 works just fine. but the error remains!!

I'm using a Read Only user for monitoring purpose. Is that level of permission is enough?

Here are the results of wget with https and without "s".

[root@dserver ~]pip show XenAPI
You are using pip version 6.0.8, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Name: XenAPI
Version: 2.14
Location: /usr/local/lib/python3.4/site-packages
Requires: six
[root@dserver ~]# python -V
Python 3.4.3
[root@dserver ~]#

I have updated the above path in the script and did no other changes.

@Danone89 Can you please let me know what level of access does the Citrix User needs to get this monitoring work?

[Danone89]

You need to grant read all, and api access permissions (so pool operator should be fine, but I'm running it on read only). Basically if you grant lower levels you will get false alarms and/or autodiscovery won't find all vm's. My workaround was - start as pool operator (AD will find all what it needs), then switch user to read-only. But in your case I thinking about certificates, in my enviroment we have trusted certs on both ends ( added our CA to trusted).

Thank you for your response @Danone89 . I updated the self signed certificate from the Xen server into Zabbix server(There was already an inter-domain trust earlier). Now that the wget works fine even for https, but the script if run manually, still throwing same error.
