Currently, the "Azure" template(s) https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/cloud/azure_http?at=refs%2Fheads%2Frelease%2F6.0 do not support specifying HTTP proxy out from box.

Other cloud monitoring templates like AWS do provide this option:

https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/cloud/AWS/aws_http?at=refs%2Fheads%2Frelease%2F6.0

AWS solution allows to define "{$AWS.PROXY}" at template/host level. Azure template(s) does not have a support yet implemented.

Is it possible to implement it and the mainstream solution officially?

With my knowledge, we accomplished some sort of success by locating the line:

.. request = new HttpRequest(); 

and immediately after this line, insert a snippet:

                        if (Azure.params.proxy) {
                            request.setProxy(Azure.params.proxy);
                        } 

There are a lot of items to edit and the question "Is this the most standardized JavaScript way to do it?"

I think this patch must be implemented for templates:

• Azure by HTTP
• Azure Cosmos DB for MongoDB by HTTP
• Azure Microsoft SQL Database by HTTP
• Azure Microsoft SQL Serverless Database by HTTP
• Azure MySQL Flexible Server by HTTP
• Azure MySQL Single Server by HTTP
• Azure PostgreSQL Flexible Server by HTTP
• Azure PostgreSQL Single Server by HTTP
• Azure Virtual Machine by HTTP
