We set up a zabbix-proxy in AWS running on an ec2 instance which is behind a network Load Balancer. The LB has a listener on port 10050, 10051 and 80 and associated target groups pointing to the proxy instance

We have a zabbix role with an iam policy as explained in https://www.zabbix.com/integrations/aws_ec2 and we also installed the 6.0 AWS EC2 by HTTP template on our frontend server

Steps to reproduce:

• add another ec2 instance in same vpc to the frontend server to monitor and associate the template
• ensure the template macros contain the zabbix user access keys and region
• ensure the ec2 instance macro contains the instance id
• check that the agent is sending data to the proxy
• check that the active proxy is sending data to the server

Result:

Expected:
the proxy collects data for the specific instance and sends it to the server

The frontend ui displays latest data for the EC2 instance
