I have a series of IoT devices that I would like to monitor with Zabbix that can not run the Zabbix agent. To monitor the devices I would like to have a server send a web request to these devices and get the response, however these devices work by sending both a synchronous response to the requesting server as well as an asynchronous response to a provided URL which contains the actual data that was requested. We know of someone else that is using Nagios that is able to set up their monitoring server in order to receive these asynchronous response and act accordingly. We would like to know if there is a way to set up Zabbix to do something similar. The alternative would be a rather lengthy process involving writing a daemon and reports data to the Zabbix agent on the Zabbix server, which is quite undesirable. Any assistance would be greatly appreciated!
