Dear Team,

I have installed Zabbix server on my Ubuntu 16.04.4 (32 bit) server and Zabbix agent on Ubuntu 16.04.4 (32 bit) desktop. I would like to monitor multiple TCP ports on my desktop through Zabbbix agent. I have already configured an item with net.tcp.listen[port] and trigger with {Template OS Linux:net.tcp.listen[600].last()}=1 however as I noticed I can monitor only one port at a time. My target is to monitor multiple ports (e.g 500-600,650,651,700-25000). Please guide me how I can configure such item and trigger to fulfill my target.

Many thanks in advance for your time
