There are a couple of ways to do this, but the easiest way in Zabbix is to create an item of type simple check that uses the tcp,port construct. In this case: <HIOSTNAME>,23 This will return a zero if the service fails to connect, or a 1 if it connects.

Hi used net.tcp.listen[23] ,
but it answer :

Simple check [net.tcp.service[net.tcp.listen[23],83.217.25.123]] is not supported

why?

Add a new item
