Monitoring DNS from Zabbix

To monitor the DNS service itself on the port, you can use the following key in the data items (where SERVER is the IP address or DNS server domain):

net.tcp.dns[SERVER]

In order not to create a template from scratch, you can clone eg the standard “Template App SSH Service” by changing the name in it and specifying a new key, the trigger will change automatically. And also in the “Type” we select “Zabbix agent” instead of a simple check.

The next command can be checked from the Linux command line:

zabbix_get -s127.0.0.1 -k'net.tcp.dns[SERVER]'

Naturally, if the answer is 1, the DNS service is started, 0 is not.
