DNS performance monitoring in Zabbix

[sojjan1337]

Hello #help!

Can i use Zabbix for mesuring dns performance?


Metrics:
DNS requests The number of DNS requests made from the client.
DNS requests / second The rate of DNS requests made by the client.
DNS response time The average response time of the DNS server to a request from the client.
Timeouts The number of timed out DNS requests from the client (displayed as a percentage of all DNS responses).
Errors The number of requests from the client that generated DNS error codes (displayed as a percentage of all DNS responses).
SERVFAIL The number of requests from the client that generated SERVFAIL (DNS server failed to respond) codes (displayed as a percentage of all DNS responses).
NXDOMAIN The number of requests from the client that generated NXDOMAIN (domain name does not exist) codes (displayed as a percentage of all DNS responses).
OTHER The number of requests from the client that generated error codes that are not NXDOMAIN or SERVFAIL (displayed as a percentage of all DNS responses).
Failures The total number of timeouts and errors in DNS requests from the client (displayed as a percentage of all DNS responses).

Zabbix is extensible, so for anything that isn't "built in" to Zabbix, if you can figure out how to gather a data point using a command or script, you can make Zabbix collect and alert upon that data. The difficult part is often figuring out how to gather a particular metric.

If you search around you may find people have posted templates or other examples of how they are choosing to monitor DNS in their environment. They may be useful to you.

These last few lines look like marketing bullet-points for some other product.
