The example plugin prints “example” on every query received. It serves as documentation for writing CoreDNS plugins.
If monitoring is enabled (via the prometheus directive) the following metric is exported:
coredns_example_request_count_total{server} - query count to the example plugin.The server label indicated which server handled the request, see the metrics plugin for details.
This plugin implements dynamic health checking. It will always return healthy though.
In this configuration, we forward all queries to 9.9.9.9 and print “example” whenever we receive a query.
. {
forward . 9.9.9.9
example
}
