Description of problem

The DNS Operator documentation describes how to configure the log level for CoreDNS but does not tell how to get the logs.

Version-Release number of selected component (if applicable)

4.16 through 4.10. The capability and documentation for customizing the CoreDNS log level were added in OCP 4.10.

How reproducible

100%.

Steps to Reproduce

1. Read <https://docs.openshift.com/container-platform/4.12/networking/dns-operator.html#nw-dns-loglevel_dns-operator> or the corresponding documentation for any of the affected OpenShift releases.

Actual results

The documentation explains how to set the log level, but not how to read the logs.

Expected results

The documentation should explain how to read the logs. For example:

You can view CoreDNS logs by using the `oc logs` command.

[source,terminal]
----
$ oc -n openshift-dns logs -c dns dns-default-s58l9
----

[source,terminal]
----
$ oc -n openshift-dns logs -c dns -l dns.operator.openshift.io/daemonset-dns=default -f --max-log-requests=6 <1>
----
