<p>I want to change kube-apiserver log level use --v parameter , I checked all the documents, and none of them gave the value range of this parameter.</p>
<p>Check the code, the value is int32 type, I tried to fill in 0, 1, 2, and even 9999, all can pass the verification and start kube-apiserver normally.</p>
<p>So I want to know what is the value range of this parameter.Is the value 9999 really meaningful?</p>

<p>9999 isn't a valid value.</p>

<p>I suggest not to increase the verbosity of the logs in the production environment (activate them only if necessary, otherwise you may have performance problems).</p>
