What is the default value for logLevel?

Question

I'm using System.Diagnostics on my Azure instances. I have some settings on my webconfig:

<system.diagnostics>
    <switches>
      <!-- Off = 0, Error 1, Warning = 2, Info = 3, Verbose = 4 -->
      <add name="logLevel" value="2" />
    </switches>
    <trace autoflush="true"
     ...

I would like to know what is the default logLevel value.

There is no default value for switch. value is required attribute. Application will throw ConfigurationErrorsException if no value is provided (from here).
