- <h1>Log Files</h1>
- <p>GoAhead provides detailed logging regarding client accesses and the operation of GoAhead.
- The log records the essential GoAhead configuration, details of denied requests, and other trace
- and error information. The log can also record request and response headers and other request details.</p>

- <a name="sample"></a>
- <h2>Sample Output</h2>
- <p>Here is some sample log output.</p>
- <pre class="ui code segment">
- goahead: 2: Configuration for Embedthis GoAhead
- goahead: 2: ---------------------------------------------
- goahead: 2: Version: 3.0.0-0
- goahead: 2: BuildType: Debug
- goahead: 2: CPU: x64
- goahead: 2: OS: macosx
- goahead: 2: Host: 10.0.0.102
- goahead: 2: Directory: /Users/mob/git/goahead
- goahead: 2: Configure: me configure
- goahead: 2: ---------------------------------------------
- goahead: 2: Started http://*:80
- goahead: 2: Started https://*:443
- </pre>
- <p>Each line in the error log is prefixed with source information. This follows the format:</p>
- <pre class="ui code segment">
- program:logLevel
- </pre>
- <p>The log level is the verbosity level assigned to the trace information by GoAhead.</p>
- <a name="logs"></a>
- <h2>Log Files</h2>
- <p>The default location of the log file is specified at build time via the command:
- <pre class="ui code segment">./configure --set trace="file:level"</pre>
- <p>The log filename can be set to "stdout" or "stderr". The debug level specifies the desired trace verbosity.
- Level 0 is the least verbose and level 9 is the most verbose.</p>
- <p>Configure will defines a <em>ME_TRACE</em> definition in the <em>me.h</em> configuration header that is used
- to set the default log location. After building, the trace can be redirected via a <em>goahead</em> command line option.
- <h3>Command Line Log Option</h3>
- <p>You may specify the error log file and log level via the GoAhead command line <em>--log</em> option. If you
- invoke GoAhead with a <em>--log file:level</em>. command line option, it will override the build time
- defaults.</p>
