<span id="sec-tutorial-help-documentation"></span><h3>HTML documentation<a class="headerlink" href="#html-documentation" title="Permalink to this headline"></a></h3>
<p>Most modules have HTML documentation. When installed, it can be found in <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>
under <em>Docs</em>. The HTML documentation can also be reached from the <em>Help</em> menu of all GUIs.
It contains the description of configuration and command-line parameters along with
an overview with many detailed information.</p>
<div class="figure align-center" id="id5">

</div>
<p>The description of most configuration parameters is also available from
within <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>.
Look under <em>Modules</em>, and choose the relevant module.
For each parameter, the first few lines of description are shown;
hovering over these reveals the full text.</p>
<p>The HTML documentation is built regularly and available online, e.g.
<a class="reference external" href="https://docs.gempa.de">gempa’s documentation</a>.</p>

<span id="sec-tutorial-help-commandline"></span><h3>Commandline help<a class="headerlink" href="#commandline-help" title="Permalink to this headline"></a></h3>
<p>In addition to the HTML documentation, many SeisComP commands have manual
pages which can be read on the command line:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$ man <span class="o">[</span>module name<span class="o">]</span>

</pre></div>
</div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The command-line option <em>-h</em> can be used with almost all modules. No matter how many
other command-line parameters were given, <em>-h</em> will stop the module and print
the help on the command-line.</p>

<div class="section" id="logging">
<span id="sec-tutorial-help-logging"></span><h3>Logging<a class="headerlink" href="#logging" title="Permalink to this headline"></a></h3>
<p>Most SeisComP applications use a standard logging approach.
By default, they log to files in your <code class="file docutils literal notranslate"><span class="pre">~/.seiscomp/log</span></code> directory,
such as <code class="file docutils literal notranslate"><span class="pre">scamp.log</span></code>.
Further options for logging are described in
<a class="reference internal" href="../concepts/configuration.html#concepts-configuration"><span class="std std-ref">Configuration</span></a>.</p>
<p>You can control how often these are rotated
(old log files are closed, and moved to a new file name, such as scamp.log.1, e.g. daily).
Alternatively you can use the system-wide logging facility <cite>syslog</cite>
and send logs to /var/log or another “standard” place.</p>
<p>There are four levels of severity of SeisComP log messages,
and applications can be configured to show only those which
are more severe than a given threshold.</p>
<ul class="simple">
<li><p>1 = ERROR</p></li>
<li><p>2 = WARNING</p></li>
<li><p>3 = INFO</p></li>
<li><p>4 = DEBUG.</p></li>
</ul>
<p>Default is 2.
Setting <cite>logging.level = 4</cite> results in the most messages.</p>
<p>For other modules such as <a class="reference internal" href="../../apps/seedlink.html#seedlink"><span class="std std-ref">seedlink</span></a>, the log files are written to
<code class="file docutils literal notranslate"><span class="pre">seiscomp/var/log/</span></code></p>
</div>
<div class="section" id="debugging-options">
<span id="sec-tutorial-help-debugging"></span><h3>Debugging options<a class="headerlink" href="#debugging-options" title="Permalink to this headline"></a></h3>
<p>Most SeisComP applications support two important command line options:</p>
<ul class="simple">
<li><p>Use <cite>–console</cite> to send output to the terminal instead of the usual
log location.</p></li>
<li><p><cite>-v</cite> for increased verbosity, or use <cite>–verbosity=</cite> <em>n</em> where <em>n</em>
is one of the four severity levels above.</p></li>
</ul>
<p>In addition:</p>
<ul>
<li><p><cite>–debug</cite> sets logging.level (see above) to 4 (DEBUG),
and sends logging output to the console (terminal) instead of the usual
log location.
(This is just an easier way of specifying <cite>–verbosity=4 –console=1</cite>.)
For example:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$ ~/seiscomp/bin/seiscomp <span class="nb">exec</span> scmag --debug
<span class="m">11</span>:47:50 <span class="o">[</span>debug<span class="o">]</span> Adding plugin path: .

</pre></div>
</div>
<p>The above reveals that <strong class="program">scmag</strong> was able to load, and connect to the
messaging system.
Note that the <em>verbosity</em> of each message (“info”, “debug”, etc) is also
shown.
However a moment later we see:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="m">11</span>:47:51 <span class="o">[</span>info<span class="o">]</span> Connect to database
<span class="m">11</span>:47:51 <span class="o">[</span>debug<span class="o">]</span> skipping unknown network message

</pre></div>
</div>
<p>This suggests that <a class="reference internal" href="../../apps/scmaster.html#scmaster"><span class="std std-ref">scmaster</span></a> was not running to provide a
connection to the database.
To resolve this, you could next check that <a class="reference internal" href="../../apps/scmaster.html#scmaster"><span class="std std-ref">scmaster</span></a> is
running as expected.</p>
</li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Instead of <cite>–debug</cite> in the example above, you could run</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$ ~/seiscomp/bin/seiscomp <span class="nb">exec</span> scmag -vvvv
</pre></div>
</div>
<p>The output is the same, but it is sent to your normal logging file,
typically <cite>~/.seiscomp/log/scmag.log</cite>.</p>
</div>
<p>In <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>, logging can be set globally.
Go to the Modules tab, then System &gt; global (see “logging”)
or per module.</p>
<p>e.g. set “logging.level = 3” in $SEISCOMP_ROOT/etc/scamp.log
to set level to <em>INFO</em> only for <a class="reference internal" href="../../apps/scamp.html#scamp"><span class="std std-ref">scamp</span></a>.</p>
<p>You should also be aware of the version of SeisComP that you are running.
The ‘-V’ or ‘–version’ option provides this for many SeisComP modules.</p>
