-<h3><a id="topic30"></a>Searching the HAWQ Server Log Files</h3>
-
-<p>You can use the <code>gplogfilter</code> HAWQ utility to search through
a HAWQ log file for entries matching specific criteria. By default, this utility searches
through the HAWQ master log file in the default logging location. For example, to display
the entries to the master log file starting after 2 pm on a certain date:</p>
-<pre class="highlight shell"><code><span class="gp">$ </span>gplogfilter
-b <span class="s1">'2016-01-18 14:00'</span>
-</code></pre>
-
-<p>To search through all segment log files simultaneously, run <code>gplogfilter</code>
through the <code>hawq ssh</code> utility. For example, specify a &lt;seg_hosts&gt;
file that includes all segment hosts of interest, then invoke <code>gplogfilter</code>
to display the last three lines of each segment log file on each segment host. (Note: enter
the commands after the <code>=&gt;</code> prompt, do not include the <code>=&gt;</code>.):</p>
-<pre class="highlight shell"><code><span class="gp">$ </span>hawq
ssh -f &lt;seg_hosts&gt;
-<span class="gp">=&gt; </span><span class="nb">source</span>
