<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>The trace-cmd(1) agent listens over a vsocket (for virtual machines) or a TCP port
for connections to control the tracing of the machine. The agent will then start
tracing on the local machine and pass the data to the controlling connection.</p></div>

<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
<strong>-N</strong> <em>client</em>
</dt>
<dd>
<p>
    Listen over TCP instead of a vsocket. Must pass in a client host name or IP address
    to allow connection to. It will only connect to the specified client. Note, any process
    on that client can control the agent.
</p>
<div class="literalblock">
<div class="content">
<pre><code>*This is a very insecure setting. Only use on a trusted network*
*Only use if the client machine is totally trusted*</code></pre>

<dt class="hdlist1">
<strong>-p</strong> <em>port</em>
</dt>
<dd>
<p>
    This option will specify the port to listen to.
</p>
</dd>
<dt class="hdlist1">
<strong>-D</strong>
</dt>
<dd>
<p>
    This options causes trace-cmd agent to go into a daemon mode and run in
    the background.
</p>
</dd>
<dt class="hdlist1">
<strong>-P</strong> <em>cid</em>
</dt>
<dd>
<p>
    Allow an agent to also act as a proxy server, where it can be run on a host
    and connect with a guest. <em>cid</em> is the context ID (see <strong>vsock</strong>(7)) of the
    client (e.g., guest VM) it will allow to connect.
</p>
</dd>
<dt class="hdlist1">
<strong>--verbose</strong>[=<em>level</em>]
</dt>
<dd>
<p>
     Set the log level. Supported log levels are "none", "critical", "error", "warning",
     "info", "debug", "all" or their identifiers "0", "1", "2", "3", "4", "5", "6". Setting the log
     level to specific value enables all logs from that and all previous levels.
     The level will default to "info" if one is not specified.
