.SH "NAME"
trace-cmd-agent \- Run as an agent on a machine (to be controlled by another machine)
.SH "SYNOPSIS"
.sp
\fBtrace\-cmd agent\fR [\fIOPTIONS\fR]
.SH "DESCRIPTION"
.sp
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\&.
.SH "OPTIONS"
.PP
\fB\-N\fR \fIclient\fR
.RS 4
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\&.
.sp
.if n \{\
.RS 4
.\}
.nf
*This is a very insecure setting\&. Only use on a trusted network*
*Only use if the client machine is totally trusted*

\fB\-p\fR \fIport\fR
.RS 4
This option will specify the port to listen to\&.

\fB\-D\fR
.RS 4
This options causes trace\-cmd agent to go into a daemon mode and run in the background\&.
.RE
.PP
\fB\-P\fR \fIcid\fR
.RS 4
Allow an agent to also act as a proxy server, where it can be run on a host and connect with a guest\&.
\fIcid\fR
is the context ID (see
\fBvsock\fR(7)) of the client (e\&.g\&., guest VM) it will allow to connect\&.
.RE
.PP
\fB\-\-verbose\fR[=\fIlevel\fR]
.RS 4
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\&.

Example: enable all critical, error and warning logs
