The \fBovs\-appctl\fR program provides a simple way to invoke these
commands. The command to be sent is specified on \fBovs\-appctl\fR's
command line as non-option arguments. \fBovs\-appctl\fR sends the
command and prints the daemon's response on standard output.

.IP \fB%d{\fIformat\fB}\fR
The current date and time in the specified \fIformat\fR, which takes
the same format as the \fItemplate\fR argument to \fBstrftime\fR(3).

The current date and time in the specified \fIformat\fR, which takes
the same format as the \fItemplate\fR argument to \fBstrftime\fR(3).
.IP \fB%N\fR
A serial number for this message within this run of the program, as a
decimal number. The first message a program logs has serial number 1,
the second one has serial number 2, and so on.
.IP \fB%N\fR
A serial number for this message within this run of the program, as a
decimal number. The first message a program logs has serial number 1,
the second one has serial number 2, and so on.
.IP \fB%r\fR
The number of milliseconds elapsed from the start of the application
to the time the message was logged.

.IP \fIwidth\fR
A number specifies the minimum field width. If the escape expands to
fewer characters than \fIwidth\fR then it is padded to fill the field
width. (A field wider than \fIwidth\fR is not truncated to fit.)

The protocol used to speak to Open vSwitch daemons does not contain a
quoting mechanism, so command arguments should not generally contain
white space.
