9 Sets logging levels. Without any \fIspec\fR, sets the log level for
10 every module and facility to \fBdbg\fR. Otherwise, \fIspec\fR is a
11 list of words separated by spaces or commas or colons, up to one from
16 A valid module name, as displayed by the \fBvlog/list\fR command on
17 \fBovs\-appctl\fR(8), limits the log level change to the specified
21 \fBsyslog\fR, \fBconsole\fR, or \fBfile\fR, to limit the log level
22 change to only to the system log, to the console, or to a file,

26 useful along with the \fB\-\-syslog\-target\fR option (the word has no
30 \fBoff\fR, \fBemer\fR, \fBerr\fR, \fBwarn\fR, \fBinfo\fR, or
31 \fBdbg\fR, to control the log level. Messages of the given severity
32 or higher will be logged, and messages of lower severity will be
33 filtered out. \fBoff\fR filters out all messages. See
34 \fBovs\-appctl\fR(8) for a definition of each log level.

40 Regardless of the log levels set for \fBfile\fR, logging to a file
41 will not take place unless \fB\-\-log\-file\fR is also specified (see
44 For compatibility with older versions of OVS, \fBany\fR is accepted as
45 a word but has no effect.
48 .IQ "\fB\-\-verbose\fR"
49 Sets the maximum logging verbosity level, equivalent to
50 \fB\-\-verbose=dbg\fR.

56 .IP "\fB\-vPATTERN:\fIfacility\fB:\fIpattern\fR"
57 .IQ "\fB\-\-verbose=PATTERN:\fIfacility\fB:\fIpattern\fR"
58 Sets the log pattern for \fIfacility\fR to \fIpattern\fR. Refer to
59 \fBovs\-appctl\fR(8) for a description of the valid syntax for \fIpattern\fR.
63 \fB\-\-log\-file\fR[\fB=\fIfile\fR]
64 Enables logging to a file. If \fIfile\fR is specified, then it is
65 used as the exact name for the log file. The default log file name
66 used if \fIfile\fR is omitted is \fB@LOGDIR@/\*(PN.log\fR.

69 Send syslog messages to UDP \fIport\fR on \fIhost\fR, in addition to
70 the system syslog. The \fIhost\fR must be a numerical IP address, not
