Until now, the argument to -v and vlog/set has had to take the form "module:facility:level". I can never remember the required order, so this commit switches to allowing any order. Signed-off-by: Ben Pfaff <blp@nicira.com>

.SS "VLOG COMMANDS"
|
|
These commands manage \fB\*(PN\fR's logging settings.
|
|
.IP "\fBvlog/set\fR [\fIspec\fR]"
|
|
Sets logging levels. Without any \fIspec\fR, sets the log level for
|
|
every module and facility to \fBdbg\fR. Otherwise, \fIspec\fR is a
|
|
list of words separated by spaces or commas or colons, up to one from
|
|
each category below:
|
|
.
|
|
.RS
|
|
.IP \(bu
|
|
A valid module name, as displayed by the \fBvlog/list\fR command on
|
|
\fBovs\-appctl\fR(8), limits the log level change to the specified
|
|
module.
|
|
.
|
|
.IP \(bu
|
|
\fBsyslog\fR, \fBconsole\fR, or \fBfile\fR, to limit the log level
|
|
change to only to the system log, to the console, or to a file,
|
|
respectively.
|
|
.
|
|
.IP \(bu
|
|
\fBoff\fR, \fBemer\fR, \fBerr\fR, \fBwarn\fR, \fBinfo\fR, or
|
|
\fBdbg\fR, to control the log level. Messages of the given severity
|
|
or higher will be logged, and messages of lower severity will be
|
|
filtered out. \fBoff\fR filters out all messages. See
|
|
\fBovs\-appctl\fR(8) for a definition of each log level.
|
|
.RE
|
|
.
|
|
.IP
|
|
Case is not significant within \fIspec\fR.
|
|
.IP
|
|
Regardless of the log levels set for \fBfile\fR, logging to a file
|
|
will not take place unless \fB\*(PN\fR was invoked with the
|
|
\fB\-\-log\-file\fR option.
|
|
.IP
|
|
For compatibility with older versions of OVS, \fBany\fR is accepted as
|
|
a word but has no effect.
|
|
.RE
|
|
.IP "\fBvlog/set PATTERN:\fIfacility\fB:\fIpattern\fR"
|
|
Sets the log pattern for \fIfacility\fR to \fIpattern\fR. Refer to
|
|
\fBovs\-appctl\fR(8) for a description of the valid syntax for \fIpattern\fR.
|
|
.
|
|
.IP "\fBvlog/list\fR"
|
|
Lists the supported logging modules and their current levels.
|
|
.
|
|
.IP "\fBvlog/reopen\fR"
|
|
Causes \fB\*(PN\fR to close and reopen its log file. (This is useful
|
|
after rotating log files, to cause a new log file to be used.)
|
|
.IP
|
|
This has no effect unless \fB\*(PN\fR was invoked with the
|
|
\fB\-\-log\-file\fR option.
