The Open vSwitch daemons written in C support user-configured logging patterns as described in ovs-appctl(8). This commit adds this capability to the daemons written in Python. - Add a '__log_patterns' attribute to the Vlog class - Populate this using the default patterns in ovs-appctl(8) - Add a '__start_time' attribute to the Vlog class to support '%r' - Update the '_log' method to build the log message according to the pattern - Add a 'set_pattern' method to allow the default patterns to be changed - Update 'set_levels_from_string' to support setting the pattern from a string Signed-off-by: Dave Tucker <dave@dtucker.co.uk> Signed-off-by: Ben Pfaff <blp@nicira.com>

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
|
|
On Windows platform, \fBsyslog\fR is accepted as a word and is only
|
|
useful along with the \fB\-\-syslog\-target\fR option (the word has no
|
|
effect otherwise).

.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.

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\-\-log\-file\fR is also specified (see
|
|
below).
|
|
.IP
|
|
For compatibility with older versions of OVS, \fBany\fR is accepted as
|
|
a word but has no effect.
|
|
.
|
|
.IP "\fB\-v\fR"
|
|
.IQ "\fB\-\-verbose\fR"
|
|
Sets the maximum logging verbosity level, equivalent to
|
|
\fB\-\-verbose=dbg\fR.
|

.

|
.IP "\fB\-vPATTERN:\fIfacility\fB:\fIpattern\fR"
|
|
.IQ "\fB\-\-verbose=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.
|
|
.
|
|
.TP
|
|
\fB\-\-log\-file\fR[\fB=\fIfile\fR]
|
|
Enables logging to a file. If \fIfile\fR is specified, then it is
|
|
used as the exact name for the log file. The default log file name
|
|
used if \fIfile\fR is omitted is \fB@LOGDIR@/\*(PN.log\fR.
|
|
.
|
|
.IP "\fB\-\-syslog\-target=\fIhost\fB:\fIport\fR"
|
|
Send syslog messages to UDP \fIport\fR on \fIhost\fR, in addition to
|
|
the system syslog. The \fIhost\fR must be a numerical IP address, not
|
|
a hostname.
