-t
--timeout=secs
Limits ovs-dpctl runtime to approximately secs seconds.
If the timeout expires, ovs-dpctl will exit with a SIGALRM
signal.
-v[spec]
--verbose=[spec]
Sets logging levels. Without any spec, sets the log level
for every module and destination to dbg. Otherwise, spec
is a list of words separated by spaces or commas or
colons, up to one from each category below:
• A valid module name, as displayed by the vlog/list
command on ovs-appctl(8), limits the log level
change to the specified module.
• syslog, console, or file, to limit the log level
change to only to the system log, to the console,
or to a file, respectively. (If --detach is
specified, ovs-dpctl closes its standard file
descriptors, so logging to the console will have no
effect.)
On Windows platform, syslog is accepted as a word
and is only useful along with the --syslog-target
option (the word has no effect otherwise).
• off, emer, err, warn, info, or dbg, to control the
log level. Messages of the given severity or
higher will be logged, and messages of lower
severity will be filtered out. off filters out all
messages. See ovs-appctl(8) for a definition of
each log level.
Case is not significant within spec.
Regardless of the log levels set for file, logging to a
file will not take place unless --log-file is also
specified (see below).
For compatibility with older versions of OVS, any is
accepted as a word but has no effect.
-v
--verbose
Sets the maximum logging verbosity level, equivalent to
--verbose=dbg.
-vPATTERN:destination:pattern
--verbose=PATTERN:destination:pattern
Sets the log pattern for destination to pattern. Refer to
ovs-appctl(8) for a description of the valid syntax for
pattern.
-vFACILITY:facility
--verbose=FACILITY:facility
Sets the RFC5424 facility of the log message. facility can
be one of kern, user, mail, daemon, auth, syslog, lpr,
news, uucp, clock, ftp, ntp, audit, alert, clock2, local0,
local1, local2, local3, local4, local5, local6 or local7.
If this option is not specified, daemon is used as the
default for the local system syslog and local0 is used
while sending a message to the target provided via the
--syslog-target option.
--log-file[=file]
Enables logging to a file. If file is specified, then it
is used as the exact name for the log file. The default
log file name used if file is omitted is
/usr/local/var/log/openvswitch/ovs-dpctl.log.
--syslog-target=host:port
Send syslog messages to UDP port on host, in addition to
the system syslog. The host must be a numerical IP
address, not a hostname.
--syslog-method=method
Specify method how syslog messages should be sent to
syslog daemon. Following forms are supported:
• libc, use libc syslog() function. Downside of
using this options is that libc adds fixed prefix
to every message before it is actually sent to the
syslog daemon over /dev/log UNIX domain socket.
• unix:file, use UNIX domain socket directly. It is
possible to specify arbitrary message format with
this option. However, rsyslogd 8.9 and older
versions use hard coded parser function anyway that
limits UNIX domain socket use. If you want to use
arbitrary message format with older rsyslogd
versions, then use UDP socket to localhost IP
address instead.
• udp:ip:port, use UDP socket. With this method it
is possible to use arbitrary message format also
with older rsyslogd. When sending syslog messages
over UDP socket extra precaution needs to be taken
into account, for example, syslog daemon needs to
be configured to listen on the specified UDP port,
accidental iptables rules could be interfering with
local syslog traffic and there are some security
considerations that apply to UDP sockets, but do
not apply to UNIX domain sockets.
• null, discards all messages logged to syslog.
The default is taken from the OVS_SYSLOG_METHOD
environment variable; if it is unset, the default is libc.
-h
--help Prints a brief help message to the console.
-V
--version
Prints version information to the console.
