Library: Net
Package: Logging
Header: Poco/Net/RemoteSyslogChannel.h

Description

Constructors

RemoteSyslogChannel

RemoteSyslogChannel();

Creates a RemoteSyslogChannel.

RemoteSyslogChannel

RemoteSyslogChannel(
    const std::string & address,
    const std::string & name,
    int facility = SYSLOG_USER,
    bool bsdFormat = false
);

Creates a RemoteSyslogChannel with the given target address, name, and facility. If bsdFormat is true, messages are formatted according to RFC 3164.

Destructor

~RemoteSyslogChannel

~RemoteSyslogChannel();

Member Functions

close

void close();

Closes the RemoteSyslogChannel.

getProperty

std::string getProperty(
const std::string & name
) const;

Returns the value of the property with the given name.

See also: Poco::Channel::getProperty()

log

void log(
const Message & msg
);

Sends the message's text to the syslog service.

See also: Poco::Channel::log()

open

void open();

Opens the RemoteSyslogChannel.

See also: Poco::Channel::open()

registerChannel

static void registerChannel();

Registers the channel with the global LoggingFactory.

setProperty

void setProperty(
const std::string & name,
const std::string & value
);

Sets the property with the given value.

The following properties are supported:

name: The name used to identify the source of log messages.
facility: The facility added to each log message. See the Facility enumeration for a list of supported values. The LOG_ prefix can be omitted and values are case insensitive (e.g. a facility value "mail" is recognized as SYSLOG_MAIL)
format: "bsd"/"rfc3164" (RFC 3164 format) or "new"/"rfc5424" (default)
loghost: The target IP address or host name where log messages are sent. Optionally, a port number (separated by a colon) can also be specified.
host: (optional) Host name included in syslog messages. If not specified, the host's real domain name or IP address will be used.
