help
Send syslog messages to network server.
See RFC 5424 (syslog protocol) and RFC 5426 (syslog over UDP) and
RFC 6587 (syslog over TCP) specifications for details.

config LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
bool "Print structured data according to RFC 5424"
help
Print additional structured data as described in
RFC 5424 chapter 6.3. Note that this might increase the
length of the syslog message a lot.
config LOG_BACKEND_NET_RFC5424_SDATA_TZKNOWN
bool "RFC 5424 chapter 7.1.1 tzKnown field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
The tzKnown parameter indicates whether the originator knows its time zone.
See RFC 5424 chapter 7.1 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_ISSYNCED
bool "RFC 5424 chapter 7.1.2 isSynced field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
The isSynced parameter indicates whether the originator is
synchronized to a reliable external time source, e.g., via NTP.
See RFC 5424 chapter 7.1 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_SOFTWARE
bool "RFC 5424 chapter 7.2.3 software description field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
Software description parameter uniquely identifies the software that
generated the message.
See RFC 5424 chapter 7.2 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_SOFTWARE_VALUE
string "RFC 5424 chapter 7.2.3 software field value"
default "zephyr"
depends on LOG_BACKEND_NET_RFC5424_SDATA_SOFTWARE
help
User defined value for the software field.
See RFC 5424 chapter 7.2.3 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_SOFTWARE_VERSION
bool "RFC 5424 chapter 7.2.4 software version field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
Software version parameter uniquely identifies the software that
generated the message.
See RFC 5424 chapter 7.2.4 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_SEQID
bool "RFC 5424 chapter 7.3.1 sequence id field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
Sequence id parameter tracks the sequence in which the
originator submits messages to the syslog transport for sending.
See RFC 5424 chapter 7.3.1 for details.
config LOG_BACKEND_NET_RFC5424_SDATA_UPTIME
bool "RFC 5424 chapter 7.3.2 system uptime field"
depends on LOG_BACKEND_NET_RFC5424_STRUCTURED_DATA
help
The system uptime parameter tracks the "time (in hundredths of a
second) since the network management portion of the system was last
re-initialized." For Zephyr this is currently interpreted as the
system uptime.
See RFC 5424 chapter 7.3.2 for details.
config LOG_BACKEND_NET_SERVER
string "Syslog server IP address"
help
This can be either IPv4 or IPv6 address.
Server listen UDP port number can be configured here too.
Following syntax is supported:
192.0.2.1:514
192.0.2.42
[2001:db8::1]:514
[2001:db8::2]
2001:db::42
If you want to use TCP, add "tcp://" in front of the address
like this
tcp://192.0.2.1:514
tcp://192.0.2.42
tcp://[2001:db8::1]:514
UDP is used by default if the URI is missing.
config LOG_BACKEND_NET_MAX_BUF_SIZE
int "Max syslog message size"
range 64 1180
default 1180 if NET_IPV6
default 480 if NET_IPV4
default 256
help
As each syslog message needs to fit to UDP packet, set this value
so that messages are not truncated.
The RFC 5426 recommends that for IPv4 the size is 480 octets and for
IPv6 the size is 1180 octets. As each buffer will use RAM, the value
should be selected so that typical messages will fit the buffer.
config LOG_BACKEND_NET_AUTOSTART
bool "Automatically start networking backend"
default y if NET_CONFIG_NEED_IPV4 || NET_CONFIG_NEED_IPV6
help
When enabled automatically start the networking backend on
application start. If no routes to the logging server are available
on application startup, this must be set to n and the backend must be
started by the application later on. Otherwise the logging
thread might block.
config LOG_BACKEND_NET_USE_DHCPV4_OPTION
bool "Use DHCPv4 Log Server Option to configure syslog server"
depends on NET_DHCPV4
help
When enabled the syslog server IP address is read from the DHCPv4
Log Server Option (7).
