Struct Syslog 

pub struct Syslog { /* private fields */ }

Encodes LogEvents in RFC 5424 syslog format.

The hostname and app-name fields in the syslog header are configurable at construction time. They default to "sonda" and "sonda" respectively.

Only encode_log is supported. encode_metric returns an error because syslog is a log-only format.

Implementations

impl Syslog

pub fn new(hostname: Option<String>, app_name: Option<String>) -> Self

Create a new Syslog encoder with the given hostname and app-name.

Arguments

• hostname — The HOSTNAME field. Defaults to "sonda" if None.
• app_name — The APP-NAME field. Defaults to "sonda" if None.

Trait Implementations

impl Default for Syslog

fn default() -> Self

Returns the “default value” for a type.

impl Encoder for Syslog

fn encode_metric( &self, _event: &MetricEvent, _buf: &mut Vec<u8>, ) -> Result<(), SondaError>

Syslog encodes only log events. Returns an error for metric events.

fn encode_log( &self, event: &LogEvent, buf: &mut Vec<u8>, ) -> Result<(), SondaError>

Encode a log event as an RFC 5424 syslog line appended to buf.

Format (no labels): <priority>1 timestamp hostname app-name - - - message\n Format (with labels): <priority>1 timestamp hostname app-name - - [sonda k="v" ...] message\n

Priority = (facility * 8) + syslog_severity. Facility 1 (user-level) is used.
