Description

Java RFC5424 formatter library

Using the Syslog Java Client with Maven

Usage

Sourcing timestamp from long

Instant time = Instant.now();
SyslogMessage message = new SyslogMessage()
       .withTimestamp(time.toEpochMilli())
       .withAppName("my_app")
       .withHostname("localhost")
       .withFacility(Facility.USER)
       .withSeverity(Severity.INFORMATIONAL)
       .withMsg("a syslog message");
String actual = message.toRfc5424SyslogMessage();

Sourcing timestamp from Instant

Instant time = Instant.now();
SyslogMessage message = new SyslogMessage()
       .withTimestamp(time)
       .withAppName("my_app")
       .withHostname("localhost")
       .withFacility(Facility.USER)
       .withSeverity(Severity.INFORMATIONAL)
       .withMsg("a syslog message");
String actual = message.toRfc5424SyslogMessage();

Sourcing timestamp from string (parsed and validated)

SyslogMessage message = new SyslogMessage()
       .withTimestamp("2023-06-14T16:37:00.000Z")
       .withAppName("my_app")
       .withHostname("localhost")
       .withFacility(Facility.USER)
       .withSeverity(Severity.INFORMATIONAL)
       .withMsg("a syslog message");
String actual = message.toRfc5424SyslogMessage();

Sourcing timestamp from string (no validation, useful when you know you have correct format)

SyslogMessage message = new SyslogMessage()
       .withTimestamp("2023-06-14T16:37:00.000Z", true)
       .withAppName("my_app")
       .withHostname("localhost")
       .withFacility(Facility.USER)
       .withSeverity(Severity.INFORMATIONAL)
       .withMsg("a syslog message");
String actual = message.toRfc5424SyslogMessage();

Adding structured data

SyslogMessage message = new SyslogMessage()
        .withTimestamp("2023-06-14T16:37:00.000Z")
        .withAppName("my_app")
        .withHostname("localhost")
        .withFacility(Facility.USER)
        .withSeverity(Severity.INFORMATIONAL)
        .withMsg("a syslog message")
        .withSDElement(
            new SDElement(
                "event_version@48577",
                new SDParam("major", "1"),
                new SDParam("minor", "0"),
                new SDParam("version_source", "source")
            )
        );
String actual = message.toRfc5424SyslogMessage();
