Syslogparser
============

This is a syslog parser for the Go programming language.


Installing
----------

go get github.com/jeromer/syslogparser


Supported RFCs
--------------

RFC 3164 : https://tools.ietf.org/html/rfc3164
RFC 5424 : https://tools.ietf.org/html/rfc5424

Not all features described in RFCs above are supported but only the most part of
it. For exaple SDIDs are not supported in RFC5424 and STRUCTURED-DATA are
parsed as a whole string.

This parser should solve 80% of use cases. If your use cases are in the 20%
remaining ones I would recommend you to fully test what you want to achieve and
provide a patch if you want.

Parsing an RFC 3164 syslog message
----------------------------------

	b := "<34>Oct 11 22:14:15 mymachine su: 'su root' failed for lonvick on /dev/pts/8"
	buff := []byte(b)

	p := rfc3164.NewParser(buff)
	err := p.Parse()
	if err != nil {
		panic(err)
	}

	for k, v := range p.Dump() {
		fmt.Println(k, ":", v)
	}

You should see

    timestamp : 2013-10-11 22:14:15 +0000 UTC
    hostname  : mymachine
    tag       : su
    content   : 'su root' failed for lonvick on /dev/pts/8
    priority  : 34
    facility  : 4
    severity  : 2

Parsing an RFC 5424 syslog message
----------------------------------

	b := `<165>1 2003-10-11T22:14:15.003Z mymachine.example.com evntslog - ID47 [exampleSDID@32473 iut="3" eventSource="Application" eventID="1011"] An application event log entry...`
	buff := []byte(b)

	p := rfc5424.NewParser(buff)
	err := p.Parse()
	if err != nil {
		panic(err)
	}

	for k, v := range p.Dump() {
		fmt.Println(k, ":", v)
	}

You should see

    version : 1
    timestamp : 2003-10-11 22:14:15.003 +0000 UTC
    app_name : evntslog
    msg_id : ID47
    message : An application event log entry...
    priority : 165
    facility : 20
    severity : 5
    hostname : mymachine.example.com
    proc_id : -
    structured_data : [exampleSDID@32473 iut="3" eventSource="Application" eventID="1011"]
