README
Erlang driver for syslog
This is an erlang port driver for interacting with syslog.
Installing it
./rebar3 compile
Trying it
You should have a look at syslog.h.
In another shell :
$ tail -f /var/log/syslog
Or, for mac users :
$ tail -f /var/log/system.log
In erlang shell :
$ erl
> syslog:start().
> {ok,Log} = syslog:open("Beuha", [cons, perror, pid], local0).
> syslog:log(Log, err, "Damned").
> syslog:log(Log, info, "process count: ~w", [length(processes())]).
API
syslog:open(Ident, Logopt, Facility) -> {ok, port()}
Ident is an arbitrary string
Logopt is an atom or array of atom, you can use a number if you're brave enough :
- pid
- cons
- odelay
- ndelay
- perror
Facility is an atom :
- kern
- user
- daemon
- auth
- syslog
- lpr
- news
- uucp
- cron
- authpriv
- ftp
- netinfo
- remoteauth
- install
- ras
- local0
- local1
- local2
- local3
- local4
- local5
- local6
- local7
The open
call returns either {ok, Log}
where Log is a syslog handle
that can be passed to subsequent log
and close
calls, or it will throw
{error, badarg}.
syslog:log(Log, Priority, Message) -> ok
Log is a syslog handle returned from open
Priority can be a number or better, an atom :
- emerg
- alert
- crit
- err
- warning
- notice
- info
- debug
Message is a string.
syslog:log(Log, Priority, FormatMsg, FormatArgs) -> ok
Same as above, but allows for the construction of log messages similar to
formatting strings via io_lib:format/2
, where FormatMsg indicates the
formatting instructions and FormatArgs is a list of arguments to be
formatted.
syslog:close(Log) -> ok
Log is a syslog handle returned from open
