C bindings to syslog and a fast, more feature-rich console module.
$ npm install rconsole
By default your syslogs will land in
/var/log/messages. Add a new
facility where your syslog configuration is located to change this. (see notes)
Here is an example webserver that pipes
express.logger to the stream for notice severity logs. It includes
production configuration. Create a new file called
app.js with the following code:
var express =app = expressappappapp// pass in the stream to console.noticeappappappconsole
Start the server
$ node app.js
And then visit http://localhost:3000/ and express.logger will be streaming to
console.notice in your terminal as well as syslog.
To disable the stderr stream, start the app with
NODE_ENV=production and then
tail -f /var/log/path/to/logFile to monitor the logs
$ NODE_ENV=production node app.js

The default configuration is suited for development, however you should immediately set up configuration for syslog and choose a facility (local0-local7) that is not already in use on your system.
By default your syslogs will land in
/var/log/messages with facility
user and tag
node. Configure a new
/etc/syslog-ng.conf or wherever your syslog configuration is located.
For rsyslog your configuration might look something like this:
local0.notice /var/log/node/production.loglocal0.info /var/log/node/staging.loglocal0.debug /var/log/node/debug.log
rconsole provides display features and is a drop in replacement for the native
console will come with a number of options that you can
console.set (see the api)
If you completely disable stderr/stdout you can just tail your syslogs.
The aim of this module is to provide an interface to
syslog.h based on the syslog RFC (http://tools.ietf.org/html/rfc5424). Any configuration that can be done with rsyslog or syslog-ng is not provided in this module; such as log reception, forwaring, filtering, etc. The archival destinations are not visible to or configurable by the app, and instead are completely managed by the execution environment.
