Multiple file transports in using Winston - node.js

Question

I am attempting to use multiple transports in Winston. This is working...sorta. I have a transport set up for the app's audit log, with a custom level of 'audit', and a transport for 'info'.
var winston_mongo_options = {
level: 'audit', // level that should be logged
safe: true, //makes sure writes happen before firing log event
db: config.db.db, // db in which to write logs
host: config.db.host,
port: config.db.port,
collection: config.db.audit_collection // collection we want logging to occur
};
if (config.db.user) {
winston_mongo_options.username = config.db.user;
winston_mongo_options.password = config.db.pass;
}
var custom_levels = winston.config.syslog.levels;
custom_levels.audit = 8;
var logger = new (winston.Logger)({
levels: custom_levels,
transports : [
new (winston.transports.MongoDB)(winston_mongo_options),
new (winston.transports.File)({
level: 'info',
silent: false,
colorize: true,
timestamp: true,
filename: config.logs.debug,
maxsize: 500000,
maxFiles: 5,
json: true
})
],
exceptionHandlers: [
new (winston.transports.File)({
silent: false,
colorize: false,
timestamp: true,
filename: config.logs.exception,
maxsize: 500000,
maxFiles: 5,
json: true
})
]
});
module.exports.logger = logger;
Obviously, I'm requiring this file where/when I want to do any logging. The problem comes in when wanting to send certain information separately to the logs.
logger.audit('Server Started - to DB');
logger.info('Server Started - to info');
These two lines should write to separate logs. The first line gets properly written to the database AND to the info log file. What am I doing wrong?

SOLVED: The problem was how I am defining the levels. I didn't realize that the way Winston logging works, is a log will receive everything >= the level defined. So my 'info' transport being a level 0 was receiving messages sent to the 'audit' transport, which was a level 8. I set 'audit' to level 0, and it stopped showing up in the 'info' log. I then found a better solution by creation a whole new logger just for the audit database log.
