logzio-nodejs

NodeJS logger for LogzIO. The logger stashes the log messages you send into an array which is sent as a bulk once it reaches its size limit (100 messages) or time limit (10 sec) in an async fashion. It contains a simple retry mechanism which upon connection reset (server side) or client timeout, wait a bit (default interval of 2 seconds), and try this bulk again (it does not block other messages from being accumulated and sent (async). The interval increases by a factor of 2 between each retry, until we reached the maximum allowed attempts (3).

By default any error is logged to the console. This can be changed by supplying a callback function.

Sample usage

var logger = require('logzio-nodejs').createLogger({
    token: '__YOUR_API_TOKEN__',
    type: 'YourLogType'     // OPTIONAL (If none is set, it will be 'nodejs')
});


// sending text
logger.log('This is a log message');

// sending an object
var obj = { 
    message: 'Some log message', 
    param1: 'val1',
    param2: 'val2'
};
logger.log(obj);

Options

• token Mandatory. Your API logging token. Look it up in the Device Config tab in Logz.io
• type - Log type. Help classify logs into different classifications
• protocol - 'http' or 'https'. Default: http
• sendIntervalMs - Time in milliseconds to wait between retry attempts. Default: 2000 (2 sec)
• bufferSize - The maximum number of messages the logger will accumulate before sending them all as a bulk. Default: 100.
• numberOfRetries - The maximum number of retry attempts. Default: 3
• debug - Should the logger print debug messages to the console? Default: false
• callback - a callback function called when an unrecoverable error has occured in the logger. The function API is: function(err) - err being the Error object.
• timeout - the read/write/connection timeout in milliseconds.
