winston-logzio is a winston plugin and wrapper for the logzio-nodejs appender. With winston-logzio, you can take advantage of the winston logger framework with your Node.js app.
Supports Winston 3, If you want to use Winston 2 - Checkout v1.0.8
npm install winston-logzio --save
Use the samples in the code block below as a starting point, and replace the sample with a configuration that matches your needs.
To run with Typescript click here.
const winston = require('winston');
const LogzioWinstonTransport = require('winston-logzio');
const logzioWinstonTransport = new LogzioWinstonTransport({
level: 'info',
name: 'winston_logzio',
token: '<<SHIPPING-TOKEN>>',
host: '<<LISTENER-HOST>>',
});
const logger = winston.createLogger({
format: winston.format.simple(),
transports: [logzioWinstonTransport],
});
logger.log('warn', 'Just a test message');
Replace <<SHIPPING-TOKEN>>
with your own logz.io logs shipping token.
Replace <<LISTENER-HOST>>
with your region’s listener host (for example, listener.logz.io).
For more parameters for LogzioWinstonTransport and configuration options see our docs.

- token Mandatory. Your account token. Look it up in the Device Config tab in Logz.io
- type - Log type. Help classify logs into different classifications
- protocol -
http
,https
orudp
. Default:http
- host - Destination host name. Default:
listener.logz.io
- port - Destination port. Default port depends on protocol. For
udp
default port is5050
, forhttp
is8070
and8071
is forhttps
- 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.
- addTimestampWithNanoSecs - Add a timestamp with nano seconds granularity. This is needed when many logs are sent in the same millisecond, so you can properly order the logs in kibana. The added timestamp field will be
@timestamp_nano
Default:false
- compress - If true the the logs are compressed in gzip format. Default:
false
- internalLogger - set internal logger that supports the function log. Default: console.
- setUserAgent - Set to
false
to send logs without the user-agent field in the request header. Default:true
. If you want to send data from Firefox browser, set that option tofalse
. - extraFields - Adds your own custom fields to each log. Add in JSON Format, for example:
extraFields : { field_1: "val_1", field_2: "val_2" , ... }
.
This winston plugin, basically just wraps our nodejs logzio shipper.
If you want to configure the nodejs logger, any parameters sent to winston when initializing the transport
(what is held in the variable LogzioWinstonTransport
in the sample above) will be passed to the logzio nodejs logger itself.
The winston logger by default sends all logs to the console.
You can easily disable this by adding this line to your code :
winston.remove(winston.transports.Console);
If you don't have a 'tsconfig.json' file start by running:
tsc --init
On your 'tsconfig' file, under 'compilerOptions' make sure you have 'esModuleInterop' flag with the value 'true' or add it this way:
"compilerOptions": {
...
"esModuleInterop": true
}
Code sample:
import winston from 'winston';
import LogzioWinstonTransport from 'winston-logzio';
const logzioWinstonTransport = new LogzioWinstonTransport({
level: 'info',
name: 'winston_logzio',
token: '<<SHIPPING-TOKEN>>',
host: '<<LISTENER-HOST>>',
});
const logger = winston.createLogger({
format: winston.format.simple(),
transports: [logzioWinstonTransport],
});
logger.log('warn', 'Just a test message');
Replace <<SHIPPING-TOKEN>>
with your own logz.io logs shipping token.
Replace <<LISTENER-HOST>>
with your region’s listener host (for example, listener.logz.io).

Note: If winston-logzio is used as part of a serverless service (AWS Lambda, Azure Functions, Google Cloud Functions, etc.), add logger.close()
at the end of the run.
