hrbr-ferryboat

Parses lines from log files, converts each line to a beacon message, sends a beacon message to (https://hrbr.io).

If you are looking for a working example then you should check out the ferryboat-cli which is a command line interface for sending output from log files to hrbr.io using this module.

Sample Implementation

Here is a sample javascript implementation:

const ferryboat = require('hrbr-ferryboat');
 
const grokPattern = "%{COMMONAPACHELOG}";
const beaconOpts = {
    apiKey: "8675309",
    appVersionId: "com.myco.syslog:1.0.0",
    beaconVersionId: "com.myco.groklog:1.0.0",
    bufferOptions: {
        lengthLimit: 100000
    },
    interMessageDelayMs: 1
};
const messageType = "MYAPACHE_LOG";
 
const processLines = async () => {
 
    const lines = [

To try the sample code do:

$ mkdir myfirstbeacon
cd myfirstbeacon
$ npm init -y
$ npm install -S hrbr-ferryboat
# Save the above code as index.js 
# Be sure to replace apiKey, appVersionId, beaconVersionId in your code. 
$ npm update
$ node index.js
