The goal of node-telemetry is to make it really easy to deploy a scalable telemetry server for small projects. This can be used to capture errors, performance data, and more, and store it in a document store or on the filesystem.

To install telemetry, run

npm install -g telemetry

then edit your config.yaml, and run telemetry:

telemetry

An example config.yaml is provided below:

errors:
  -
    type: couchdb
    host: user.cloudant.com
    username: user
    password: password

You may place this in the same directory as telemetry, or pass it via the TELEMETRY_CONFIG environment variables like so:

export TELEMETRY_CONFIG=~/.telemetry; telemetry

Events can be sent to node-telemetry by any HTTP client capable of a POST. For javascript on the browser, you can use janky.post. Here's an example of what that would look like:

var data = {
    level: "log",
    message: "Invalid identifier: theCheat",
    lineNumber: 25,
    file: "strongbad.js"
};

janky({
    url: "http://example.com/inputs/errors",
    method: "post",
    data: data,
    error: function() {
        console.log("Could not reach telemetry server");
    }
});

If you are interested in creating additional backends for telemetry, or need general assistance, contact me using the e-mail address displayed when you do

npm author ls telemetry
