Getting Started

Install and add the addon to Mollitia in your application.

# Install mollitia
npm install mollitia --save
# Install the prometheus addon
npm install @mollitia/prometheus --save

// Javascript
const Mollitia = require('mollitia');
const { PrometheusAddon } = require('@mollitia/prometheus');

Mollitia.use(new PrometheusAddon());

Then, add Prometheus options when creating circuits or modules:

const myModule = new Mollitia.Timeout({
    prometheus: {
      name: 'my-module'
    }
});
const myCircuit = new Mollitia.Circuit({
  options: {
    prometheus: {
      name: 'my-circuit',
      labels: {
        tag2: 'val2',
        tag3: 'val3'
      }
    }
  }
});

// ...

const myCircuitMetrics = myCircuit.prometheus.metrics; // Will return an object containing all metrics from this circuit
const myCircuitScrap = myCircuit.prometheus.scrap(); // Will return the Prometheus scrap from this circuit

Finally, you can get Prometheus metrics or scrap like this:

const metrics = Mollitia.metrics(); // Will return an object containing all metrics from all circuits and modules
const scrap = Mollitia.scrap(); // Will return the Prometheus scrap, find an example below
