A Collector that collects data using 'appmetrics' and exposes it to a path "/metrics".

The appmetrics-prometheus-client Collector for Node Application Metrics can be installed via npm:

$ npm install appmetrics-prometheus-client

The Collector can be used in your application by requiring it as the first line of your application:

const appmetrics_prometheus = require('appmetrics-prometheus-client').Prometheus();

The Collector sends the following data values to Path /metrics from Node Application Metrics:

Gauges

• cpu.process the CPU usage of the application as a percentage of total machine CPU
• cpu.system the CPU usage of the system as a percentage of total machine CPU

Gauges

• memory.process.private the amount of memory used by the Node.js application that cannot be shared with other processes, in bytes.
• memory.process.physical the amount of RAM used by the Node.js application in bytes.
• memory.process.virtual the memory address space used by Node.js application in bytes.
• memory.system.used the total amount of RAM in use on the system in bytes.
• memory.system.total the total amount of RAM available on the system in bytes.

• eventloop.latency.min the shortest sampled latency for processing an event
• eventloop.latency.max the longest sampled latency for processing an event
• eventloop.latency.avg the mean sampled latency for processing an event

Gauges

• gc.size the size of the JavaScript heap in bytes.
• gc.used the amount of memory used on the JavaScript heap in bytes.

Timers

• gc.duration the duration of the GC cycle in milliseconds.

Timers

• http the time taken for the HTTP request to be responded to in ms.
