IOpipe Analytics & Distributed Tracing Agent

This package provides analytics and distributed tracing for event-driven, "serverless" applications.

Installation & usage

Installation is simple. Just require this module with your client id (contact us to get set up) and it will automatically monitor and collect metrics from your application running on AWS Lambda, Google Cloud Functions, Azure, or any other "serverless" environment.

Example:

var iopipe_metrics = require("iopipe-agent")({ clientId: "YOUR_ID"})

exports.handle = iopipe_metrics(
  function (event, context) {
    context.succeed("This is my serverless function!")
  }
)

Configuration

When requiring the metrics agent, it accepts a config object where you define the URL for the collector service and a client id. By default, telemetry will be reported to the IOpipe Telemetry Service.

var config = {
    url: "https://metrics-api.iopipe.com", // This is the default value
    clientId: "YOUR_ID"
}
var iopipe_metrics = require("iopipe-agent")(config)

To override the collector service, specify a URL (ex. "127.0.0.1") running the IOpipe Collector as follows:

var iopipe_metrics = require("iopipe-agent")({ url: "https://127.0.0.1", clientId: "YOUR_ID" })

exports.handle = iopipe_metrics(
  function (event, context) {
    context.succeed("Reporting these metrics to my own collector!")
  }
)

Data reported

The following is provided to the collector service, either the IOpipe Telemetry Service or the open serverless collector.

• function_id (a hashed identifier of the function)
• client_id (your client id, common among all your functions)
• environment (restricted view of Node's process var)
• errors
• events (custom events sent via .emit('event', [data])
• time_sec_nanosec (execution time: [secs, nanosecs])
• time_sec (execution time: secs)
• time_nanosec (execution time: nanosecs)
