Usage

const telemetry = require('@telemetry-js/telemetry')()
const logzio = require('@telemetry-js/publisher-logzio-metrics')

telemetry.task()
  .collect(..)
  .schedule(..)
  .publish(logzio, { token: '***' })

Format

Metrics are grouped by time and tags (known as dimensions in Logz.io) into what Logz.io calls a document. Which looks like this:

{
  "type": "custom",
  "token": "***",
  "@timestamp": 1599221440000,
  "metrics": {
    "telemetry.beep.count": 26,
    "telemetry.boop.count": 81,
  },
  "dimensions": {
    "environment": "test"
  }
}

Documents are then sent to Logz.io as NDJSON over TCP. This traffic is not encrypted.

Options

token

String, required. Secret token of Logz.io metrics account. Note that metrics accounts and their tokens are separate from log accounts.

resolution

Expected millisecond interval between repeated metrics. A number or string to be parsed by bruce-millis, default is 1 second. Metrics are grouped by their time, rounded to the nearest multiple of resolution.

If the resolution is too small then no grouping will occur, leading to inefficient documents. If the resolution is too large (i.e. more than your schedule interval or summarize window) then metrics - that have the same name and dimensions within that time window - will be overwritten, only sending the last value to Logz.io.

time

Format of the @timestamp field. The right choice depends on how your Logz.io account is configured to parse timestamps. Can be one of:

• 'ms': unix timestamp in milliseconds (default)
• 'iso': simplified extended ISO
• false: don't add a @timestamp field, in which case metrics take the time at which they're received by Logz.io. If you're unsure which format to use, start with false and inspect raw logs in Logz.io to see which format Logz.io itself adds. Be aware that Logz.io silently drops documents that have an unexpected format.

type

String, default 'custom'. Log type for Logz.io to know how to parse documents.

hostname

String, default 'listener.logz.io'.

port

Number, default 5050.

Install

With npm do:

npm install @telemetry-js/publisher-logzio-metrics
