IronDB Persister

This projcet provides a very simple API to ingest RAW metric data into IronDB using flatbuffers.

Ingesting metric data

Ingesting data into a metric is as-easy-as specifying the self-explanatory IRONDB_HOST and IRONDB_PORT environment variables and running the following:

const irondb = require('irondb-persister')

irondb.persist({
    timestamp: Date.now(),
    uuid: '01234567-89ab-cdef-0123-456789abcdef',
    name: 'my_metric_name',
    value: ... ,
  })

Multiple metrics can be ingested in a single call:

const irondb = require('irondb-persister')

irondb.persist([{
    timestamp: Date.now(),
    uuid: '01234567-89ab-cdef-0123-456789abcdef',
    name: 'my_metric_name',
    value: ... ,
  }, {
    timestamp: new Date().toISOString(),
    uuid: 'fedcba98-7654-3210-fedc-ba9876543210',
    name: 'another_metric',
    value: ... ,
  }])

A metric can be ingested by specifying the following required properties:

  • timestamp: the timestamp of the data to persist, either as an ISO-8601 formatted string or as the number of milliseconds from the epoch.
    NOTE: if the number is less than 10000000000 (1970-04-26T17:46:40.000Z) then it will be considered to be the number of seconds from the epoch.
  • uuid: the check UUID of the metric
  • name: the metric name
  • value: the value to persist, either a string, number or null

The following optional properties can also be specified:

  • type: (either number or string) this is required when value is null in order to determine whether to ingest the absent value as a number or as a string
  • checkName: the name to associate with the check
  • account: (defaults to 0 zero) the number of the account to associate with the check
  • tags: an array of key:value tags to associate with the check

Schema

A JSON schema for the metric is available in schema.js

Other functions

The irondb-persister API exposes few other functions for fine-grained control

  • init(host, port): to initialize IronDB programmatically, withou requiring the presence of the two IRONDB_HOST and IRONDB_PORT environment variables.
  • parse(buffer): parse a flatbuffer into either a metric or array thereof.
  • serialize(metricOrArray): serialize a metric, or an array thereof into a CIRM or CIRL flatbuffer.
  • validate(metricOrArray): used before serialization per persistence, this validates that the metric (or array thereof) is syntactically correct
