Identifier Metrics

GET /monitoring/v1/identifiermetrics

The identifier metrics help you understand:

• How many records you have stored.
• How often different kinds of demographic identifiers are found in your records.
• What kind and how many demographic identifiers different data sources provide.

Overview

There are two parts to the identifier metrics: global metrics (across all sources), and source-specific metrics.

Global Metrics

The global metrics show how many total records and total unique persons you have (in this case 16,400 and 8,287 respectively):

  "totalRecordCount": 16400,
  "totalPersonCount": 8287,

There is also a report showing how often each demographic identifier appears in records. For example, the following data shows that 16,125 out of 16,400 records (over 98%) contained a date of birth:

  "globalMetricsRecords": [ 
    {
      "identifierType": "DOB",
      "recordCount": 16125,
      "recordRatio": 0.9832317,
      "source": ""
    },
    ...
  ]

The empty source field indicates that the record count/ratio are for all source systems.

Identifier Types

Available identifier types include: City, DOB, Email, FirstName, Gender, HighwayNumber, HighwayPrefix, LastFourSSN, LastName, MaidenName, MiddleName, Ordinal, PO, POBoxNumber, PhoneNumber, SSN, State, StreetFraction, StreetName, StreetNumber, StreetNumberAlpha, StreetType, UnitNumber, UnitNumberAlpha, UnitType, ZipCode, and ZipCodeExtension.

Source-Specific Metrics

If you need to dig deeper into a specific source system, or examine differences between sources, the summaryMetricsRecords and sourceTotals fields give breakdowns by source. For example:

  "summaryMetricsRecords": [ 
    {
      "identifierType": "DOB",
      "recordCount": 753,
      "recordRatio": 0.7150997,
      "source": "CommunityClinic"
    },
    {
      "identifierType": "DOB",
      "recordCount": 1811,
      "recordRatio": 0.9810244,
      "source": "GeneralHospital"
    },
    ...
  ],
  "sourceTotals": [ 
    {
      "source": "CommunityClinic",
      "totalRecordCount": 1053
    },
    {
      "source": "GeneralHospital",
      "totalRecordCount": 1846
    },
    ...
  ]

Putting these two lists together, you can conclude:

This data shows that Community Clinic is sending dates of birth at a lower rate than General Hospital, which could result in downstream issues with matching.

Prometheus Data Source

When you provide an accept parameter of text/plain in the HTTP request header, the Identity service will provide metrics in a format suitable for use as a Prometheus data source.
