Overlap Metrics

GET /monitoring/v1/overlapmetrics

The overlap metrics help you understand how many patients have records in multiple source systems.

Overview

Assuming that your Identity service contains records from three sources: AnytownUrgentCare, CommunityClinic, and GeneralHospital, the overlap metrics will report how many patients have records in each pair of sources:

• AnytownUrgentCare and CommunityClinic
• AnytownUrgentCare and GeneralHospital
• CommunityClinic and GeneralHospital

The following example shows that 12 patients have records in both CommunityClinic and GeneralHospital.

    {
      "datasourceA": "CommunityClinic",
      "datasourceB": "GeneralHospital",
      "overlapCount": 12
    }

Prometheus Data Source

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

 # HELP datasource_overlap_count The number of records that can be found in source A and source B
