This page contains example KPI Analyses.

Example 1

The following analysis calculates:

  1. Number of cases
  2. List of case names
  3. List of distinct case names (single case appears only once in the list)

for each event attribute Color and Category.

{
  "Root": "Events",
  "Dimensions": [
    {
      "Name": "Color",
      "Expression": "Color"
    },
    {
      "Name": "Category",
      "Expression": "Category"
    }
  ],
  "Values": [
    {
      "Name": "Count",
      "Expression": "Count(_)" 
    },
    {
      "Name": "Cases",
      "Expression": "StringJoin(\",\", _.Case.Name)" 
    },
    {
      "Name": "DistinctCases",
      "Expression": "StringJoin(\",\", Distinct(_.Case.Name))" 
    }
  ],
  "Ordering": [ 
    {
      "Name": "Color",
      "Direction": "Ascending"
    },
    {
      "Name": "Category",
      "Direction": "Descending"
    }
  ]
}

Example 2

Same analysis for for case attributes:

{
  "Root": "Cases",
  "Dimensions": [
    {
      "Name": "Color",
      "Expression": "Color"
    },
    {
      "Name": "Category",
      "Expression": "Category"
    }
  ],
  "Values": [
    {
      "Name": "Count",
      "Expression": "Count(_)" 
    },
    {
      "Name": "Cases",
      "Expression": "StringJoin(\",\", _.Name)" 
    }
    ],
  "Ordering": [ 
    {
      "Name": "Color",
      "Direction": "Ascending"
    },
    {
      "Name": "Category",
      "Direction": "Ascending"
    }
  ]
}

The following analysis returns a list of all dimensions but doesn't calculate any KPI's:

{
  "Root": "Cases",
  "Dimensions": [
    {
      "Name": "Region",
      "Expression": "Region"
    }
  ]
}

The following analysis calculates a KPI for all filtered data but doesn't slice it to any dimensions:

{
  "Root": "Cases",
  "Values": [
    {
      "Name": "Case count",
      "Expression": "Count(_)" 
    }
    ]
}

	"Root": "Cases",

	"Values": [

Duration

{
  "Root": "Cases",
    "Dimensions": [
      {
        "Name": "TotalHours",
        "Expression": "Duration.TotalHours.Round(0)"
      }
    ],
    "Values": [
      {
        "Name": "Count",
        "Expression": "Count(_)" 
      }
    ],
    "Ordering": [ 
      {
        "Name": "TotalHours",
        "Direction": "Ascending"
    }
  ]
}

The following analysis calculates monthly average case duration. Case start month needs to be a dimension and KPI is the average case duration (also rounding is used).

{
  "Root": "Cases",
  "Dimensions": [
    {
      "Name": "Start Month",
      "Expression": "StartTime.Month"
    }
  ],
  "Values": [
    {
      "Name": "Average Case Duration in Days",
      "Expression": "Round(Average(_.Duration.TotalSeconds) / 3600, 0)"
    }
  ],
  "Ordering": [
    {
      "Name": "Start Month",
      "Direction": "Ascending"
    }
  ]
}
