QPR ProcessAnalyzer Expression Examples

The following examples assume that there is a filter with id 1. point. All KPI analyses also have an EventLog as a starting point, so expression written after the "EventLogById(1)." is a valid expression for KPI Analyses.

Get all event types that appear among the events:

EventLogById(1).EventTypes

Same as previous, except return event type names (Strings):

EventLogById(1).EventTypes.Name

Get a hierarchical array, where the upper level are EventTypes and the leaf level are Events:

EventLogById(1).EventTypes.Events

Get a hierarchical array, where the upper level are EventTypes and the leaf level are also EventTypes (all branches contain same EventTypes):

EventLogById(1).EventTypes:Events.Type

EventLogById(1).EventTypes:Events.TimeStamp

List all Events as leaf nodes which timestamp is after 2012-01-01:

EventLogById(1).EventTypes:Events.Where(Timestamp > DateTime(2012,1,1))

Calculates count of Events in the leaf nodes:

Count(EventLogById(1).EventTypes:Events.Where(Timestamp > DateTime(2012,1,1)))

Events are ordered beginning from the last one:

EventLogById(1).EventTypes.OrderByDescending(Events, Timestamp)

Same as the previous but with explicit context specified:

EventLogById(1).EventTypes.OrderByDescending(_.Events, _.Timestamp)

Shows all event types in a single comma separated string list:

EventLogById(1).(StringJoin(", ", EventTypes.Name))

Same as the previous, except in addition the EventTypes are ordered by name:

EventLogById(1).(StringJoin(", ", OrderByDescending(EventTypes, Name).Name))

List of all the Starter flows in a model from filterId=1:

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_)))

Go through the model recursively using the flows:

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_))).To.OutgoingFlows.To.OutgoingFlows.To

Traverse the model using events:

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_))).FlowOccurrences.To.NextInCase.NextInCase.NextInCase

All case attribute values within the model grouped by case attribute types:

Let("cases", EventLogById(1).Cases, EventLogById(1).CaseAttributes:(Let("attribute", _, cases.Attribute(attribute))))

All event attribute values within the model grouped by event attribute types:

Let("events", EventLogById(1).Events, EventLogById(1).EventAttributes:(Let("attribute", _, events.Attribute(attribute))))

Define a new user defined functions named "First", which takes the first item in an array:

Def("First", "a", GetAt(0, a));

The defined array can be used as follows:

First(Array(1, 2, 3))
returns: 1

Def("x", "a", Distinct(RecurseLeaves(OrderBy(EventLogById(a).Cases.Events, Type.Name), Type.Name)))

Function definition that uses itself, i.e. recursive functions:

Def("Fib", "a", If(a < 2, 1, Fib(a - 1) + Fib(a - 2)));
For("i", 0, i < 10, i + 1, Fib(i));

Takas all models, and show them in "id:name" format:

Models.StringJoin(":", [Id, Name])

Models.[Id, Name]
