The Days Mapping Manager allows the traffic light custom fields to be associated with

a Calendar to determine the working days and hours
conditional mappings to determine the color of the traffic light

Accessing Days Mapping Manager

Choose > Issues. Select Days Mapping Manager under the Traffic Light Configuration section
It will display the list of Traffic Light custom fields defined

The columns displayed are

Column Name	Description
Traffic Light Custom Field	The custom field
Traffic Light Calendar	The calendar associated with the Traffic Light custom field If None is selected, then the days will be counted with a 24x7 calendar without any off days.
No. of mapping(s)	The number of mappings defined. Each mapping is a simplified version of JQL and the number of days elapsed for the traffic light SLA to be considered as yellow or red
Actions	The possible actions to configure the mapping: Add - To add the configuration information Edit - To edit the configuration information Reset - To remove existing configuration information

Changing the mapping configuration

By clicking on the Add or Edit action links, it is possible to edit the Mapping Configuration for the Traffic Light custom field

Select the Calendar that the custom field is to be associated with. The change is saved immediately

Specify the JQL condition and the threshold on the number of days to be considered as Yellow and Red

JQL Condition

The issue with the Traffic Light custom field must fulfil the condition in order to use the mapping

It uses a simplified version of JQL which only supports AND and equal operators.
Examples:

Project = "Day Elapsed" AND issuetype = "Bug"
Project = "Day Elapsed" AND issuetype = "Task"

If the JQL condition cannot be evaluated successfully, it will be considered as non-matching

Yellow

The number of days elapsed to be considered as Yellow traffic light.
For example 2 means if day elapsed >= 2, then color is yellow

Red

The number of days elapsed to be considered as Red traffic light. For example 3 means if day elapsed > 3, then color is red

Click on the Add button to save the mapping
Drag the handle on the left side of the JQL condition to sort the sequence of checking
The first matching mapping will be used to determine the color of the traffic light
Click on the Back to Traffic Lights Mapping Configuration button to go back to the Days Mapping Manager

Things to note

While each custom field can have up to 5 conditions, it is recommended to plan the conditions wisely to cover all the possible scenarios and avoid unnecessary checking

Use conditions that checks fields with standard values (e.g. select list, radio buttons, etc) rather than free text values like text field or summary fields
Arrange the ordering of the conditions properly to speed up the processing as the matching is done from top to bottom
- E.g. : If there are 3 priorities defined (Low, Medium, High) and most of the issues are Medium, then the condition with Medium can be ordered as the 1st condition to speed up the matching

The plugin supports only a simplified version of JQL to speed up on the performance
