+# Count open Incidents per Priority and State using GlideAggregate
+
+## Overview
+This script will dynamically calculate the **number of open incidents** for each priority level and also give you a total for what 
+current state the Incident is in using **server-side scripting**
+Priority levels typically include:  
++ 1 – Critical  
++ 2 – High  
++ 3 – Moderate  
++ 4 – Low
+
+Incident State typically include:
++ New
++ In Progress
++ On Hold
++ Resolved
++ Closed
++ Canceled
+
+The scripting solution leverages **GlideAggregate** to efficiently count records grouped by priority and state. This scripts approach
+is useful for:
++ Dashboards
++ Business Rules
++ SLA monitoring and reporting
+
+--
+## Table and Fields
++ **Table:** Task
++ **Fields:** Priority, State
