Performance: Tracked Functions

Tracked Functions essentially allow you to track a sub-transaction or block of code within a larger transaction. For example, they can be implemented for tracking various Elasticsearch queries to uniquely identify them.

First you will need to add the StackifyLib dependency to your app:

PM> Install-Package StackifyLib

Once you have the StackifyLib installed you need to modify your code like shown:

var tracer = StackifyLib.ProfileTracer.CreateAsTrackedFunction("Name of Tracked Function"); 
tracer.Exec(() => 
        //Code to be tracked 

Tracked functions will then show in Retrace in the App Dashboard under Performance(APM+) tab > Tracked Functions tab.

Once you see your Tracked Function in Retrace you can click into it and set this function as a Key Transaction which will allow you to create App monitors around it’s performance.
