Hi Pradeep,

Please find below differences between TAF v2 & v3

Triggered Automation Framework Version2

Triggered Automation Framework Version3

Run book based triggered Automation framework.

Intent based triggered automation framework

 

Runbooks with automation assets [DVT, Q App etc] can be triggered from ITSM tool

Intents / intent cluster / intent Templates can be triggered from email, MS teams chatbot, ITSM /Service Now.

Configuration workflow

  • Download and install NetBrain connecter v2 from SNOW App store.
  • Configure NetBrain connector in SNOW [ Key parameters – Endpoint, Authentication, Tenant, Domain ID]
  • Configure Shared Data field in SNOW to define what incident fields should be sent to NetBrain during event trigger.
  • Configure Automation template and trigger rule to define when and how to trigger NetBrain during an event/incident
  • Configure API Stub and API Trigger template in NetBrain to filter incoming incidents and trigger required Run Books and dynamic maps.

Configuration workflow

  • Download and Install NetBrain connecter v3 from SNOW App store.
  • Configure NetBrain connector in SNOW [ Key parameters – Endpoint, Authentication, Tenant, Domain ID]
  • Configure Shared Data field in SNOW to define what incident fields should be sent to NetBrain during event trigger.
  • Configure Trigger rule in Service now with condition to trigger NetBrain. [Ex: short_desc contains “VPN Down”]
  • Configure “Incoming incident type” to filter incoming incidents. [key parameters to configure – Source, filter condition]
  • Associate the incident type with network intent / intent cluster / Intent template so that filtered incoming incidents will trigger network intents.

 

         

 

 

 

  • This triggered automation will execute on the live data pulled as there is no baseline in the automation assets in this TAF version.
  • Automation assets that are built part of runbook requires no code or low code.
  • Network intents have baseline hence we can perform comparison between current [live data] and baseline in this TAF version.
  • No Coding knowledge is required to build Network Intents and TAF v3
  • In this TAF version Users can interactively execute the runbooks once the diagnosis and map are triggered by an event.
