Products

Issue/Introduction

Symptoms:
How will VMWare Smart Assurance SAM populate the Caused by tab for a notification?
What is the configuration in dynamic modelling to achieve the Caused by tab for a VMWare Smart Assurance SAM notification?

Environment

VMware Smart Assurance - SMARTS

Resolution

The CausedBy or Impact tab comes in because Smarts creates a relationship between any two events based upon the output of the getExplainedBy or getExplains from the underlying domain manager (other than SAM or OI, In case of SAM or OI the notification would already have that relationship).

Usually SAM does not create the events in CausedBy or Impact Tab, it makes the two function call against the event that is coming from the IP domain. The IP domain's model need to have the relationship inorder for SAM to get the CausedBy and Impact.

Therefore if dynamic model is used, the customization/configuration needs to be added in the model file of the IP server which is using it as in the following example:

problem Down = DownOrFlapping
symptom DownOrFlapping = !isUp;
Once the relationship is build as such, then SAM will call causedBy to IP and populate the tab.
