Issue/Introduction

We configured a few custom services to monitor on a host using the net_connect probe when we do port scan the status is shown correctly but it is not generating alarm in UIM.

Cause

- nas Required Topology Fault Correlation Rule

Environment

Release : 20.3

Component : UIM NET CONNECT

net_connect - 3.37

robot - 9.32

Uim - 20.31

Resolution

There is a Pre-processing rule that is installed by default that automatically makes all of the net_connect probe alarms invisible. It is called "Required Topology Fault Correlation Rule". You can simply de-activate or modify that pre-processing rule to make the net_connect probe alarms visible. The reason that rule is there is to facilitate implementation of Root Cause Analysis using the fault_correlation_engine which hardly anyone uses. 

Customer disabled rule and the alarms were then visible.
