Preventing event 0x10d35 Alarms for pingables in a Specific Global Collection

Products

Issue/Introduction

A user wants to prevent the default 0x00010d35 (DEVICE HAS STOPPED RESPONDING TO POLLS) alarm from being generated for a specific group of pingables categorized in a Global Collection (GC). 

Environment

• Product: DX NetOps Spectrum
• Component: Fault Isolation / Alarm Management
• Version: All supported versions

Cause

The 0x10d35 event is part of Spectrum's core Fault Isolation logic. The Inference Handler (IH) monitors device connectivity and asserts this alarm based on internal algorithms. Directly modifying this event in `EventDisp` is discouraged and often overridden by the IH, which can lead to unpredictable behavior or "Fault Isolation Event is customized" warnings.

Resolution

The easiest way to achieve this behavior for pingable-only devices is by setting the `value_when_red` attribute (0x1000b) to `0`.  This will prevent the alarm, but this applies to the model itself and is not specific to a Global Collection.
