Severe alarm delay processing UIM trap through SouthBound Gateway

Products

• CA Spectrum

Issue/Introduction

After upgrading from Spectrum 10.3.0 to 10.4.x we are experiencing severe alarm delays processing UIM traps through SouthBound Gateway.

Environment

Release : 20.2

Component : Spectrum Core / SpectroSERVER

Resolution

The "getRemoteDevModelsByName" call tries to find models in other landscapes by name if  the "SBGW_AlertForwardingEnabled" attribute on the Event Admin model is set to true.

With a high load (around 500K traps per hour) these searches can cause a delay.

Setting the SBGW_AlertForwardingEnabled to false disables this name query.

Provided all of the UIM entities on which the UIM alarms are being raised are on the MLS so there is no need for "SBGW_AlertForwardingEnabled" to be enabled.
