Issue/Introduction

Traps are configured to create independent notifications. However, there may be requirements to aggregate multiple traps into a single notificaiton.
This article explains how can you aggregate specific traps into a single Notification in Smarts SAM?

Environment

All Supported Smarts Releases

Resolution

The following sections explain how to set up a Smarts SAM subscription to aggregate notifications for traps and how to aggregate specific traps into a single Notification in Smarts SAM.

Setting up a Smarts SAM subscription to aggregate notifications

By default, SAM does not subscribe to aggregated component notifications/events.
This can be changed by modifying the appropriate configuration file. The file used to configure aggregate notifications for traps is the ics dxa configuration file which is used to connect Smarts SAM to AMPM.
The default file name for this configuration file is dxa-conn-perf.conf. In this configuration file, the following entry is configured by default:

sub     NetworkAdapter_Performance::.*::.*/e

To configure Smarts SAM to subscribe to aggregated events, change this entry to the following:

sub     NetworkAdapter_Performance::.*::.*/ae

With this entry configured, SAM will subscribe to aggregated events. The aggregate notifications will be called Resource Exception notifications and will have a tab called Aggregates

Using the Aggregate property to aggregate notifications for specific traps

You can set up aggregate notifications for specific traps in Smarts SAM by using the Aggregate property for each trap. 

The three traps in the following example are all related to Environmental conditions on a router (VoltageWarningTemperatureWarning, and FanWarning). 
Each of the trap definitions have been changed to include the Aggregate property. If any of these traps are received, the notification will have the EventName of DegradedEnv
If the same system sends other environmental traps below, they will be added to the Aggregates tab of the DegradedEnv notification.

Following changes are highlighted that are to be added in the <Base-Dir>/local/conf/icoi/trap_mgr.conf file
