Distributed Event Interception: Benefits
Reduced Network Traffic and Management Server Workload
through VPO-Specific Features for Local Processing
– More attributes to suppress messages (e.g. SNMP Trap
Variables)
– Duplicate message suppression, local actions etc.
– Event Correlation Services
Secure Communication between Agent and Management Server
through DCE/RPC-Based Implementation
– Authentication, Encryption
Flexible Management through VPO Flexible Manager Concepts
– Follow-the-Sun, Competence Centers, Backup Manager

Distributed Event Interception:
Configuration
Supported Platforms:
– all Platforms, where NNM is supported
– Novell NetWare 4.1, 4.11, 5.0, 5.1 with NMA 2.1 installed
Configuration Steps:
– Configure Event Interception Template in Message Source Templates
window and in Add SNMP Trap window.
– Assign Event Interception Template to agents and distribute the
templates.
– If NNM is not to be used on agent for event interception (i.e. SNMP
traps intercepted directly by opctrapi), then add the following line to
file opcinfo:
SNMP_SESSION_MODE
NO_TRAPD
– Restart the VPO agents

How to Avoid Duplicate Messages
Problem Situation:
Node pepper
SNMP Destinations:
• curry
• nutmeg

VPO Management Server
Solution with VPO:
• SNMP Agents must have only one trap destination configured
• An VPO event interceptor runs on all possible SNMP destinations
