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 Message Source Configuration: SNMP Trap Interception
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 Message Source Configuration: SNMP Trap Interception
