Functions of a NOC Responsible for monitoring the network for alarms or adverse conditions (e.g. power failures, link failure) NOC staff analyze problems, troubleshooting, collaborate with other technicians on site. NOC tracks issues/problems until they are resolved. Problems not solved within a specified time frame can be escalated to the appropriate personnel. Standard Operating Procedures exists that detail how to remedy issues/problems. Manajemen Jaringan, Sukiswo ST, MT

Nagios an enterprise-class network and server monitoring system. Useful for: Monitoring of network services. Monitoring of host resources (processor load, disk usage, system logs) Contact notifications when service or host problems occur and get resolved (via , SMS). You can define event handlers that execute when triggered by certain events. (Proactive problem resolution) Manajemen Jaringan, Sukiswo ST, MT

OpenNMS Functionalities High performance A single instance of OpenNMS supports monitoring of a large number of nodes. Automation OpenNMS minimizes the amount of manual configuration. Rule-based configuration Flexible rules can be used to specify what services are polled on what devices. ENMS also discovers and maps the physical and logical connections between these devices Layer 2 discovery, including Ethernet switches, interconnecting links, switch communities, VLANs, and VLAN membership Layer 3 discovery of network elements and interconnecting links Layer discovery of Ethernet Routing Switch 8600 WSM network elements and interconnecting links End node discovery of devices such as servers and workstations attached to the network, including Communication Server 1000 IP telephony devices Manajemen Jaringan, Sukiswo ST, MT
