Tools: Nagios • Nagios is used for network and system state monitoring. • The Global NOC has developed numerous Nagios plug-ins for monitoring its managed networks, including a TL1 plug-in to monitor NLR 15808 and 15454 equipment. check_cpu SNMP check of CPU load on a Juniper or Cisco device check_bgp SNMP check of BGP session status check_isis SNMP check of ISIS adjacency check_ospf SNMP check of OSPF status from the OSPF neighbor table check_pim SNMP check of OSPF status of a PIM neighbor check_msdp SNMP check of the status of a MSDP peering session check_intf SNMP check of the status of an interface (indexed by IP) check_intf_by_ifname SNMP check of the status of an interface (indexed by ifName)
Tools: AlertMon • The AlertMon front-end to monitoring systems consolidates alerts from network monitoring systems, provides an alert management interface, and links to ticketing and documentation for alerted elements. AlertMon receives input from Nagios and is being extended with interfaces to other monitoring systems.
Tools: Global NOC Database • The Global NOC Database containscomprehensive information regarding network elements, operations and problem management information for elements, network topology, and contacts. • Drill down linkages to the Database information is being developed for front-end tools such as AlertMon. • The Database is currently implemented for the NLR network and will be extended to all Global NOC-managed networks, and will become the primary information tool for the NOC.
Tools: Footprints • The ticketing system – used for problems, changes, installation, maintenance, and other tracking.
Tools: TickMon • TickMon is front-end to the ticketing system that provides a consolidated view of open and active tickets.
Tools: Animated Traffic/Usage Maps • Presents a geographic and/or topologic-based view of network use and error data. Data collected via SNAPP SNMP collector.
Tools: MRTG, RRDTool, Cricket • Used to gather and graph time series data, e.g. link utilization and errors.
Tools: BSCW • Basic Support for Cooperative Work (BSCW) is used for documentation repository.
Tools: Router Proxy • The Router Proxy acts as an interface by whicha user can get information from 'show' commands on a router using a web interface. The user enters a query to the router through a HTML form. This query is sent to the router, and the results are presented to the user in their web browser.
