Network Device Monitoring

Your network monitoring software should be able to provide insights into the availability quotients of all devices in the network.

The foundation of your network monitoring strategy

Network device monitoring is critical to device availability – the simple probability that the device is available, up and running. And since any device, regardless of ruggedness, can fail, availability is defined as an average between the time the device is down, and the time taken to get it repaired and running again. Device availability is almost synonymous with network uptime, and reduced availability in one device can clog the entire traffic – one single component that is down or under-performing can cause bottlenecks that slow down entire networks.

Your network monitoring software should be able to provide insights into the availability quotients of all devices in the network, based on availability metrics including: device status, time to respond and downtimes – regardless of manufactures and vendors. Physical and virtual user nodes, wireless hardware, routers, switches, firewalls, and business-critical applications should have an assured level of availability. WAN links too should be monitored for availability, both for connection issues and related network failures, as well as for SLAs.

Network device monitoring software makes use of ICMP pings and SNMP messages to ensure each device is regularly contacted. Alerting and reporting are necessary features to look for here, since a network management system that can identify device failure and alert you almost immediately will result in lower downtimes, and reporting and access to historical data information will help you troubleshoot faster. In addition, you should look for a single point of control for network gear, systems and applications to simplify monitoring.

Ipswitch WhatsUp Gold offers network device monitoring services combined with server and application monitoring to help you avoid downtime and find and fix problems faster. For example, its active monitors use SNMP v1-3, SSHv2 and WMI protocols to monitor network devices and servers for availability (SNMP for Linux/Unix, and WMI for Windows systems). Passive monitors identify availability issues in near-time by analyzing SNMP traps and log messages. Reports and alerts play an important part in availability management. WhatsUp Gold's Alert Center – with its configurable thresholds, escalating alert polices, and alert acknowledgements that pin down issue ownership – ensures business-critical applications and devices are fault-monitored and are made available 24/7. Additionally, with instant access to over 200 pre-loaded reports and custom dashboard views, network managers can easily navigate real-time graphs and historical data, to quickly troubleshoot problems and lower mean time to resolution.
