Bandwidth Utilization

Monitoring bandwidth is one of the most critical aspects of network management and traffic monitoring software.

Monitoring bandwidth is one of the most critical aspects of network management and traffic monitoring software. Without comprehensive insight into traffic type and bandwidth utilization, it is not possible to ensure proper availability of bandwidth. By monitoring bandwidth utilization, it is possible to:

  • Determine the users, applications and hosts taking up critical bandwidth
  • Assist with identifying unauthorized applications
  • Ensure business-critical applications receive enough bandwidth

With viruses and malware often consuming out of the ordinary amounts of bandwidth, monitoring bandwidth utilization can also be invaluable in identifying security anomalies.

WhatsUp Gold provides comprehensive bandwidth utilization monitoring with detailed insight into how bandwidth is being consumed. By leveraging a variety of technologies across vendors, including Cisco NetFlow, NetFlow-Lite and NSEL, Juniper J-Flow, sFlow and IPFIX protocols, WhatsUp Gold can convert raw data from these protocols into meaningful data showing bandwidth utilization.

WhatsUp Gold uses the data from flow-enabled devices to monitor bandwidth utilization as by users, applications, protocols and connections. Real-time automatic classification of traffic according to type and protocol allows instant tracking and resolution of network congestion issues. By monitoring bandwidth, administrators can plan for spikes in usage, identify bandwidth-hogging applications and users (by IP address) and ensure business-critical applications get the requisite amount of bandwidth. Billing accounts from service providers, which are typically based on peak utilization, can be verified through 95th percentile reporting (a widely used calculation to measure regular and sustained bandwidth utilization). Validate that business-critical applications get the bandwidth allotted to them by monitoring Cisco NBAR and CBQoS.
