ManageEngine OpManager serves as an advanced solution for monitoring network bandwidth, offering IT teams comprehensive insights into traffic behaviors and bandwidth consumption throughout the network. By utilizing flow technologies like NetFlow, sFlow, J-Flow, and IPFIX, OpManager collects detailed traffic data to pinpoint leading talkers, applications, protocols, and interactions that are utilizing bandwidth. This capability enables administrators to identify network bottlenecks, unexpected surges, and possible misuse, facilitating strategic capacity planning and expedited troubleshooting. With user-friendly dashboards, real-time traffic visualizations, and configurable alerts, OpManager equips organizations to optimize bandwidth efficiency, improve network performance, and maintain seamless service delivery.

NetCrunch is a next-gen, agentless infrastructure and traffic network monitoring system designed for hybrid, multi-site, and fast changing infrastructures. It combines real-time observability with alert automation and intelligent escalation to eliminate the overhead and limitations of legacy tools like PRTG or SolarWinds. NetCrunch supports agentless monitoring of thousands of nodes from a single server-covering physical devices, virtual machines, servers, traffic flows, cloud services (AWS, Azure, GCP), SNMP, syslogs, Windows Events, IoT, telemetry, and more. Unlike sensor-based tools, NetCrunch uses node-based licensing and policy-driven configuration to streamline monitoring, reduce costs, and eliminate sensor micromanagement. 670+ built-in monitoring packs apply instantly based on device type, ensuring consistency across the network. NetCrunch delivers real-time, dynamic maps and dashboards that update without manual refreshes, giving users immediate visibility into issues and performance. Its smart alerting engine features root cause correlation, suppression, predictive triggers, and over 40 response actions including scripts, API calls, notifications, and integrations with Jira, Teams, Slack, Amazon SNS, MQTT, PagerDuty, and more. Its powerful REST API makes NetCrunch perfect for flow automation, including integration with asset management, production/IoT/operations monitoring and other IT systems with ease. Whether replacing an aging platform or modernizing enterprise observability, NetCrunch offers full-stack coverage with unmatched flexibility. Fast to deploy, simple to manage, and built to scale-NetCrunch is the smarter, faster, and future-ready monitoring system. Designed for on-prem (including air-gapped), cloud self-hosted or hybrid networks.

NetFlow Analyzer provides real-time visibility to network bandwidth performance and leverages flow technologies. NetFlow Analyzer provides a comprehensive view of your network bandwidth usage and traffic patterns. It has been used to optimize thousands of networks worldwide. NetFlow Analyzer provides a single solution that analyzes, reports, and collects data about your network's bandwidth usage. NetFlow Analyzer can help you optimize bandwidth usage across more than a million interfaces worldwide. It also provides network forensics, network traffic analysis, and network forensics. To gain control over the most used applications, you can reconfigure policies using traffic shaping via ACLs and class-based policies. NetFlow Analyzer uses Cisco NBAR technology to provide deep visibility into Layer 7 traffic. It can also identify applications that use dynamic port numbers, or hide behind known ports.

Prevent outages with a comprehensive network monitoring solution that spans from the edge of your network to the cloud. Identify emerging problems prior to users bringing them to your attention. Accelerate troubleshooting efforts with an interactive topology map that illustrates both connectivity and dependencies. Instantly check the status of your systems, whether they are in the cloud or on-premises, to know what is operational and what is not. Achieve full visibility into the health of network devices, applications, and systems. Utilize topology-aware monitoring that comprehends network dependencies, resulting in fewer but more insightful alerts. Receive updates through various channels, such as SMS, email, web, or Slack, to stay informed about issues before they impact users. Seamlessly integrate your existing systems with a robust REST API to streamline your operations. Visualize network devices, servers, virtual machines, and wireless environments within context. Click on any device for immediate access to a comprehensive array of monitoring settings and reports, allowing you to see the interconnectedness of your infrastructure and find solutions more efficiently. This proactive approach not only enhances performance but also minimizes the risk of unexpected downtimes.
