Many businesses today, especially those operating in the IT landscape, deploy large-scale networks to meet their growing business requirements. This is why efficient network management is vital for a business to ensure continuous service delivery, maintain operational continuity, and facilitate internal and external communication.

However, technological advancements have enabled networks to evolve in unimaginable ways. Modern networks house a deluge of physical and virtual components comprised of parts from multiple vendors and are distributed over geographies, making network management a tall order for administrators.

To work around these obstacles, businesses need a robust network management system(NMS) capable of managing physical (wired and wireless), virtual, and hybrid networks. Such comprehensive network monitoring tools, network management solutions /network management systems empower network administrators and help them gain complete visibility and control over their network infrastructure. 

Challenges in the absence of a network management system (NMS)

Below are some of the most prominent roadblocks that a business faces without a network management system:

  • Fault diagnosis: Network components are susceptible to performance degradation. Without a network management system, it's difficult to diagnose network faults, which impedes troubleshooting.
  • Unforeseen downtime: Businesses can expect frequent outages and prolonged downtime without a network management system. This can adversely impact operational continuity and productivity levels. On top of this, not all businesses possess enough resources to bear the exorbitant costs of network downtime.
  • Service interruptions: Without a network management system to keep networks in check, businesses may experience disruptions in service delivery, which will make it hard to meet SLAs.
  • Security threats: Erroneous network configuration changes and poor network security can expose networks to security vulnerabilities, leading to data appropriation.

OpManager: The network management system your business needs

ManageEngine's reliable network monitoring solution - OpManager, is a comprehensive network performance monitoring system with which organizations can gain complete visibility and control over their entire IT infrastructure. Out of the box, OpManager's NMS software monitors all physical and virtual network components for performance, health, and availability. It also supports more than 53,000 vendor templates and possesses distributed monitoring capabilities.

OpManager's functions include but are not limited to:

Discovery: Hassle-free inventory and network management

OpManager, the network managemet system tool, saves you the hassle of identifying every network device manually. OpManager offers both manual and automated device discovery options. Manual addition requires you to enter the device's IP or credentials into OpManager. Automated device discovery options include specifying the IP range of devices, CIDR discovery, or uploading a CSV file with device credentials for bulk discovery. OpManger also lets you schedule the discovery process at specified intervals.

Performance: Real-time network management

Network devices are susceptible to performance degradation over time. OpManager's enterprise network management system software helps you proactively monitor all physical and virtual network components by associating performance monitors. OpManager performs system performance monitoring by relying on SNMP/WMI protocols to fetch performance data from network devices. You can either manually add appropriate performance monitors for each device or make use of OpManager's device templates, which associates a predefined set of monitors to devices on discovery
