Use Cases and Deployment Scope

We use NNMi to monitor the complete Network infrastructure. more than 80K devices . NNMi automatically discovers devices and network topology, creating a comprehensive view of the network architecture. Fault Monitoring:It detects, monitors, consolidates, and correlates network faults to help pinpoint issues. Performance Monitoring:NNMi provides detailed performance data reports to ensure networks run smoothly. Alerting & Incident Management:The system generates real-time alerts for important events and incidents, which can be customized to provide diagnostic tips. T opology Visualization:Users can visualize network connectivity and relationships to better understand and diagnose problems.

Pros

  • Network Discovery.
  • Fault Monitoring.
  • Alerting & Incident Management.
  • L2 discovery.
  • Topology Visualization.
  • Enterprise level large scale monitoring.
  • Performance reporting using iSPI.

Cons

  • Layer 2 connection discovery is not always correct.
  • Enterprise to Cloud network visibility.
  • Reporting feature can be embedded to the tool itself than installing another product.

Return on Investment

  • Centralized fault and performance monitoring for large scale infra.
  • Improved Network Availability for on-prem devices.
  • NNMi supports massive network environments with support for thousands of devices from hundreds of vendors, ensuring it can grow with your business needs.
  • Some of the negatives are : Limited Reporting.
  • Potential Integration Issues: integration between NNMi and OpenText Network Automation (NA), where discovered nodes are not consistently synced. and also a wide variety of integration methods are available to integrate with the latest tools in the market.
  • Installation Complexities:
  • There are issues with installations, including post-installation configuration failures, and challenges confirming that the correct encryption algorithms are being used during setup.

Pros

  • Fault and Performance Monitoring
  • Performance Reporting
  • Alerting and Flexible threhsolds
  • Product stability

Cons

  • Micro Focus still using older technology
  • Unavailability of APIs for 3rd party interaction
  • no out of the box integrations with 3rd party systems

Most Important Features

  • Fault and Performance Monitoring
  • Performance Reporting via iSPI
  • Network Topology with Tenant View

Return on Investment

  • Our network SLA are under prescribed values
  • Capacity planning was possible with the help of reports availability
  • API option is still missing and hence unable to leverage PowerBI and advanced reporting tools.

HP NNM implementation from the real world perspective

Pros

  • Automated network discovery. Simple discovery rules and granular settings across regions allow the user to manage what parts of the network are automatically discovered. The user also has a choice not to use automated discovery if they do not want it. They can add lists of devices by CSV file if needed.
  • Simple polling architecture. NNM has a single polling source allowing the customer to keep simple ACL rules allowing NNM access to devices across the enterprise. It also supports a hierarchical structure with multiple instances if needed by the user.
  • Out of box content. There are multiple dashboards available out of box with the different modules that can be added onto NNM. Key Performance Graphs include Top 10 device CPU utilization, Top 10 Interfaces with Errors, Top 10 Interfaces with packet drops, Top 10 QoS violators.
  • Layer 2 and Layer 3 network mapping. NNM is very good at automatically creating network topology maps. It allows the user to group nodes together showing small parts of the topology to entire regions for trouble shooting or NOC monitoring.

Cons

  • Most customers would like to see NNM get away from using some Java applets.
  • In environments where we see more than 10 different network device vendors in production, we see issues with L2 mapping. Different vendors use different L2 protocols. This can cause an issue with L2 discovery and mapping.

Return on Investment

  • HP NNM is very good at producing root cause analysis. MTTR is reduced with NNM.
