Old but Stable Monitoring Solution

Rating: 8 out of 10

Incentivized

May 3, 2021

Use Cases and Deployment Scope

We are using [Micro Focus Network Node Manager i (formerly HP Network Node Manager)] [over the] last 6 years when it was HP's product and the primary purpose of Network Node Manager was to monitor our customer's network infrastructure fault and performance monitoring and reporting. It was being used by network practice and support department and monitoring team as well.

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

Likelihood to Recommend

[Micro Focus Network Node Manager i (formerly HP Network Node Manager)] is like you implement it, setup monitoring and alerting and forget it forever until any major activity is there and that is possible because of the product's stability. Another reason for product stability is less features as compared to other vendor tools and its own inbuilt database.

April 30, 2021

Use Cases and Deployment Scope

Micro Focus Network Node Manager i is being used by our end customers for their Network infrastructure monitoring such as routers, switches, loadbalancers, firewalls. There are some appliances also which are being monitored by Network Node Manager using SNMP protocol. This product is being used by the network team to keep an eye on their entire organization network fault and performance monitoring.

Pros

Network Fault and Performance Monitoring
Fault Tolerant
Distributed Architecture
Stability in operations

Cons

More out of the box monitoring parameters features
Improved GUI
Independent reporting functionality within NNMi

Likelihood to Recommend

Micro Focus Network Node Manager i is well suited when it comes to full fledged Network infrastructure monitoring using standard protocols such as ICMP, SNMP. NNMi can handle a good amount of devices load in a single server hence I prefer this tool very much as compared to other vendor tools in the market.
There are some improvement areas such as more out of the box parameters, GUI experience etc.

NNMi: An ok product with absolutely terrible support.

Rating: 4 out of 10

Incentivized

February 14, 2020

Use Cases and Deployment Scope

We use NNMi to monitor our entire network of 8,000 nodes. We create automatic tickets to SM based on some specific alarms detected by the software. Our NetOps group uses the tool along with our network operations center. We use it as a troubleshooting tool and also as a capacity and performance planning tool.

Pros

Network infrastructure monitoring.
Interface monitoring.

Cons

Flow monitoring.
QoS.

Likelihood to Recommend

Support at Micro Focus is just plain and simple terrible. The tool is fairly hard to configure and upgrades are long and arduous which makes product upgrade a nightmare. Although the documentation can sometimes claim that the product does something specific, you might discover that it is very limited in what it can actually do. An example of that is QoS for which not a lot of usual flows are supported.

HP NNM implementation from the real world perspective

Rating: 9 out of 10

Incentivized

April 17, 2017

Use Cases and Deployment Scope

We use HP NNM in production, demo, QA and DEV environments. We are an HP partner and reseller of HP NNM. HP NNM has the ability to give root cause analysis of network issues across the enterprise. It also has the ability to report on current network performance and trending data. The architecture of the product is simplified allowing the customer to implement only the items they need.

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.

Likelihood to Recommend

A less appropriate scenario is small networks. 50 devices or less. HP NNM is a world class enterprise network fault monitoring solution. Any organization with less than 50 network devices to monitor would find HP NNM is too expensive and too feature rich for their needs. Generally we find smaller organizations just need up/down monitoring. NNMi does MUCH more than that.

Any organization with 100 or more network nodes would find NNMi to be a valuable solution for their network monitoring needs.

NNMi - Enterprise Grade Network Monitoring.

Rating: 8 out of 10

Incentivized

September 8, 2025

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.

Likelihood to Recommend

Well-suited for large-scale deployment without needing more servers. Linux installation is quite stable, and Polling of a large number of devices is well managed. Less suited to Network Observability scenarios or cloud network monitoring.
