Vetted Review
Overall Satisfaction with HP Network Node Manager
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.
- 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.
- 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.
- HP NNM is very good at producing root cause analysis. MTTR is reduced with NNM.
