RamPrakash Ramar - PeerSpot reviewer
Monitor broadcast systems effectively with real-time data processing and insightful feedback
The solution will monitor data in real-time and can scale out well. For instance, in a television studio, I might deal with about three hundred pieces of equipment. However, in other sites, it can handle 200 to 2500 nodes that send data every second. The system efficiently processes and analyzes data to provide insightful feedback, such as pinpointing specific equipment errors. It also offers predictive analytics based on received data, rather than just storing it.
Ahmed-Salman - PeerSpot reviewer
Reliable network monitoring and proactive analytics enhance decision-making with areas for configuration improvement
NNMi is an OpenText product and serves as the OpenText Network Node Manager monitoring tool. OpenText Network Node Manager is used for network monitoring of switches, routers, firewalls, load balancers, and all network devices. It can support any SNMP protocol. The advantages of OpenText Network Node Manager stand out because it can build the topology, Layer 2 topology, and Layer 3 automatically once devices are added, connecting them together, such as device one, for interface one, connected with interface one on another device. The integration capability of OpenText Network Node Manager is excellent because it integrates directly, and I can configure the integration to feed the CMDB, from where I can get all information from network monitoring into the CMDB, linking it with the infrastructure and correlating events. I use advanced fault monitoring and management features in OpenText Network Node Manager for topology and fault monitoring, as it can alert or generate an event if the value exceeds or falls below a predefined threshold for SNMP traps. The predictive analytics impact planning and optimization strategies because the product can be linked with another product for analytic analysis, allowing me to see the interface utilization trend and proactively take action if the utilization increases. The automated network discovery features and topology mapping in OpenText Network Node Manager have a positive impact. It supports a bundle with another product for NetFlow to monitor traffic, ports, protocols, and SLAs, and I can build compliance reports to address security vulnerabilities, such as identifying all devices using outdated protocols.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is user-friendly and is readily customizable, which allows us to do control and monitoring in a single stage."
"Data Miner allows you to take control. It has an API to talk to different products, including drivers to talk to the APIs of third-party products. You can control it from the screen."
"The most valuable feature of DataMiner is its comprehensiveness. It provides an open driver that allows you to customize and program each aspect of the system. Additionally, there are many separate modules available that can be used to enhance the system's capabilities beyond just monitoring, allowing you to manage your entire workflow. This is a valuable feature that makes troubleshooting easier and helps to optimize the use of the system."
"The solution will monitor data in real-time and can scale out well."
"Overall, the tool helps maintain the health of the network."
"You can utilize the main file from various vendors for integration."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"Topology creation is the most valuable feature."
"A good enterprise-level solution."
"It's quite a mature solution."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"We do not have any issues stability-wise."
 

Cons

"I am looking forward to the company continuing to improve its solution and incorporate new technologies. Specifically, I hope that they will allow their cloud database environment to host services, rather than requiring the use of on-premises digital or physical servers. The company is moving in this direction, but I am still waiting for this capability to be implemented."
"The system's complexity during installation could be reduced."
"We would like to have more products supported by the drivers because there are so many products out there. If DataMiner has not built the drivers to support them we can not control them, we can only see them based on SNMP. If more drivers are included, it won't cost us if we have new products."
"As the technologies evolve, also these solutions or the monitoring tools should evolve to cover the progress in technology, including capabilities related to monitoring of virtualized devices today, as the DNS is on the table in this way."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"The way the solution currently works means I'm not able to customize my own reports."
"The solution should integrate with NAC servers."
"They should add AI options in the product's next release."
"The main issue with OpenText Network Node Manager is not its scalability but its network topology capability limitations, while installation and deployment types are supported across various platforms."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
 

Pricing and Cost Advice

"DataMiner is an expensive solution and that is why many companies do not use it. Other solutions are less expensive."
"It's an expensive solution."
"The solution is quite expensive."
"It is more inexpensive than other products in the market."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is priced mid-range compared to the competition."
