Featured Reviews

RamPrakash Ramar - PeerSpot reviewer
Manager, Engineering at Benchmark Broadcast Systems
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
Performanc Monitoring and Application Architect at Hewlett Packard Enterprise
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

"DataMiner performs quite well because it can be customized to your requirements, to what you want to see."
"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."
"Among other NMS systems, DataMiner is considered the leader, and other NMS systems look up to DataMiner and aim to compete with it."
"The solution is user-friendly and is readily customizable, which allows us to do control and monitoring in a single stage."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"Topology creation is the most valuable feature."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"A complete solution for network monitoring."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"Most valuable function would have to the internal causal engine and its root cause analyzer which keep us updated on critical errors and incidents in our network environment."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
 

Cons

"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."
"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."
"Sometimes DataMiner is not stable, with rare memory leakage issues and other software problems."
"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."
"Only to improve the GUI."
"The cost is high comparing to its competitors, but the results are awesome."
"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."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The deployment architecture and installation part needs improvement."
"It is hindering us so much because we cannot give it directly to customers because after a number of connections, the system goes down within one minute."
"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."
 

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 priced mid-range compared to the competition."
"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 quite expensive."
