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

"The solution is user-friendly and is readily customizable, which allows us to do control and monitoring in a single stage."
"The solution will monitor data in real-time and can scale out well."
"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."
"Among other NMS systems, DataMiner is considered the leader, and other NMS systems look up to DataMiner and aim to compete with it."
"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."
"DataMiner performs quite well because it can be customized to your requirements, to what you want to see."
"The best feature is the solution's entire credibility with all vendors."
"A complete solution for network monitoring."
"Overall, the tool helps maintain the health of the network."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"It is stable for fault and availability."
"We need fault, availability, performance, and security."
"A good enterprise-level solution."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
 

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."
"Sometimes DataMiner is not stable, with rare memory leakage issues and other software problems."
"We would like to have more products supported by the drivers because there are so many products out there."
"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 dashboards are not customizable and it's not user-friendly."
"The setup was complex and needs a medium kind of knowledge. The documentation is also not very good, i.e., a lot of things that are not written in the document are surprises."
"It needs better management for the routing protocol, which right now is really not very good."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"We had some issues with some of the features, some modules are not meeting expectations."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
 

Pricing and Cost Advice

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