Monitoring has become centralized and management now sees real‑time health of key network assets
The time investment required is significant, not because of difficulty but because of the need for free time to invest in it. We need to get the knowledge. We know there are many options, but we took an external vendor to install and make the customization. If we want to make others changes without paying for customization, we need to learn it deeply by ourselves. The tutorials are very complicated. They could work on that area. The tutorial part could be more simplified. I know there are many explanations, and you can get help or documents in one click on the current page in the product, but it is not very clear. If you want to do something new that you did not see from the vendor in the installation, it is not very simple. The documents are good for people that know how to operate the product well, but for new users, it is not simple.

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

"It will aid in troubleshooting and daily operations, and is invaluable in fault resolution."
"The topology correlation for layers one, two, three, and four significantly reduces the number of false positives (>98% ratio)."
"It creates transparency and makes everything work by being more transparent."
"The most valuable feature is the event correlation mechanism."
"Discovery: Scheduled, on-demand, synchronized with eHealth."
"Thanks to Spectrum, we are able to monitor (and send out alarms for) our whole IT infrastructure 7/24 without having more than a minimal number of technical persons."
"Its ability to alert us on network issues before they become critical is a great benefit."
"The ability to monitor your WAN and LAN infrastructure in a simple GUI."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"A good enterprise-level solution."
"It provides very good scalability from 200 nodes to 30,000 nodes and from 2,500 interfaces to 60,000 interfaces."
"The best feature is the solution's entire credibility with all vendors."
"It's a good one."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
 

Cons

"CA Broadcom support is very bad—one of the worst."
"There should be better integration with other Broadcom products, like network performance manager. Currently, for every part of a product, you need a separate server environment. You have something for Spectrum, you have something for network performance, and you have something for NetFlow. There are a lot of islands and server farms with different technologies. They should be redeveloped to get one platform for all."
"I did not see the best level of usability."
"I'd like to have more dynamic weather map capabilities and network mapping tools."
"It was somewhat complex to implement."
"When we have a high capacity of traffic, we have problems with the stability of the system."
"For my use case, incident coordination was an area of improvement. The internal software engine for coordinating outages could use improvement because sometimes, we used to get false alerts for unrelated devices. They did a really good job of trying to make sure that you got one major alert and any of the subsequent devices downstream were just additions to that, but occasionally, the engine wouldn't properly catch the right things, and we used to get a flood of alerts."
"The Spectrum OneClick is a Java-based client, and that's aging."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"The cost is high comparing to its competitors, but the results are awesome."
"The deployment architecture and installation part needs improvement."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"It needs better management for the routing protocol, which right now is really not very good."
"That is a little bit difficult for me because I haven't been personally dealing with the software directly, so the subcontractor has been the face in informing us what the product is capable of."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
 

Pricing and Cost Advice

"The solution's pricing could be better."
"DX Spectrum's pricing depends on the license number. It is affordable."
"It’s a great tool, but an expensive one. Learn how to use it properly."
"It is very pricey. With the current trend of enterprises moving towards cheaper and more modern looking solutions like ManageEngine, SevOne, ServicePilot, and Paesller."
"Since the acquisition by Broadcom, we have not had such a good experience with licensing and pricing. Since they were bought by Broadcom, every sales contract is getting complicated. It's very complicated, and it's much more expensive than before. It's not a good pricing strategy from Broadcom."
"DX Spectrum's pricing is neither expensive nor cheap."
"The price is very high."
"The price is good enough to expect an ideal solution. It's expensive."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
"The solution is quite expensive."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
