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

"The alarm and root cause analysis features are the most valuable to me, as they help to pinpoint causes of outages and performance issues and identify the specific component responsible for an issue, thus accelerating problem and issue resolution."
"It has a highly scalable architecture that is designed to ensure accommodation of the growing network setup for our client."
"They are very good; I open up a case and hear back from them the same day, they are very knowledgeable and helpful, and if I do not have time to research something and need it fixed, I just tell them and they take care of it, even connecting remotely to do it themselves sometimes."
"It allows us to manage alerts, schedule downtime and maintenance, as well as triage documentation for our support teams."
"The great aspect about the CA Spectrum tool is not what it does, but the integration that it provides with the other CA monitoring tools, such as CA APM."
"​It covers a lot of different types of hardware. It can do a lot and saves us time.​"
"It is the perfect monitoring solution for customers' devices."
"The network mapping functionality."
"It's a good one."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"A good enterprise-level solution."
"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."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It is a scalable product."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"Effectively monitor networks physical and virtual devices."
 

Cons

"I would like to see improvement in the ability of the user to configure the maintenance mode more efficiently."
"I think the management or configuration of devices needs some improvement."
"While deploying the tool, there were space and storage issues since the application loads for a long period each time there is an update."
"It needs better integration with other CA products."
"Reporting and network bandwidth monitoring features need to be improved."
"I would recommend AI capability built-in so it becomes more predictable and we jump ahead of the curve. This is the one really important feature I would really like to see in any product that provides alarms."
"There were some issues with deployment."
"Integration with some other tools, and integration with some Network Packet Broker, need some improvement."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"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."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."
"I would say that they definitely need to improve their support features — this is a problem. When I open a ticket, usually they respond very late."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"Only to improve the GUI."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"The cost is high comparing to its competitors, but the results are awesome."
 

Pricing and Cost Advice

"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."
"Currently, a perpetual license but some services are moving to a subscription"
"The price is very high."
"It is expensive compared to other tools in the market."
"The product, support, and maintenance are all expensive, which is another reason that we are switching to another solution."
"The price of the solution is reasonable."
"In general, the license cost will be about 30% of the total TCO for this tool (hardware/support team, OS costs, and OS management)."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
"The solution is quite expensive."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
