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

"If we can be proactive, we maintain maximum uptime of our network infrastructure."
"DX Spectrum uses an SNMP Trap to accept all the details, especially for device monitoring of faulty devices, allowing me to use Spectrum effectively."
"Some of the most valuable features are it's highly scalable, the carrier is great, and if something has SNMP, it can monitor it. It's a great network fault management solution."
"It has a high-quality graphical interface."
"The initial setup is very easy; after 10 minutes, you have a complete Spectrum up and running and you can start discovery immediately."
"It provides us complete visibility into both company networks with one tool, which we didn't have."
"CA Spectrum helps our organization improve network service levels, and with Spectrum’s integrated automated fault management and fault isolation features, it helped us reduce MTTR by 50% and costs as well."
"It is an excellent tool for monitoring, managing event correlation, and providing integration with other tools."
"Scalability is actually one of the reasons why we picked Node Manager."
"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."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"It's a good one."
"We do not have any issues stability-wise."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
 

Cons

"Integrations with other CA products A better way to create reports"
"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."
"SpectroSERVER and reporting databases can grow quickly if you don't keep track of trap storms; this can cause SpectroSERVER to crash and performance issues with reporting."
"The upgrade process could be smoother. More of the steps around upgrading could be automated."
"Technical support is so-so. It depends on who you get."
"We're trying to replace this solution with another product because it's too expensive and not very user-friendly; it requires training and takes some time to learn how to use it."
"Technical support for this product is not so good. It's also not as good as it used to be."
"NCM needs to be more user-friendly and refined."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"The cost is high comparing to its competitors, but the results are awesome."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Only to improve the GUI."
"The technical documentation takes experience and much reading to master."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."
"I want to have some of those nicer features for when networks go flapping. I want to receive alerts before problems occur rather than when it actually goes down."
"The way the solution currently works means I'm not able to customize my own reports."
 

Pricing and Cost Advice

"The cost of some of these products are a little cost prohibitive, which is unfortunate. We have to find lower cost solutions for some of the things that we have to pull in. For the most part, CA has capabilities in pretty much everything that you would need. You just have to figure out where are you going to spend the most money for what you have to actually get done. You can do all these things but, which ones do you have to do? And that's hard to choose sometimes because you want to do them all."
"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."
"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 price of the solution is reasonable."
"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."
"Spectrum is expensive."
"The solution's pricing could be better."
"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."
"The solution is quite expensive."
"I wasn't involved in the pricing, but I think it's quite expensive."
