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 fault management is perfect."
"Scalable and stable network monitoring tool with a simple setup."
"The presentation layer is pretty simple and straightforward."
"What I like best is the configuration management functionality."
"The tool is very mature, and its valuable features are monitoring and configuration management."
"All networks (or network equipment) are monitored through CA Spectrum."
"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."
"We were able to standardize the internal processes across all internal departments, resulting in almost an elimination of non-standard process flows through our organization."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It's quite a mature solution."
"You can utilize the main file from various vendors for integration."
"A good enterprise-level solution."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"It is stable for fault and availability."
"Overall, the tool helps maintain the health of the network."
"It is a scalable product."
 

Cons

"If they could interact with the MIBs of vendors better, and have a lot more pre-loaded ones, that would be amazing for us right now."
"We have a lot of different monitoring tools in the background, so orchestration has been a little bit of a challenge."
"It takes some time to learn how to use this solution."
"I would suggest improving the web GUI to improve the device monitor configuration and to improve or to integrate the new tool for reporting."
"Huawei devices are not properly supported, and there are incompatibility issues related to certain protocols."
"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."
"From a functionality perspective, the product is not doing what it should. Also, there are some concerns about the accessibility. I would appreciate additional out-of-the-box troubleshooting scripts, like templates for addressing various issues. Currently, when troubleshooting online, I need to create my scripts. It would be beneficial if the platform could provide pre-built scripts or templates to help automate certain troubleshooting tasks."
"The biggest issue is our integration right now between UIM and Spectrum is lacking."
"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."
"Right now, we have open tickets and they are not closing as expected."
"They should add AI options in the product's next release."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"The deployment architecture and installation part needs improvement."
 

Pricing and Cost Advice

"It’s a great tool, but an expensive one. Learn how to use it properly."
"It is expensive compared to other tools in the market."
"DX Spectrum's pricing depends on the license number. It is affordable."
"The price is good enough to expect an ideal solution. It's expensive."
"The price of the solution is reasonable."
"DX Spectrum's pricing is neither expensive nor cheap."
"Spectrum is expensive."
"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."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
"The solution is quite expensive."
"It is more inexpensive than other products in the market."
