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

"Reliability and stability are valuable because of the integration with CA Service Desk and the application of incident and event management in our environment."
"It has improved the way our organization has functioned over the last 10 years."
"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."
"The most valuable feature for us is that we can model a large variety of devices and receive SNMP traps from them."
"Definitely consider Spectrum."
"It allows us to manage alerts, schedule downtime and maintenance, as well as triage documentation for our support teams."
"​Stability has been good. We really have not had any issues.​"
"CA Spectrum allowed our client, a Tier 1 TELCO, to manage their E2E network infrastructure, proactively monitor Enterprise: GMPLS, IPVPN, ISDN, LTE and Leased Line services against set SLAs, and maintain a top quality of service, while the easy integration of topology views to a web portal provided a wow factor by exposing real-time performance and health status of enterprise infrastructure setups to customers."
"The great thing about this solution is its compatibility for enterprise level organizations; if you need to install 10,000 or even 20,000 devices, it's easy to monitor, and the product's fault management is awesome."
"The most important benefit is to have one controller and to get all information to a single point."
"Overall, the tool helps maintain the health of the network."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"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."
"It is a scalable product."
"The platform has good stability."
 

Cons

"New areas (NFV, SDN, APM) are covered by new technologies. As such, products should have tight integration with modern data science platforms."
"We have had some issues with the spec server and the high availability replication of data. It fails over well, but it does not come back very well. We get duplicated events."
"It takes some time to learn how to use this solution."
"Needs better integration with all the other products in the Agile suite of tools; anything they could do to make that less complex, would be great."
"The technical support is average. We've had better support from other companies and also worse support from other companies."
"There appears to be no intelligence within Spectrum itself, for example if we were to move a network device to a different switch port, it will see the neighbor as being available, but the link or switch port as down."
"DX Spectrum should have an automatic ticketing mechanism with ServiceNow. I need to use other tools for event management."
"I would suggest improving the web GUI to improve the device monitor configuration and to improve or to integrate the new tool for reporting."
"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 deployment architecture and installation part needs improvement."
"The technical documentation takes experience and much reading to master."
"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."
"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."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"Only to improve the GUI."
 

Pricing and Cost Advice

"It’s a great tool, but an expensive one. Learn how to use it properly."
"Spectrum is expensive."
"DX Spectrum's pricing depends on the license number. It is affordable."
"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."
"The price is very high."
"The solution's pricing could be better."
"The price is good enough to expect an ideal solution. It's expensive."
"The solution is quite expensive."
"The solution is priced mid-range compared to the competition."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It's an expensive solution."
"It is more inexpensive than other products in the market."
