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 performance manager is very good."
"The main thing is obviously notifications about alerts, getting ahead of the curve to make sure that we do not have system going down, or if it is down we get to know it earlier."
"With Spectrum, you have a complete insight into your entire infrastructure."
"We see an ROI in the operational cost, as we have a lot of automation behind the events coming in, and the operators get a very key understanding of what's happening, so our operations people are much faster in reacting to and solving problems."
"The initial setup is very easy; after 10 minutes, you have a complete Spectrum up and running and you can start discovery immediately."
"Implemented with Enterprise Customers across region, it is a very strong fault management tool with extraordinary correlation and alarming."
"The ability to monitor your WAN and LAN infrastructure in a simple GUI."
"The support we have been receiving has been really good."
"Effectively monitor networks physical and virtual devices."
"It's quite a mature solution."
"Overall, the tool helps maintain the health of the network."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"It's a good one."
"The platform has good stability."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
 

Cons

"There are a very few occasions when the system "barfs" and it looks like your infrastructure has gone dark, but it bounces back quickly (the system)."
"DX Spectrum should have an automatic ticketing mechanism with ServiceNow. I need to use other tools for event management."
"The price is high enough to expect an ideal solution."
"It's not the best product for availability and outages reporting."
"New areas (NFV, SDN, APM) are covered by new technologies. As such, products should have tight integration with modern data science platforms."
"It doesn't really allow for multi-tenancy. If you're an ISP or an MSP and you want to use this tool to provide these types of fault management services to your customers, you would need a separate SpectroSERVER for each customer..."
"The upgrade process could be smoother. More of the steps around upgrading could be automated."
"Support from Broadcom could be better. Sometimes we wait a very long time for a solution to level three problems."
"The cost is high comparing to its competitors, but the results are awesome."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"It is hindering us so much because we cannot give it directly to customers because after a number of connections, the system goes down within one minute."
"It needs better management for the routing protocol, which right now is really not very good."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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."
 

Pricing and Cost Advice

"Spectrum is expensive."
"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."
"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."
"It is expensive compared to other tools in the market."
"The price is very high."
"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."
"It’s a great tool, but an expensive one. Learn how to use it properly."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
"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."
