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

"Clear picture of all network and server pictures Centralized console to manage network and systems All backup for router configurations"
"Scalability is a highly rated feature of this solution. It is better than some of the other tools that I've used in terms of scalability. We scaled it to tens of thousands of devices."
"​The stability of the product is key. It never breaks, really. The stability and reliability of the Spectrum product have been top-notch.​"
"It does correlation so instead of producing 20 alarms if a site goes down, it only creates one."
"Spectrum allows us to have a holistic view of our network architecture."
"It's easy to implement, very configurable, and you can easily add new alerts and watch lists so we can certify new devices and watch the behavior of these new devices out of the box."
"An organization using DX Spectrum is more easily able to understand the root cause when something happens in its environment."
"I must say, CA is an excellent company and their client always comes first."
"Scalability is actually one of the reasons why we picked Node Manager."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"We need fault, availability, performance, and security."
"It's quite a mature solution."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
 

Cons

"It's really tough to say because it really does have a lot to do with how much time you put into it."
"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."
"When we have a high capacity of traffic, we have problems with the stability of the system."
"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 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)."
"The solution could improve by allowing the ability to monitor the network shortly after installing the software and adding an auto-discovery function."
"What I additionally would like to see is utilization information."
"OS monitoring needs to be better developed, as well as their services, e.g., cluster monitoring, URLs, etc."
"The setup was complex and needs a medium kind of knowledge. The documentation is also not very good, i.e., a lot of things that are not written in the document are surprises."
"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."
"As the technologies evolve, also these solutions or the monitoring tools should evolve to cover the progress in technology, including capabilities related to monitoring of virtualized devices today, as the DNS is on the table in this way."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The deployment architecture and installation part needs improvement."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"We had some issues with some of the features, some modules are not meeting expectations."
 

Pricing and Cost Advice

"It is expensive compared to other tools in the market."
"Spectrum is expensive."
"Currently, a perpetual license but some services are moving to a subscription"
"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."
"The price of the solution is reasonable."
"The solution's pricing could be better."
"The price is very high."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
"The solution is quite expensive."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
