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

"This is a very good, refined product that, in the fault-tolerant configuration, approaches being bulletproof."
"CA Spectrum is awesome for networks, but when paired with CA UIM, you can have everything: datacenter, networks, virtualization and on."
"The most valuable feature is automatic discovery."
"This tool makes it more transparent to the customers, and they can be alerted and be proactive based on the data we are getting."
"I must say, CA is an excellent company and their client always comes first."
"CA Spectrum enables us to have an overall view of the state of our network."
"Out of all of the CA products that we use, I would say this is the most stable."
"Spectrum is great for root cause analysis. It has excellent correlation event management. Spectrum's stability and scalability are also amazing."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"We need fault, availability, performance, and security."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
"The HPE suite is amazingly beautiful, has a fantastic user experience, and provides a high amount of simplification across transactions when adopting cloud technologies significantly."
"The most important benefit is to have one controller and to get all information to a single point."
"A good enterprise-level solution."
"Overall, the tool helps maintain the health of the network."
"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."
 

Cons

"I would like to see better scalability, and maybe, a more intuitive user interface. ​"
"The technical support is average. We've had better support from other companies and also worse support from other companies."
"I think the interface needs a bit of a revamp. They need to adapt it to the new app world that it is now ruling (iOS, Android Apps), and it needs to offer more."
"From the users perspective the looks and feel of dashboards of Spectrum would be easier to use and for understanding as APM will be in 10.5 version which we saw in CA World."
"The report area is very poor and we cannot work properly with additional information and the custom reports."
"The Spectrum OneClick is a Java-based client, and that's aging."
"Sometimes the front-line people need to push it up to the second-level quicker."
"Technical support for this product is not so good. It's also not as good as it used to be."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"Customer service is not good compared to IBM or Zenoss support."
"Only to improve the GUI."
"It needs better management for the routing protocol, which right now is really not very good."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"The deployment architecture and installation part needs improvement."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
 

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 is neither expensive nor cheap."
"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."
"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."
"Currently, a perpetual license but some services are moving to a subscription"
"The solution's pricing could be better."
"It's an expensive solution."
"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."
"The solution is priced mid-range compared to the competition."
