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

"It's a good tool; it's simple to do the configuration and has good discovery and integration."
"It will aid in troubleshooting and daily operations, and is invaluable in fault resolution."
"With the implementation of the shallow water approach, we've been able to significantly cut down on the number and duration of outages and the number of severities in all the categories."
"It allows us to manage alerts, schedule downtime and maintenance, as well as triage documentation for our support teams."
"Overall it is a good tool."
"Technical support is the best in class."
"Generally, I would recommend DX Spectrum because, despite its pricing issue, it is a valuable solution."
"With CA Spectrum, we are now able to monitor more proactively network assets, reduce the total downtime of these and prevent money from being lost for device stoppages."
"It is a scalable product."
"The best feature is the solution's entire credibility with all vendors."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"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."
"We need fault, availability, performance, and security."
"It is stable for fault and availability."
"A good enterprise-level solution."
"Scalability is actually one of the reasons why we picked Node Manager."
 

Cons

"It's not a great performance management tool. Its reporting capabilities are not very good at all."
"HTML5. Right now, it is a very Java driven application. We have lots of issues."
"It does crash sometimes."
"Only if the server that hosts the application is restarted without bringing down Spectrum. If this occurs it corrupts the database and has to be restored from the backup."
"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."
"What I additionally would like to see is utilization information."
"Sometimes the front-line people need to push it up to the second-level quicker."
"If nobody else has said the documentation needs improvement, let's go there. I understand, you can either write about it or you can do it. And most of us would rather they do it, but now that they've done it, those of us that didn't do it, we need to go and find: "Where did they write about this to tell us how to do it?" That's always lacking."
"We had some issues with some of the features, some modules are not meeting expectations."
"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."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"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."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."
 

Pricing and Cost Advice

"The price of the solution is reasonable."
"Currently, a perpetual license but some services are moving to a subscription"
"Spectrum is expensive."
"It is very pricey. With the current trend of enterprises moving towards cheaper and more modern looking solutions like ManageEngine, SevOne, ServicePilot, and Paesller."
"The solution's pricing could be better."
"The price is very high."
"DX Spectrum's pricing is neither expensive nor cheap."
"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."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
"The solution is quite expensive."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
