Comprehensive device monitoring enhances operational efficiency
DX Spectrum should have an automatic ticketing mechanism with ServiceNow. I need to use other tools for event management. It has a dashboarding mechanism and monitors devices and network switches through SNMP without an agent, which is good, but it should also have event management. Its LDAP authentication is fine. However, event management is not available, which is a concern. Not much else. If they can add event management, it would help. The event management should have more deduplication and alert correlation and check the bidirectional communication with ServiceNow. If a previous ticket is open and the same alert is generated, there's no need to create another ticket; updating the work notes would suffice. It should help reduce noise in alerting.

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 helps our NetOps group actually handle alarms in a way that lets them see the bigger picture of those alarms, and how they might affect our services. It helps us communicate information about the network state better to services that might be impacted by a specific network condition."
"The product’s stability and robustness are valuable."
"Generally, I would recommend DX Spectrum because, despite its pricing issue, it is a valuable solution."
"What I like best is the configuration management functionality."
"Scalable and stable network monitoring tool with a simple setup."
"The granular access control that it provided so that you could only see devices that were related to what you were working on was great. I couldn't see the entire inventory of devices. I could only see the ones that were related to my work. It has got a very granular access control component."
"The Global Collections are what I found to be most valuable. With the Global Collections, you're able to organize and categorize devices into "folders," or functional groups and categories, so that it doesn't matter which SpectroSERVER those devices are on."
"It is very stable. We have not had any major issues in over 10 years."
"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 is a scalable product."
"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."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"The platform has good stability."
"Topology creation is the most valuable feature."
"You can utilize the main file from various vendors for integration."
 

Cons

"It's not a great performance management tool. Its reporting capabilities are not very good at all."
"There should be better integration with other Broadcom products, like network performance manager. Currently, for every part of a product, you need a separate server environment. You have something for Spectrum, you have something for network performance, and you have something for NetFlow. There are a lot of islands and server farms with different technologies. They should be redeveloped to get one platform for all."
"The solution could improve by allowing the ability to monitor the network shortly after installing the software and adding an auto-discovery function."
"The visual is a little archaic."
"DX Spectrum should have an automatic ticketing mechanism with ServiceNow. I need to use other tools for event management."
"A better integration with the UIM, as far as being able to do root cause analysis and that type of analytics."
"The product should provide performance management features."
"There's a little bit of complexity to the initial install because you're dealing with operating systems. You have to make sure all the prerequisites are done, anti-virus exceptions, etc. Then there's the bringing it up and then there's discovery of the network and setting that up. It takes time."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"The solution should integrate with NAC servers."
"The deployment architecture and installation part needs improvement."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"We had some issues with some of the features, some modules are not meeting expectations."
"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."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
 

Pricing and Cost Advice

"DX Spectrum's pricing depends on the license number. It is affordable."
"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."
"DX Spectrum's pricing is neither expensive nor cheap."
"The product, support, and maintenance are all expensive, which is another reason that we are switching to another solution."
"Currently, a perpetual license but some services are moving to a subscription"
"It is expensive compared to other tools in the market."
"The solution's pricing could be better."
"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 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."
