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 is easy to navigate."
"​The stability of the product is key. It never breaks, really. The stability and reliability of the Spectrum product have been top-notch.​"
"We were able to standardize the internal processes across all internal departments, resulting in almost an elimination of non-standard process flows through our organization."
"It does correlation so instead of producing 20 alarms if a site goes down, it only creates one."
"I have found the cross analysis feature to be the most valuable."
"The monitoring just comes to us: "Oh, there's something wrong with that machine." It tells us. There are some 50,000 machines or so, all doing different things. And if they go down we hear about it."
"Spectrum is very useful for us, because the product lets us monitor and control all the various components of our infrastructure that support our business from an IT perspective."
"The Spectrum tool improved our network assurance levels for our business units."
"It is stable for fault and availability."
"You can utilize the main file from various vendors for integration."
"It's quite a mature solution."
"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."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"Topology creation is the most valuable feature."
"We do not have any issues stability-wise."
 

Cons

"DX Spectrum needs to incorporate faster support."
"The platform is complicated to use."
"The upgrade process could be smoother. More of the steps around upgrading could be automated."
"DX Spectrum needs better documentation on its complex features."
"DX Spectrum should have an automatic ticketing mechanism with ServiceNow."
"DX Spectrum should have an automatic ticketing mechanism with ServiceNow. I need to use other tools for event management."
"DX Spectrum is stable. However, now and then there are some issues, but overall it is good."
"Huawei devices are not properly supported, and there are incompatibility issues related to certain protocols."
"They should add AI options in the product's next release."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"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."
"Only to improve the GUI."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The solution should integrate with NAC servers."
"The way the solution currently works means I'm not able to customize my own reports."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
 

Pricing and Cost Advice

"Spectrum is expensive."
"The product, support, and maintenance are all expensive, which is another reason that we are switching to another solution."
"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 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 price is very high."
"Currently, a perpetual license but some services are moving to a subscription"
"The price is good enough to expect an ideal solution. It's expensive."
"DX Spectrum's pricing depends on the license number. It is affordable."
"It is more inexpensive than other products in the market."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
"The solution is quite expensive."
"I wasn't involved in the pricing, but I think it's quite expensive."
