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

"The solution's most valuable features are its integration with Broadcom tools and scalability."
"I can use it to detect whenever things go wrong on my network."
"We can plan changes and replacement of end-of-life products in our environment very well because it's very accurate."
"Generally, I would recommend DX Spectrum because, despite its pricing issue, it is a valuable solution."
"​Stability has been good. We really have not had any issues.​"
"The most valuable feature is automatic discovery."
"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 does correlation so instead of producing 20 alarms if a site goes down, it only creates one."
"Topology creation is the most valuable feature."
"A good enterprise-level solution."
"The platform has good stability."
"It is a scalable product."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"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."
"It's quite a mature solution."
"The best feature is the solution's entire credibility with all vendors."
 

Cons

"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 biggest issue is our integration right now between UIM and Spectrum is lacking."
"We have a lot of different monitoring tools in the background, so orchestration has been a little bit of a challenge."
"The Spectrum OneClick is a Java-based client, and that's aging. Really, before any new feature integration, I'd love to see a comprehensive rebuild of the UI."
"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."
"The platform is complicated to use."
"Huawei devices are not properly supported, and there are incompatibility issues related to certain protocols."
"The upgrade process could be smoother. More of the steps around upgrading could be automated."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Only to improve the GUI."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"Right now, we have open tickets and they are not closing as expected."
"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."
"The main issue with OpenText Network Node Manager is not its scalability but its network topology capability limitations, while installation and deployment types are supported across various platforms."
"They should add AI options in the product's next release."
 

Pricing and Cost Advice

"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."
"Currently, a perpetual license but some services are moving to a subscription"
"The price is very high."
"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."
"It’s a great tool, but an expensive one. Learn how to use it properly."
"It is expensive compared to other tools in the market."
