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 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."
"We can plan changes and replacement of end-of-life products in our environment very well because it's very accurate."
"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."
"As the kind of enterprise that straddles the line between telco size and enterprise size, it scales for us, because we're not all the way at telco yet."
"The main thing is obviously notifications about alerts, getting ahead of the curve to make sure that we do not have system going down, or if it is down we get to know it earlier."
"DX Spectrum uses an SNMP Trap to accept all the details, especially for device monitoring of faulty devices, allowing me to use Spectrum effectively."
"The performance manager is very good."
"The fault management is perfect."
"We do not have any issues stability-wise."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It is a scalable product."
"The best feature is the solution's entire credibility with all vendors."
"It's quite a mature solution."
"It is stable for fault and availability."
"You can utilize the main file from various vendors for integration."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
 

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."
"Integration with some other tools, and integration with some Network Packet Broker, need some improvement."
"It doesn't really allow for multi-tenancy. If you're an ISP or an MSP and you want to use this tool to provide these types of fault management services to your customers, you would need a separate SpectroSERVER for each customer..."
"I think the management or configuration of devices needs some improvement."
"I would like to see CA move Spectrum, Performance Manager, and some of their other tools moved to a SaaS based model. You see a lot of other manufacturers which are moving toward SaaS based models."
"DX Spectrum could be improved by them getting rid of the Java console. It would also be better with Turkish language support."
"​I would like to see them eliminate the Java console. The user interface for this is a Java applet that runs on your desktop, and it is very problematic for us."
"We want to make our own choice for the AIOps solution and do not want to be forced to use the Broadcom OI solution by default."
"Only to improve the GUI."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"We had some issues with some of the features, some modules are not meeting expectations."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"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."
 

Pricing and Cost Advice

"The product, support, and maintenance are all expensive, which is another reason that we are switching to another solution."
"The solution's pricing could be better."
"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."
"The price of the solution is reasonable."
"Currently, a perpetual license but some services are moving to a subscription"
"In general, the license cost will be about 30% of the total TCO for this tool (hardware/support team, OS costs, and OS management)."
"The price is very high."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It's an expensive solution."
"The solution is quite expensive."
"It is more inexpensive than other products in the market."
"The solution is priced mid-range compared to the competition."
