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:

"It provides us complete visibility into both company networks with one tool, which we didn't have."
