For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.

Featured Reviews

Emmanuel Appiah Boateng - PeerSpot reviewer
Network and Security Engineer at a educational organization with 1,001-5,000 employees
Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
Vivek Jaiswal - PeerSpot reviewer
Manager IT at a manufacturing company with 1,001-5,000 employees
Central monitoring has improved outage alerts and now needs smarter detection and modern dashboards
Regarding the automated network topology and mapping feature in SolarWinds NPM, I am not satisfied with it. For static monitoring, it is acceptable. However, if it is possible, I would need a feature in SolarWinds in the future for some kind of malfunctioning detection, such as malware attacks or that type of environment. We did not have any facility to detect that in SolarWinds. I think it would be better to incorporate those types of features. Regarding customization options in SolarWinds, the ability to customize the dashboard has room for improvement. The dashboard is quite old, and we need some improvement in it. Nowadays, we have multiple tools with AI-based monitoring and web-based dashboards. SolarWinds also has a web-based dashboard, but I think there is scope for improvement in the UI. There may be other areas I would like to improve in SolarWinds NPM.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
