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.
