WhatsUp Gold developed by Ipswitch (acquired by Progress Software May 2019) offers network performance monitoring and mapping. It supports core monitoring features, including automated workflows and network capacity planning, and monitors across hybrid environments.
Observium is easier to use and "prettier" than most of the other open source tools out there. It's also significantly cheaper than most of the mid-range NMS products out there, and several orders of magnitude cheaper than the big boys. It tends to be my go-to NMS for these …
[Progress WhatsUp Gold (formerly Ipswitch WhatsUp Gold)] is good for what it is. An inexpensive but accurate monitor for alerting on systems and services. However, it is time consuming to configure, The GUI leaves a lot to be desired and the formatting for txt alerts stinks (I just use it now as an alert to check my email to view the actual alert.)
Monitoring the connection; performance, switching, and issues. We use a broadband connection for our primary and a cellular backup for the secondary. While we use routing protocols to make this switch and WhatsUp isn't used for Syslog monitoring. it alerts us within seconds.
Backup configurations and archiving. WhatsUp does this particularly well. I use it for both Cisco routers and switches.
The diagram feature is nice. Though I don't use it as much because of the size of our structure, it does come in handy for mapping routes of all traffic.
Navigating the new WhatsUp Gold 2018 is a bit complicated and not user-friendly. The best part about using a software is the user's ability to use it with ease.
You cannot click sites being monitored from Map Dashboard View. This feature was previously possible in the older version.
I haven't used other products that are similar to Observium. Observium is an open tool, with a robust feature set. There are elements of comparable monitoring across other tools, but nothing I've seen that is a complete parallel in terms of feature set and visualizations. If I were asked, I wouldn't have another tool to recommend over Observium.
Progress WhatsUp Gold (formerly Ipswitch WhatsUp Gold) is more network focused than some of the other products we looked at, which had basic capabilities but were not as strong on the reporting or programmatic resolution of issues. Progress WhatsUp Gold (formerly Ipswitch WhatsUp Gold) is cost effective compared to some of the other upmarket solutions.
