I started with a free community edition, which was great for testing. Eventually, I upgraded to the professional edition for daily updates and real-time alerting features. I get it at an affordable price, and I feel it's a solid investment. Low maintenance. Once it's up and running, it just works. It's been running smoothly for over a year with minimal intervention. Clean web interface, I can drill down into device performance, historical graph, and spot trends easily. The good thing is that it can handle and monitor any networking device via SNMP, so it is very easy for our monitoring team to handle multiple types of network devices.

Reporting isn't good. Alerting setup is a bit complex. I had to dig through the documentation to get the email notification to work properly. Review collected by and hosted on G2.com.
