Not sure if it is because of our Corp Network, but Nagios runs a little slow. But it could be due to the large volume of network devices. Review collected by and hosted on G2.com.

When it comes to being organized and also having a good understanding of the network, some kind of tool is needed to make it happen. Nagios is that tool that keeps your devices in check and ensures that if something is wrong, you are made aware of it. I liked it a lot for when I had a smaller network and this was ensuring I kept my job. :) Review collected by and hosted on G2.com.

It is pretty entry level. Not bad overall, but also it is only good for smaller networks, can get chaotic when you add a ton of stuff to it, Plus the graphs are not alwways easy to read, you have to understand more than your average to get the graphs, and the different aspects of it. Not just networking. Review collected by and hosted on G2.com.

The basic features of Nagios Network Analyzer (as well as other software in the Nagios family) reside in a few configuration files. One for the monitored endpoints, one for each of the services of such endpoints, and group policies for different alarm/escalation settings profiles make it an excellent and extensive framework that is highly modifiable and adaptable for systems like monitoring routers, switches, firewalls, servers, and site locations.

We cannot see full visibility and are unable to recognize all traffic flows due to heterogeneous network topology, we are not able to deploy it for the production environment, it does not optimally support inter-VLAN routing scenarios but it remains undoubtedly the top choice for having a complete and comprehensive view, as well as the most in-depth insight on WAN links at the edge level or circuit terminating/aggregating router.

As an ISP working with a large network, we use Nagios to monitor it. It eases our workload by providing critical alerts on devices and network flow. The interface is excellent, making it easy to understand and maintain our network infrastructure. It helps us know bandwidth utilization and traffic flow in our network.

Configuration should be made easy, and sometimes it gives off fake alert sounds. Review collected by and hosted on G2.com.
