Its modularity provides huge flexibility allowing you to safely configure multiple servers of diverse types on different locations depending on your network requirements.
You can also deploy the solution as a standalone server and still monitor the whole infrastructure by using multiple network adapters.
Once you install from the Centos based ISO, you have all the tools you may need. It is not necessary (but it´s possible) to add multiple plugins/addons to set up the monitoring Agents.
It integrates multiple options/protocols to safely transfer data betwen the external agents and the servers.
It allows you to keep track of multiple devices of diverse type from a single console using personalized scripts, so there its no limit on what can be monitored.
It is lightweight. Using 4 GB of RAM, a multicore CPU, and a decent hard drive it can support up to 2000 Agents reporting to a single server. Review collected by and hosted on G2.com.
