We are looking to implement an NMS (netork monitoring software) in our company and have found many different products; Nagios, Kaseya, Zabbix, Zenoss, Munin, OpenNMS.
The core functionality that we need is patch management and server monitoring if a server goes down. We would use the NMS to monitor new OS servers that come out, and patch them; so it must provide compatibility for new server OS's almost immediately. Which of the products listed would do this?
Not to be biased but we would like to support FOSS if it all possible.
