Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ASM Naushad Alam - PeerSpot reviewer
Allows any number of customizations but lacks functionality for finding root causes
We have not yet purchased the commercial version so have a lack of technical ability. We do not yet fully know the key points or key features of the solution. We just use what we use along with WhatsUp Gold. Based on our use only, stability is rated a seven out of ten.

I think that your best bet of the two is Nagios. I would also take a look a CA Nimsoft Monitor Freemium. This will have more OOTB functionality for you sir.

ZABBIX ... of course :) We have been working with this wonderful monitoring tool since 2007 (before we had used Nagios, Openview, Whatsup, Hobbitmon, etc) and until now we haven't seen any limitations in our projects. If you need to learn a little bit more about 'how to customize ZABBIX' you can search about: - ZABBIX UserParameters; - ZABBIX pluggable modules; - ZABBIX LLD; - ZABBIX API; I think this things will help a lot to know how to extend/customize ZABBIX.
