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.

Scans servers and network devices through SNMP and reduces manual maintenance for our infrastructure team
I like how ServiceNow Discovery scans servers and network devices through SNMP. Most fields on our forms are auto-filled, reducing manual maintenance for our infrastructure team. Post Discovery implementation there is hardly any maintenance. There are three to four fields that are customized. Otherwise, 90% of the data is auto-filled. Discovery can also run in bulk, which is helpful for organizations that cannot run it during weekdays. With identification rules, if a configuration item (CI) isn't in the CMDB, you can simply add the IP address, and it will be automatically added based on criteria like name or serial number, making CMDB maintenance easier.
