Network Monitoring Application of the Year

Groundwork ROCKZ!!!!

Nagios all the way!!!

My first post? (or just my first reply)

Nagios XI gets my vote every time!

Nagios, flawlessly flexible!

Nagios works for us monitoring cloud and on prem infrastructure.
Also applications!

Maybe I'm stretching the definition of "network monitoring" a bit far but I was going to vote for Wireshark. Absolutely indispensable for diagnosing network issues.

EDIT: Never mind, I found Wireshark in the network security category. Although it's more of a monitoring/diagnostic tool for me than security.

Zabbix

It's clear as day that Nagios is still forcing it's employees to come here and vote. Looking at the replies by users with 1-5 posts, and that they have only ever voted on these polls. Silly... they were doing this when I worked there too. Not that this poll really means much besides a news post for them.
