Sales, pre-sales, human resources, the company cafeteria: they’re all online. If the network is down, employees are angry and customers have gone elsewhere. That’s why network traffic monitoring is a critical part of maintaining a healthy enterprise.
Fixing network problems when they happen isn’t good enough. IT managers have to proactively watch systems and head off potential issues before they occur. This means observing network traffic and measuring utilization, availability, and performance.
A useful monitoring tool offers these features:
- real-time network monitoring
- an ability to detect outages in real time
- a mechanism for sending alerts
- integrations for network hardware, such as SNMP and NetFlow monitoring
This is a list of the best tools available for monitoring your network traffic. Several of them are sold as SaaS, others for running on-premises, and a couple are open-source with optional commercial versions. All of these tools offer more than just network monitoring. They also offer varying degrees of application, system, and web monitoring too.
