Visit siteWeb-based traffic analysis and flow collection tool from ntop that provides real-time network traffic visibility.
Visit siteNetwork monitoring software discovers and maps network devices such as routers, switches, firewalls and servers, then polls them for health and performance data and alerts administrators to problems. Common techniques include SNMP polling, flow analysis such as NetFlow and IPFIX, and synthetic tests.
SNMP monitoring queries devices for status and counters such as interface utilization, errors and CPU load. Flow analysis collects traffic records exported by devices to show who is talking to whom, which applications use the bandwidth and where congestion occurs.
Open-source tools such as Zabbix, LibreNMS, Icinga and OpenNMS offer flexibility and no license cost but need more setup and operational effort. Commercial products typically add easier deployment, support, polished dashboards and managed or cloud-hosted options.
