Where NetSense goes beyond what a general-purpose monitoring tool can offer ISPs.
NetSense monitors every layer of your FTTH network from OLT to ONU to CPE. Track ONU signal levels, detect partial PON failures, and trend fiber degradation. Observium sees devices as generic SNMP endpoints without ISP-specific context.
NetSense is a fully managed cloud platform. No servers to maintain, no databases to tune, no storage to plan. Observium requires a dedicated Linux server, MySQL, and RRD storage that you manage yourself.
Smart alert correlation reduces noise by 95%, so your NOC focuses on real issues. Escalation policies and 10+ notification channels keep the right people informed. Observium offers basic threshold alerts with limited routing.
Manage CPE remotely with zero-touch provisioning, WiFi telemetry, and remote diagnostics. Correlate customer-side issues with network-side data in a single platform. Observium has no CPE management capabilities.
