# NetSense NMS: Full Documentation for LLMs

> NetSense NMS is a network monitoring system (NMS) built specifically for Internet Service Providers (ISPs) operating FTTH (Fiber-to-the-Home) networks. It monitors fiber networks end-to-end: OLTs (Optical Line Terminals), PON (Passive Optical Networks), ONUs/ONTs, switches, and customer-premises equipment (CPE) WiFi via TR-069. 30-second polling intervals, smart alert correlation with 95% noise reduction, multi-vendor support across 15+ OLT vendors. Built by Extreme Labs (https://extremelabs.io).

### SensyAI
- URL: https://netsense-nms.com/sensyai
- Purpose: AI troubleshooting layer of the NetSense platform
- Features: Search by any identifier (PPPoE username, ONU/CPE serial, MAC); full-path diagnosis across upstream, core, BNG, distribution switch, OLT, ONU/fiber, CPE, and WiFi; optical power and threshold checks; dying gasp (power) vs optical fault (fiber) separation; per-device WiFi signal and band from Pulse (TR-069); AI verdict separating ISP-side from in-home issues; live streaming diagnosis UI for support agents
- Coming: customer-facing chatbot on the same engine; NetSense Flow traffic correlation
- Differentiator: runs on data NetSense NMS and Pulse already collect; no new agents or collectors to deploy

### OLT Monitoring
- URL: https://netsense-nms.com/olt-monitoring
- Purpose: Detailed feature page for OLT (Optical Line Terminal) monitoring capabilities
- Features: Real-time CPU, temperature, memory monitoring; optical power level tracking; PON port utilization; ONU status and signal quality; multi-vendor support (Huawei, ZTE, Nokia, Calix, FiberHome, and 10+ more)
- Use cases: Proactive fault detection, capacity planning, SLA compliance, vendor consolidation
- Differentiator: Purpose-built OLT monitoring vs generic SNMP polling; NetSense understands OLT-specific metrics natively

### PON Monitoring
- URL: https://netsense-nms.com/pon-monitoring
- Purpose: Last-mile fiber network monitoring from PON port to customer ONU
- Features: Per-ONU optical signal tracking (Rx/Tx power, distance); partial PON failure detection; fiber degradation alerts; ONU registration monitoring; signal quality trending
- Key capability: Detects partial PON failures (fiber bends, dirty connectors, splitter degradation) before they cause customer-visible outages
- Differentiator: Goes beyond simple up/down; monitors optical budget per ONU to catch degradation early

### Switch & Port Monitoring
- URL: https://netsense-nms.com/switch-port-monitoring
- Purpose: Aggregation and access switch monitoring with port-level visibility
- Features: Per-port traffic (bits in/out), error and discard counters, utilization heatmaps, SFP optical diagnostics, VLAN tracking, PoE monitoring
- Use cases: Bandwidth planning, error troubleshooting, SFP health monitoring, port utilization optimization

### TR-069 ACS
- URL: https://netsense-nms.com/tr069-acs
- Purpose: TR-069 Auto-Configuration Server for remote CPE management and WiFi telemetry
- Features: Remote CPE provisioning and firmware management; WiFi signal strength and channel monitoring; connected device inventory; speed test triggering; configuration backup/restore
- Differentiator: Combines TR-069 ACS with NMS: one platform for both network infrastructure and customer WiFi quality. Most competitors offer either ACS or NMS, not both integrated.

### Network Topology
- URL: https://netsense-nms.com/network-topology
- Purpose: Interactive network topology maps with live status and alarms
- Features: Live maps built from Netbox sync or defined device links; on-demand dynamic topology views per device; interactive drag-and-drop maps; map version control with visual diff; dependency visualization; fault propagation tracking; multi-layer views (physical, logical)
- Use cases: Visual NOC dashboards, impact analysis during outages, network documentation

### Alerting & Escalation
- URL: https://netsense-nms.com/alerting
- Purpose: Smart alert correlation and escalation engine
- Features: 95% alert noise reduction through correlation (e.g., OLT down suppresses downstream ONU alerts); customizable escalation policies; multi-channel notifications (Telegram, Email, Slack, Webhook); maintenance windows; alert grouping by root cause
- Differentiator: ISP-aware correlation; understands OLT→PON→ONU hierarchy to reduce alert storms during fiber cuts or OLT failures

## Comparison Pages

### Compare Hub
- URL: https://netsense-nms.com/compare
- Purpose: Overview of all available competitor comparisons
- Competitors compared: PRTG, SmartOLT, Observium, LibreNMS, Zabbix

### NetSense vs PRTG
- URL: https://netsense-nms.com/compare/prtg
- Summary: PRTG is Paessler's enterprise all-in-one monitoring platform with 250+ sensor types and sensor-based pricing. NetSense is purpose-built for ISPs with native OLT/PON understanding, flat per-device pricing, and zero infrastructure overhead.
- Key differences: PRTG requires Windows server + sensor licensing; NetSense is cloud SaaS. PRTG treats OLTs as generic SNMP devices; NetSense has vendor-specific OLT parsers. PRTG pricing scales with sensor count; NetSense prices per device.

### NetSense vs SmartOLT
- URL: https://netsense-nms.com/compare/smartolt
- Summary: SmartOLT is a cloud-based OLT management tool focused on ZTE and Huawei provisioning. NetSense provides full-stack ISP monitoring (15+ OLT vendors, switches, topology, alerting, TR-069), a monitoring-first vs provisioning-first approach.
- Key differences: SmartOLT focuses on OLT provisioning (VLAN, service profiles); NetSense focuses on monitoring and fault detection. SmartOLT supports 2 vendors; NetSense supports 15+. NetSense adds switch monitoring, topology maps, and smart alerting.

### SmartOLT Alternative
- URL: https://netsense-nms.com/smartolt-alternative
- Summary: Replacement guide for ISPs moving off SmartOLT. Covers why ISPs are switching in 2026 (slowed feature pace, support responsiveness, provisioning-only scope, as reported by switchers), an evaluation checklist for any replacement, and a 4-step migration path with a parallel-run period.
- Key differences: NetSense is monitoring-first (fault detection, alerting, topology, TR-069) across 15+ OLT vendors; SmartOLT is provisioning-first for ZTE/Huawei. Migration uses SNMP auto-discovery with no infrastructure to deploy.

### NetSense vs Observium
- URL: https://netsense-nms.com/compare/observium
- Summary: Observium is a mature general-purpose SNMP monitoring platform. NetSense goes deeper with ISP-specific OLT, PON, and ONU monitoring that Observium's generic SNMP approach cannot provide.
- Key differences: Observium polls generic SNMP OIDs; NetSense has vendor-specific OLT data models. Observium requires self-hosting; NetSense is cloud SaaS. Observium has no TR-069 or customer WiFi monitoring.

### NetSense vs LibreNMS
- URL: https://netsense-nms.com/compare/librenms
- Summary: LibreNMS is a popular open-source NMS forked from Observium with broad device support and active community. NetSense provides purpose-built ISP monitoring with deeper FTTH visibility, managed cloud deployment, and TR-069 ACS.
- Key differences: LibreNMS is self-hosted open-source (requires server management, updates, scaling); NetSense is managed SaaS. LibreNMS has generic device support; NetSense has ISP-native OLT/PON parsers. LibreNMS community provides OLT templates but they lack depth of purpose-built integration.

### NetSense vs Zabbix
- URL: https://netsense-nms.com/compare/zabbix
- Summary: Zabbix is a powerful open-source enterprise monitoring platform with extensive template ecosystem. NetSense delivers ISP-native OLT/PON monitoring without the template building, trigger configuration, and infrastructure overhead that Zabbix requires for FTTH use cases.
- Key differences: Zabbix requires template creation for each OLT vendor; NetSense has built-in vendor support. Zabbix needs dedicated infrastructure (database, web server, proxies); NetSense is cloud SaaS. Zabbix community has some FTTH templates but they require significant customization.
