SNMP Device Monitoring

Real-Time Visibility Across Every SNMP Device

Q: What SNMP versions does Netdata support?

Netdata supports SNMP v1, v2c, and v3. For SNMPv3, full USM authentication and privacy are supported, including MD5, SHA (all variants through SHA-512), and AES encryption (AES-128 through AES-256 with Blumenthal and Reeder variants). SNMPv3 context name is supported for per-context MIB-view addressing on multi-context agents.

Q: How fast can Netdata poll SNMP devices?

The default polling interval is 10 seconds. Netdata supports per-second SNMP polling where the device can sustain it — the practical collection frequency is determined by each device’s ability to respond and accommodate the polling rate. This is 30x to 300x finer than the 5-minute polling typical of legacy NMS tools. If a device cannot keep up, Netdata logs the gap so you can tune the interval.

Q: Do I need to manually configure OIDs?

No. Netdata ships with 100+ built-in vendor profiles that auto-match devices by their sysObjectID and sysDescr. Common hardware from Cisco, Arista, Juniper, Palo Alto, FortiGate, F5, Aruba, HPE, Dell, and many more is monitored out of the box. For devices not covered by stock profiles, you can add custom profile YAML files.

Q: Can Netdata discover SNMP devices automatically?

Yes. Netdata’s optional auto-discovery scans configured subnets (up to 512 IPs per subnet), identifies SNMP-enabled devices, and automatically creates monitoring jobs with the right profiles and credentials. The default service rule handles SNMPv2c and v3 without manual job creation.

Q: Does Netdata apply machine learning to SNMP metrics?

Yes. Netdata’s unsupervised ML trains 18 models per metric on all metrics from all sources, including SNMP. This provides real-time anomaly detection with a 99% false-positive reduction through multi-model consensus. Stock BGP alerts already use ML anomaly detection on per-peer transition and UPDATE activity. Learn more about anomaly detection.

Q: Can I monitor BGP peers and sessions?

Yes. Netdata monitors BGP peer availability, FSM state, established uptime, BGP UPDATE and message traffic, and route counts where the vendor MIB exposes them. The Snmp:bgp-peers live function provides a sortable table of all peers for fast troubleshooting. BGP profiles cover generic BGP4-MIB plus Cisco, Juniper, Nokia SR OS, Huawei, Arista, and Dell.

Q: Does Netdata track device licenses and subscriptions?

Yes. For supported vendors including Check Point, FortiGate, Cisco (traditional and Smart Licensing), Sophos, Blue Coat ProxySG, and MikroTik RouterOS, Netdata monitors license expiry dates, health states, and usage pressure — with stock alerts for upcoming expirations.

Q: How does SNMP polling fit with topology and traps?

SNMP polling, topology maps, and trap monitoring share the same device data in one UI. The collector polls metrics, the topology viewer maps the devices it already monitors, and traps capture asynchronous events. Everything sits alongside your servers, containers, and cloud in a unified platform with Netdata Cloud.

Poll your network devices with 100+ auto-matched vendor profiles, per-second-capable collection, and ML anomaly detection on every metric. Routers, switches, firewalls, load balancers, UPS, and sensors — all unified with your servers, containers, and cloud in one platform.

Network Monitoring That Works at Your Speed

Catch What 5-Minute Polling Hides

Most operational anomalies last under 10 seconds. Legacy NMS tools averaging over 5-minute intervals miss transient errors, microbursts, and interface flaps entirely. Netdata polls every 10 seconds by default and supports per-second SNMP polling where the device can sustain it — revealing the spikes and dips that coarse polling smooths away.

30x-300x finer than legacy polling

100+ Vendor Profiles, Zero OID Config

When Netdata connects to a device, it reads sysObjectID and sysDescr to auto-match the right vendor profile. Interface metrics from IF-MIB, BGP peer data, environmental sensors, and device-specific telemetry appear instantly — no MIB downloads, no OID spreadsheets, no per-device tuning. Need something custom? Drop a profile YAML in your config directory.

Discover Your Entire Network Automatically

Enable opt-in auto-discovery and Netdata scans your subnets — single IPs, ranges, or CIDR blocks up to 512 addresses — to find every SNMP-enabled device. Discovered devices are matched to profiles, wired to the right credentials, and turned into Virtual Nodes automatically. The default service rule handles SNMPv2c and v3 without manual job creation.
