SNMP integration

The SNMP integration provides network device monitoring for virtually all network hardware like switches, routers, and firewalls. These devices can’t run a collector locally. Instead, Grafana Alloy polls these devices remotely over SNMP.


What it’s for	Monitoring network interfaces, device health, and hardware status
Under the hood	Polls devices via SNMP v2c or v3 using standard and vendor MIBs

Metrics collected

The integration polls each device for these metric groups:

Interfaces: Traffic, errors, status per port
Device: CPU, memory, uptime
Hardware: Temperature, fans, power

What to know

This integration offers:

Prebuilt dashboards: overview, fleet overview, logs
Prebuilt alerts: interface status, device health
No collector needed on devices

Some devices can’t run collectors, like switches, routers, and firewalls, but they still need monitoring. That’s where SNMP comes in.

SNMP, the Simple Network Management Protocol, is supported by virtually all network hardware. The integration polls devices and collects interface statistics, device CPU and memory, and hardware health like temperature and power.

Use SNMP version 3 when you can, since it adds the authentication and encryption that version 2c lacks. Configuration relies on MIBs, the definitions of what each device exposes, and you’ll want to plan polling intervals so thousands of devices don’t flood you with traffic.

For network teams, this fills a critical gap by monitoring infrastructure that collectors can’t reach.
