SNMP integration

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 forMonitoring network interfaces, device health, and hardware status
Under the hoodPolls 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

Script

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.
