Oid 1 SNMP Traps
Plugin: go.d.plugin Module: snmp_traps
Overview
Receive, decode, and store SNMP traps and INFORMs from Oid 1 devices with Netdata. The bundled Oid 1 trap profile decodes 216 trap definitions across 47 MIBs into structured journal events with named, typed varbinds — searchable and filterable in the Logs tab.
Netdata's SNMP trap listener receives traps on UDP/162, matches them to the Oid 1 enterprise OID space, and decodes the varbinds using the bundled Oid 1 trap profile. No per-trap configuration.
This integration is supported on all platforms.
This integration supports multiple instances configured side-by-side.
Default Behavior
Auto-Detection
Traps from Oid 1 devices are decoded automatically once the device is pointed at the Agent's trap listener.
Limits
The default configuration for this integration does not impose any limits.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
You can configure the snmp_traps collector in two ways:
| Method | Best for | How to |
|---|---|---|
| UI | Fast setup without editing files | Go to Nodes → Configure this node → Collectors → Jobs, search for snmp_traps, then click + to add a job. |
| File | If you prefer configuring via file, or need to automate deployments (e.g., with Ansible) | Edit go.d/snmp.conf and add a job. |
UI configuration requires paid Netdata Cloud plan.
Prerequisites
SNMP access
SNMP must be enabled on the device and reachable from the Netdata Agent acting as the site's SNMP hub.
Configuration
Options
Configure the SNMP collector with the device hostname and SNMP credentials. See the SNMP collector reference for all options.
via UI
Configure the snmp_traps collector from the Netdata web interface:
- Go to Nodes.
- Select the node where you want the snmp_traps data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
- The Collectors → Jobs view opens by default.
- In the Search box, type snmp_traps (or scroll the list) to locate the snmp_traps collector.
- Click the + next to the snmp_traps collector to add a new job.
- Fill in the job fields, then click Test to verify the configuration and Submit to save.
- Test runs the job with the provided settings and shows whether data can be collected.
- If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.
via File
The configuration file name for this integration is go.d/snmp.conf.
The file format is YAML. Generally, the structure is:
update_every: 1
autodetection_retry: 0
jobs:
- name: some_name1
- name: some_name2
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/snmp.conf
Examples
There are no configuration examples.
Alerts
There are no alerts configured by default for this integration.
Metrics
Netdata decodes 216 trap definitions from Oid 1 across 47 MIBs into structured journal events. A trap is decoded only if the device actually sends it; inclusion here means the profile can decode it.
