Plugin: go.d.plugin Module: snmp
Monitor Cisco Legacy WLC (wireless lan controller) with Netdata over SNMP. Netdata recognizes the device automatically by its sysObjectID (recognized across 14 device identifiers) and collects the metrics this profile declares — on top of the generic SNMP baseline — with no manual OID configuration.
Netdata’s SNMP collector matches the device to the cisco-legacy-wlc.yaml profile via sysObjectID/sysDescr, then polls the OIDs it declares.
This integration is supported on all platforms.
This integration supports multiple instances configured side-by-side.
Auto-detected as Cisco Legacy WLC via sysObjectID/sysDescr.
The default configuration for this integration does not impose any limits.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
You can configure the snmp 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, 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. |
Important
UI configuration requires paid Netdata Cloud plan.
SNMP must be enabled on the device and reachable from the Netdata Agent acting as the site’s SNMP hub.
Configure the SNMP collector with the device hostname and SNMP credentials. See the SNMP collector reference for all options.
Configure the snmp collector from the Netdata web interface:
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
There are no configuration examples.
On top of the generic SNMP baseline (the Generic SNMP Device integration — interfaces, system, IP/TCP/UDP, host resources), this Cisco Legacy WLC profile adds the metrics below. Each is collected only where the device exposes the matching OID — inclusion means the profile requests it; availability depends on the device model and software.
38 metrics in 7 groups; each row is a chart context usable in alerts.
