Cisco 3850

Cisco 3850

Plugin: go.d.plugin Module: snmp

Maintained by Netdata

Overview​

Monitor Cisco 3850 (switch) with Netdata over SNMP. Netdata recognizes the device automatically by its sysObjectID (recognized across 1 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-3850.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.

Default Behavior​

Auto-Detection​

Auto-detected as Cisco 3850 via sysObjectID/sysDescr.

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 collector in two ways:

MethodBest forHow to
UIFast setup without editing filesGo to Nodes → Configure this node → Collectors → Jobs, search for snmp, then click + to add a job.
FileIf 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.

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 collector from the Netdata web interface:

  1. Go to Nodes.
  2. Select the node where you want the snmp data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
  3. The Collectors → Jobs view opens by default.
  4. In the Search box, type snmp (or scroll the list) to locate the snmp collector.
  5. Click the + next to the snmp collector to add a new job.
  6. 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​

On top of the generic SNMP baseline (the Generic SNMP Device integration — interfaces, system, IP/TCP/UDP, host resources), this Cisco 3850 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.

150 metrics in 21 groups; each row is a chart context usable in alerts.
