SNMP agent 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the SNMP agent monitor type for the Smart Agent Receiver.

Use this monitor to collect metrics from SNMP agents.

This integration is available for Kubernetes, Windows, and Linux.

Note

This monitor doesn’t support MIB lookups`.

Benefits 🔗

After you configure the integration, you can access these features:

View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.

Installation 🔗

Follow these steps to deploy this integration:

Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:
Configure the monitor, as described in the Configuration section.
Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

To use this integration of a Smart Agent monitor with the Collector:

Include the Smart Agent receiver in your configuration file.
Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

Read more on how to Use Smart Agent monitors with the Collector.
See how to set up the Smart Agent receiver.
Learn about config options in Collector default configuration.

Note

Provide an SNMP monitor entry in your Collector or Smart Agent (deprecated) configuration. Use the appropriate form for your agent type.

Splunk Distribution of OpenTelemetry Collector 🔗

To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your agent configuration:

receivers:
  smartagent/snmp:
    type: telegraf/snmp
    ...  # Additional config

To complete the monitor activation, you must also include the smartagent/snmp receiver item in a metrics pipeline. To do this, add the receiver item to the service > pipelines > metrics > receivers section of your configuration file. For example:

service:
  pipelines:
    metrics:
      receivers: [smartagent/snmp]

Smart Agent 🔗

To activate this monitor in the Smart Agent, add the following to your agent configuration:

monitors:  # All monitor config goes under this key
  - type: telegraf/snmp
    ...  # Additional config

The following is a sample Smart Agent monitor configuration:

monitors:
 - type: telegraf/snmp
   agents:
     - "127.0.0.1:161"
   version: 2
   community: "public"
   fields:
     - name: "uptime"
       oid: ".1.3.6.1.2.1.1.3.0"

The following is a sample Smart Agent monitor configuration using a discovery rule:

monitors:
 - type: telegraf/snmp
   discoveryRule: container_name =~ "snmp" && port == 161
   version: 2
   community: "public"
   fields:
     - name: "uptime"
       oid: ".1.3.6.1.2.1.1.3.0"

See Install and configure the SignalFx Smart Agent for an autogenerated example of a YAML configuration file, with default values where applicable.
