SNMP metrics

The OpenTelemetry Collector provides an integration with SNMP agents to scrape data. From there, the metrics are processed and exported to Cloud Observability.

To complete the integration, perform the following steps:

• Configure the SNMP agent
• Configure the Collector to use the SNMP receiver as a scrape target
• Enable the integration by adding it to a pipeline

Prerequisites

You’ve configured the Collector to export metric data to Cloud Observability.

Configure SNMP reporting

Configure the SNMP agent to expose data remotely using proper authorization settings.

rouser collector_user AuthPriv

Configure the Collector receiver

In the Collector configuration file, specify SNMP agent as a target endpoint and what metrics need to process.

              - resource_attr.name.1

Enable the Collector receiver

After the SNMP receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.

Validate metrics are reporting to Cloud Observability

You can validate that the metrics are reporting to Cloud Observability from the Metric details section of the Settings page.

1. Open the Settings page and scroll to the Metric details section.

2. Search for SNMP metric names, those were configured in the collector config.

3. If needed, select the metric to edit the description and how the units are displayed in Cloud Observability.

Create a dashboard for the metrics

Use the Cloud Observability Terraform Provider to create a dashboard for the metrics.
