Step 1: Deploy a supported OpenTelemetry Collector

Context

Deploy a supported OpenTelemetry collector if it's not already deployed. If it's already deployed, upgrade it to a supported version.

Supported OpenTelemetry collectors

The following minimum versions are required for Secure Application functionality that uses the Splunk Distribution of OpenTelemetry Collector on Kubernetes with Helm:

• Helm chart splunk-otel-collector-0.137.0 or above

Easiest deployment option

The easiest option is to deploy the Splunk Distribution of OpenTelemetry Collector on Kubernetes with Helm chart version splunk-otel-collector-0.137.0 or above. This Helm chart is preconfigured with everything you need for Secure Application.

1. Add the Helm repository:

   CODECopy

   helm repo add splunk-otel-collector-chart https://signalfx.github.io/splunk-otel-collector-chart

   helm repo add splunk-otel-collector-chart https://signalfx.github.io/splunk-otel-collector-chart

2. Install the collector, with splunkObservability.secureAppEnabled set to true on the helm install command:

   CODECopy

   helm install my-splunk-otel-collector --set="splunkObservability.secureAppEnabled=true,splunkObservability.realm=us0,splunkObservability.accessToken=xxxxxx,clusterName=my-cluster" splunk-otel-collector-chart/splunk-otel-collector

   helm install my-splunk-otel-collector --set="splunkObservability.secureAppEnabled=true,splunkObservability.realm=us0,splunkObservability.accessToken=xxxxxx,clusterName=my-cluster" splunk-otel-collector-chart/splunk-otel-collector

See Helm chart installation examples that have Secure Application enabled:
