Configure the Prometheus receiver to collect NetApp metrics

Configure the Prometheus receiver to collect NetApp metrics.

Cisco AI PODs are designed to integrate with high-performance storage solutions. You can monitor the performance of Cisco AI PODs that use NetApp storage resources with NetApp Trident, a storage orchestrator and management tool for containers and Kubernetes distributions.

Splunk Observability Cloud uses the Prometheus receiver to collect metrics from NetApp Trident, which exposes a /metrics endpoint that publishes Prometheus-compatible metrics.

To configure the Prometheus receiver to collect NetApp Trident metrics, you must meet the following requirements.

  1. Activate the Prometheus receiver for NetApp Trident manually in the Splunk Distribution of the OpenTelemetry Collector configuration by making the following changes to your values.yaml configuration file.
    1. Add prometheus/trident to the receiver_creator/cisco_ai_pods section. For example: 
      receiver_creator/cisco-ai-pods: 
  # Name of the extensions to watch for endpoints to start and stop. 
  watch_observers: [ k8s_observer ] 
  receivers: 
    prometheus/trident: 
      config: 
        config: 
          scrape_configs: 
            - job_name: trident-metrics 
              scrape_interval: 10s 
              metrics_path: /metrics 
              static_configs: 
                - targets: 
                  - '`endpoint`:8001' 
         rule: type == "pod" && labels["app"] == "controller.csi.trident.netapp.io"
    2. Add the receiver_creator/cisco-ai-pods receiver in the metrics pipeline of the service section, if it's not already present. For example: 
      metrics/cisco-ai-pods: 
  exporters: 
    - signalfx 
  processors: 
    - memory_limiter 
    - batch 
    - resourcedetection 
    - resource 
  receivers: 
    - receiver_creator/cisco-ai-pods
  2. Use Helm to apply the configuration changes:
    helm upgrade ucs-otel-collector \ 
--set="clusterName=$CLUSTER_NAME" \ 
--set="environment=$ENVIRONMENT_NAME" \ 
--set="splunkObservability.accessToken$SPLUNK_ACCESS_TOKEN\ 
--set="splunkObservability.realm=$SPLUNKREALM" \ 
--set="splunkPlatform.endpoint=$SPLUNK_HEC_URL" \ 
--set="splunkPlatform.token=$SPLUNK_HEC_TOKEN" \ 
--set="splunkPlatform.index=$SPLUNK_INDEX" \ 

-n otel \ 
-f ./base-otel-collector-config/values.yaml \ 
splunk-otel-collector-chart/splunk-otel-collector
