You can find these insights and recommendations in the following ways:\n\n- Use the Google Cloud console. Go to the [Kubernetes clusters](https://console.cloud.google.com/kubernetes/list) page. In the **Notifications** column for specific clusters, check for the **Free up space to reduce risk of cluster instability** recommendation.\n- Use the gcloud CLI or Recommender API by specifying the\n `ETCD_DB_USAGE_APPROACHING_LIMIT` recommender\n subtype.\n\n To query for this recommendation, run the following command: \n\n gcloud recommender recommendations list \\\n --recommender=google.container.DiagnosisRecommender \\\n --location \u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e \\\n --project \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e \\\n --format yaml \\\n --filter=\"recommenderSubtype:ETCD_DB_USAGE_APPROACHING_LIMIT\"\n\n| **Note:** This recommendation might take up to 24 hours to appear. For detailed instructions, see how to [view insights and recommendations](/kubernetes-engine/docs/how-to/optimize-with-recommenders#view-insights-recs).\n\nTo implement this recommendation, remove any unnecessary data from etcd to free up space. This might involve deleting old resources or moving large objects out of etcd.
