更改Kibana5.x檢查Elasticsearch的license狀態

因爲本司多個Elasticsearch集羣使用一個kibana集羣,原本Elasticsearch集羣都是5.x,有一個日誌集羣須要升級到6.x,升級完以後kibana就不識別Elasticsearch6.x 的basic license(通過測試,kibana6.x不存在問題),這樣致使查看不了集羣狀態,可是又不能把kibana升級到6.x(其餘Elasticsearch5.x集羣是5.x),無奈只能修改kibana原來來達到目的.

修改kibana x-pack源碼

• 編輯文件

---

${kibana_home}/plugins/x-pack/plugins/monitoring/server/lib/cluster/get_clusters_from_request.js

• 修改該文件裏面的函數

---

normalizeClustersData
該方法是kibana獲取Elasticsearch集羣數據的最後調整的函數,在這裏,咱們能夠調整本身想要的數據,不單單是license

• 調整內容

  export function normalizeClustersData(clusters) {
  clusters.forEach(cluster => {
  cluster.elasticsearch = {
    cluster_stats: cluster.cluster_stats,
    nodes: cluster.nodes,
    indices: cluster.indices
  };
  cluster.status = calculateOverallStatus([
    cluster.elasticsearch.status,
    cluster.kibana && cluster.kibana.status || null
  ]);
  	//我手動添加的內容
  	cluster.isSupported = true;//突破basic license只能同時在kibana看一個Elasticsearch的限制
  	//我手動添加的內容,修改全部Elasticsearch集羣的license內容,使之都有效
  	cluster.license={
  	    "status": "active",
  	    "uid": "dfee2a04-bc89-4f84-bcde-39ce31e3ec5d",
  	    "type": "basic",
  	    "issue_date": "2019-02-21T04:38:03.373Z",
  	    "issue_date_in_millis": 1550723883373,
  	    "expiry_date": "2029-03-23T04:38:03.373Z",
  	    "expiry_date_in_millis": 1553315883373,
  	    "max_nodes": 1000,
  	    "issued_to": "elasticsearch",
  	    "issuer": "elasticsearch",
  	    "start_date_in_millis": -1,
  	    "hkey": "133893e5d3ae10145b0bc9d6600db8bd6ca4a8fe91fd1eac3"
  	};
  delete cluster.cluster_stats;
  delete cluster.nodes;
  delete cluster.indices;
  });
  
  return clusters;

}
